GF1A/17 – VISHAY

Overview

The Vishay GF1A/17 is a high-performance single standard recovery rectifier designed for efficient rectification in power supply and signal processing circuits. Its critical operational characteristic lies in its 1A forward current capability at a 50V reverse voltage, offering a robust solution for moderate power applications. A key design consideration for engineers is balancing its 1.1V forward voltage drop against switching speed requirements; while suitable for general rectification, applications demanding ultra-low power loss or extremely high frequencies may necessitate Schottky diodes, which offer lower Vf but typically at the cost of higher reverse leakage.

Key Features

• Maximum Reverse Voltage (Vr): 50 V
• Maximum Forward Current (If): 1 A

• Maximum Surge Current (Ifsm): 30 A (1/2 cycle, sine wave)
• Reverse Current (Ir): 5 µA @ 50V
• Standard Recovery Time: 3 µs
• Package: DO-214BA (SMD/SMT), 4.75 mm x 2.9 mm x 2.74 mm
