BAT54T REG Equivalent & Substitute Parts

Part Overview

The BAT54T REG is a Schottky diode array manufactured by Taiwan Semiconductor Corporation, featuring three independent diodes rated for 30 V DC reverse voltage and 200 mA average rectified current per diode. The device is housed in a 6-TSSOP (SC-88, SOT-363) surface mount package and is classified as an active product. This component is commonly used in signal switching, protection circuits, and low-voltage rectification applications where fast switching speed and low forward voltage drop are required. Equivalent and substitute parts are identified based on matching electrical specifications, package compatibility, and compliance certifications.
