The current flows in to the device from this pin.

Working of circuit When the supply unit delivers power the diode gets forward biased and current starts flowing. Submitted by admin on 22 November In the above circuit BAT54A protects sensitive Microcontroller datasheer reverse voltage and in a similar way we can use the device in other application circuits.

With that the characteristics of BAT54A can be given as:. Under such state the diode gets reverse biased and based on BAT54A characteristics no current flows through the circuit during reverse bias. Cathode for second schottky diode in the device. The device bat54w capable of carrying sizable currents while having low drop will lead to high efficiency which is a necessity in battery operated systems.

Now for an instant consider the PSU polarity is connected wrongly. The device being designed to have low voltage drop during conduction will become necessary in low voltage circuits datasheft conduction voltage drop cannot be afforded.

With that the characteristics of BAT54A can be given as: So under error connection there will be zero voltage appearing across the Microcontroller thus saving it from damage. Common Anode for the two schottky diodes in the device.

BAT54A can be operated like any other rectifier diode and can be installed in rectifier and protection circuits. Here the power supply unit delivers power Microcontroller while diode in series is for protection.

Conducts in forward bias direction Anode connected to positive voltage and Cathode connected to ground Only leakage current up to 0. TL — Programmable Reference Voltage.

Because of current flow datasheft voltage appears at the Microcontroller and this voltage will be very near to PSU voltage because the device has very low drop during forward conduction.


The current flows out from the device through this pin. BAT54A is used in circuits where power efficiency is important. BAT54A is designed to be satasheet of recovering from forward conduction to blocking reverse voltage taking only 5nS so that it can be operated high frequency applications.

Cathode for first schottky diode in the device. In the above circuit BAT54A is used as a protection diode for the microcontroller.
