BAT54S

BAT54S Description

The BAT54S from Good Ark Semiconductor is a high-performance Schottky diode array configured as 1 pair series connection, housed in a compact SOT-23 surface-mount package. Designed for small-signal applications with currents up to 200mA (Io), it offers low forward voltage drop (1V max @ 100mA) and ultra-fast switching with a reverse recovery time (trr) of just 5 ns. With a maximum reverse voltage (Vr) of 30V and minimal reverse leakage current (2µA @ 25V), it ensures efficient power management and signal integrity in high-frequency circuits. Compliant with ROHS3 and REACH standards, it is ideal for modern electronics requiring reliability and environmental safety.
