BAT54S

BAT54S Description

The BAT54S from SMC Diode Solutions is a 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, it offers low forward voltage drop (1V @ 100mA) and ultra-fast switching with a reverse recovery time (trr) of just 5ns. Its 30V maximum reverse voltage and low leakage current (2µA @ 25V) make it ideal for high-efficiency circuits. The device operates over a wide temperature range (-55°C to +125°C) and complies with ROHS3 and REACH environmental standards. Packaged in Tape & Reel (TR), it is optimized for automated assembly.
