Avoid applying power exceeding normal rated power; exceeding the power rating under steady-state loading condition may negatively affect product performance and reliability.
Bd436 transistor datasheet pdf
The following are examples of safety measures: Their operation can result in mutual interference between circuits and can cause malfunctions and, in turn, physical damage to or destruction of the chip. ROHM shall not be in any way responsible or liable for any damages, expenses or losses dwtasheet by you or third parties resulting from inaccuracy or errors of or concerning such information.
Transient characteristics should be sufficiently verified. Normal bf433 should be within the power dissipation rating, if however the rating is exceeded for a continued period, the junction temperature Tj will rise and the TSD circuit will be activated and turn all output pins OFF. Therefore, when actually using the chip, ensure that the generated heat does not exceed the Pd rating.
Note that the TSD circuit operates in a situation that exceeds the absolute maximum ratings and therefore, under no circumstances, should the TSD circuit be used in a set design or for any purpose other than protecting the IC from heat damage.

As a protection from static electricity, ensure that the assembly setup is grounded and take sufficient caution with transportation and storage. We have now successfully completed our first stage – Opera. This protection circuit is effective in preventing dxtasheet due to sudden and unexpected incidents. Therefore, in case you use such information, you are solely responsible for it and you must exercise your own independent verification and judgment in the use of such information contained in this document.
Otherwise bent leads may occur due to excessive stress applied when dropping of a carton. Parasitic datzsheet inevitably occur in the structure of the IC.
ROHM does not warrant that foregoing information or data will not infringe any intellectual property rights or any other rights of any third party regarding such information or data. Also, make sure to turn off the power supply when connecting and disconnecting the inspection equipment.

Similarly, care must be taken to avoid wiring pattern fluctuations in any connected external component GND. A customer may use this translation version only for a reference to help reading the formal version. Ceramic capacitors can be used for compensation of the output capacitor phase. Also, shorts caused by dust entering between the output, input and GND pin may result in damaging the IC. Documents Flashcards Grammar checker. Only includes enable input Figure 8. However, the IC should not be used in applications characterized by continuous operation or transitioning of the protection circuit.
Low ESR ceramic capacitor can be used as output capacitor. After the Tj falls below the TSD threshold the circuits are automatically restored to normal operation. Baking is required before using Products of which storage time is exceeding the recommended storage time period. The product described in this specification is designed to be used with ordinary electronic equipment or devices such as audio-visual equipment, office-automation equipment, communications devices, electrical appliances, and electronic toys.
It is strongly recommended to confirm solderability before using Products of which storage time is exceeding the recommended storage time period. Not connected 4 N. Although the actual application might be the cause of the transients, the IC input voltage, output current and temperature are also possible causes.
High output voltage accuracy: Therefore do not employ any method in which parasitic diodes can operate such as applying a voltage to an input pin that is lower than the P substrate GND.
Includes switch Integrated overcurrent protection to protect the IC from damage caused by output short-circuiting. When used in sealed area, confirm the actual ambient temperature.
Incorrect mounting may result in damaging the IC.
These regulators are therefore ideal for applications requiring a direct connection to the battery and a low current consumption. For example, in case a resistor and a transistor are connected to the pins as shown in the figure below then: If you intend to use our Products under any special or extraordinary environments or conditions as exemplified belowyour independent verification and confirmation of product performance, reliability, etc, prior to use, must be necessary: Please take special care under dry condition e.
On the reverse side of the package this product has an exposed heat pad for improving the heat dissipation. Use both the front and reverse side of the PCB to increase the heat dissipation pattern as far as possible.
The amount of heat generated depends on the voltage difference across the input and output, load current, and bias current. Furthermore, these ICs also feature overcurrent protection to protect datahseet device from damage caused by short-circuiting and an integrated thermal shutdown to protect the device from overheating at overload conditions. ROHM shall not be in any way responsible or liable for any damages, expenses or losses incurred by you or third parties arising from the use of such information.
In case problems arise within the actual operating range, use countermeasures such as adjusting the output capacitance.
The absolute maximum rating of the Pd stated in datashewt specification is when bs433 IC is mounted on a 70mm X 70mm X 1. Please take proper caution in your manufacturing process and storage so that voltage exceeding the Products maximum rating will not be applied to Products. Should you intend to use this product with equipment or devices which require an extremely high level of reliability and the malfunction of which would directly endanger human life such as medical instruments, transportation equipment, aerospace machinery, nuclear-reactor controllers, fuel controllers and other safety devicesplease be sure to consult with our sales representative in advance.
If there are any differences in translation version of this document formal version takes priority Application example ROHM cannot provide adequate confirmation of patents. In datassheet event it also becomes impossible to determine the cause of the damage e.
This in order to separate the small-signal and high current patterns and to ensure that voltage changes stemming from the wiring resistance and high current do not cause any voltage change in datashret small-signal GND.
However, semiconductor products can fail or malfunction at a certain rate.
