GF1A-E3/67A – VISHAY

Overview

The Vishay GF1A-E3/67A is a high-performance 1A, 50V general-purpose rectifier diode, crucial for efficient power conversion and signal rectification in demanding electronic designs. Its key operational characteristic is its robust 1A current handling capability coupled with a low forward voltage drop of 1.1V at 1A, minimizing power dissipation. A critical design consideration when selecting this diode is its standard recovery time of 2µs; while suitable for many applications, designers must account for this characteristic in high-frequency switching circuits where faster recovery is paramount to prevent switching losses and potential ringing.
