BYW172G-TR Description

Short technical summary and product information.

The BYW172G-TR is a fast avalanche sinterglass diode from Vishay Semiconductors, designed for high-reliability rectification applications. It features a glass passivated junction and hermetically sealed SOD-64 axial package, ensuring robust performance in demanding environments.

 

Key electrical specifications include a maximum repetitive peak reverse voltage of 400V, average forward current of 3A, and typical forward voltage of 1.1V at 3A. The diode offers a fast reverse recovery time of 100ns and a peak forward surge current capability of 100A for 10ms half sine wave. It also provides non-repetitive reverse avalanche energy of 20mJ at 1A.

 

With a wide operating temperature range of -55°C to 175°C and thermal resistance of 25 K/W (lead length 10mm) or 70 K/W on PCB, it is suitable for switch-mode power supplies (SMPS), snubber circuits, and freewheeling diode applications. The axial leads are plated and solderable per MIL-STD-750, method 2026, and the device weighs approximately 858 mg.
