BAT54ZFILM

Single Diodes Overview

The BAT54ZFILM is a small signal Schottky diode manufactured by STMicroelectronics, designed for surface mount applications. It features a single diode configuration housed in an SOD-123 package with two pins. Key electrical parameters include a maximum repetitive reverse voltage (Vrrm) of 40 V and a maximum continuous forward current (If) of 300 mA. The device exhibits a peak non-repetitive forward surge current (Ifsm) of 1 A and a low peak reverse current (Ir) of 1 μA. Forward voltage (Vf) is specified at a maximum of 900 mV, with a peak reverse recovery time (trr) of 5 ns. The component operates within a temperature range of -40°C to +150°C.
