BAT54CD REG

Overview

The BAT54CD REG is a surface-mount Schottky barrier diode array manufactured by Taiwan Semiconductor Corporation. It features four isolated diodes configured in two common-cathode banks, housed in a compact SOT-363 (SC-88) package. The device supports a maximum average forward current of 200 mA and a peak repetitive reverse voltage of 30 V. Key electrical characteristics include a low forward voltage drop of approximately 1 V at 100 mA and a fast switching speed with a reverse recovery time of 5 ns. It operates within a junction temperature range of -65°C to +150°C.

Feature Summary

• Four-element configuration providing two independent common-cathode diode banks for space-efficient circuit design.
• Extremely fast switching capability with a reverse recovery time of 5 ns, suitable for high-speed signal processing.
