BAT46SWFILM

Diode Arrays Overview

The BAT46SWFILM is a small signal Schottky diode manufactured by STMicroelectronics, housed in an SOT-323 surface-mount package. It features a series configuration of two diodes and carries the B46 marking code. The device supports a continuous forward current of 150 mA and withstands a repetitive peak reverse voltage of 100 V. Key electrical characteristics include a maximum forward voltage drop of 1 V at 250 mA, a typical junction capacitance of 6 pF at 1 MHz, and a non-repetitive surge forward current rating of 1 A. It operates within a temperature range of -65 °C to +150 °C.
