Conducts in forward bias direction Anode connected to positive batt54a and Cathode connected to ground Only leakage current up to 0. In the above circuit BAT54A is used as a protection diode for the microcontroller.

Panjit International Inc

The current flows in to the device from this pin. With that the characteristics of BAT54A can be given as:.

In the above circuit BAT54A protects sensitive Microcontroller from reverse voltage datashfet in a similar way we can use the device in other application circuits.

Now for an instant consider the PSU polarity is connected wrongly. Submitted by admin on 22 November The current flows out from the device through this pin.

Common Anode for the two schottky diodes in the device. The device being capable of carrying sizable currents while having low drop will lead to high efficiency which is a necessity in battery operated systems. Cathode for first schottky diode in the device. Cathode for second schottky diode in the device.

BAT54A Schottky Diode Pinout, Equivalent & Datasheet

Working of circuit When the supply unit delivers power the diode gets forward biased and current starts flowing. TL — Programmable Reference Voltage. 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.

BAT54A is used in circuits where power efficiency is important.

Because of current flow a voltage appears at the Microcontroller and this voltage will be very near to PSU voltage because the bat544a has very low drop during forward conduction. BAT54A is designed to be capable of recovering from forward conduction to blocking reverse voltage taking only 5nS so that it can be operated high frequency applications.

So under error connection there will be zero voltage appearing across the Microcontroller thus saving it from damage. The device being designed to have low voltage drop during conduction will become necessary in low voltage circuits where conduction voltage drop cannot datasneet afforded.

Here the power supply unit delivers power Microcontroller while diode in series is for protection. BAT54A can be operated like any bzt54a rectifier diode and can be installed in rectifier and protection circuits.
