BAT54C

BAT54C Description

The BAT54C from EIC Semiconductor, Inc. is a dual common cathode small-signal Schottky diode designed for high-efficiency rectification and switching applications. Packaged in a compact 3-pin SOT-23 form factor (2.9mm × 1.43mm × 1.3mm), it offers a 30V maximum DC reverse voltage and 0.2A continuous forward current, making it ideal for low-power circuits. With an ultra-fast 5ns peak reverse recovery time and a low forward voltage drop of 1V @ 0.1A, the BAT54C minimizes power losses and enhances switching performance. Its 10pF maximum diode capacitance ensures minimal signal distortion in high-frequency applications.

BAT54C Features
