BAT54S Schottky Diode – 30V Dual Switching Diode (SOT-23, KL4)

Product Description:
The BAT54S Schottky Barrier Diode is a compact, high-speed dual switching diode housed in a small SOT-23 surface-mount package. With its low forward voltage drop, fast switching capability, and high reliability, this diode is ideal for low-voltage rectification, signal switching, and high-frequency applications.

Featuring a peak repetitive reverse voltage of 30V and an average rectified current of 200mA, the BAT54S provides stable performance in compact, power-sensitive designs. Its Schottky junction ensures low power loss, while the KL4 marking makes identification easy during production and assembly.

The small footprint and excellent thermal performance make the BAT54S suitable for portable electronics, IoT devices, RF circuits, level shifting, clamping, and protection circuits where space efficiency and speed are essential.
