BAT54

Single Diodes Overview

The BAT54 is a silicon Schottky barrier diode manufactured by onsemi, housed in a surface-mount SOT-23-3 package. It features a maximum repetitive reverse voltage of 30 V and an average rectified forward current rating of 200 mA. The device supports non-repetitive peak forward surge currents up to 600 mA with a pulse width of 1.0 second. Electrical characteristics include a power dissipation capacity of 290 mW and a junction-to-ambient thermal resistance of 430 °C/W. Operating parameters specify a breakdown voltage of 30 V at 10 µA reverse current, with a maximum reverse leakage current of 2 µA at 25 V. Forward voltage ranges from 240 mV at 0.1 mA to 800 mV at 100 mA. The component exhibits a total capacitance of 10 pF at 1 V reverse bias and a reverse recovery time of 5.0 ns.
