BAW27-TR

Overview

The BAW27-TR is a single silicon epitaxial planar switching diode from Vishay Semiconductors, packaged in the DO-35 (DO-204AH) through-hole format. It features a repetitive peak reverse voltage of 75 V and a maximum forward continuous current of 600 mA. The device exhibits a low forward voltage drop, reaching up to 1.25 V at 400 mA, and a fast reverse recovery time of 6 ns. Electrical characteristics include a breakdown voltage of 75 V at 5 μA and a typical capacitance of 4 pF. Thermal management allows for a junction temperature up to 175 °C with power dissipation rated at 500 mW under standard conditions.
