BYW172F-TR

Overview

The BYW172F-TR is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a hermetically sealed SOD-64 package with plated axial leads. The device has a repetitive peak reverse voltage of 300 V and an average forward current rating of 3 A. Peak forward surge current capability reaches 100 A for a 10 ms half-sine wave pulse. Non-repetitive reverse avalanche energy is rated at 20 mJ. Electrical characteristics include a maximum forward voltage of 1.5 V at 9 A, a typical reverse recovery time of 75 ns, and a maximum reverse current of 1 μA at 25 °C.

Feature Summary

Fast avalanche sinterglass construction with glass passivated junction
Hermetically sealed package designed for high reliability
Soft recovery characteristics suitable for high-speed switching applications

Applications

Fast rectification in switch-mode power supplies (SMPS)

Procurement Notes

Verify the specific ordering code BYW172F-TR against the manufacturer's latest documentation to confirm availability and packaging details. Ensure that the 300 V reverse voltage rating aligns with the circuit requirements. Confirm compliance with RoHS directives and material categorization standards before finalizing procurement decisions.

Selection Notes

Select this component when a 300 V blocking voltage and 3 A continuous current are required in a compact SOD-64 form factor. Consider the 100 A surge capability for transient protection scenarios. Evaluate thermal resistance values based on the specific lead length and PCB spacing conditions to ensure adequate heat dissipation under operating loads.

Part Context

This part belongs to the BYW172 series, which includes variants with different reverse voltage ratings such as the BYW172D (200 V) and BYW172G (400 V). All models share the same SOD-64 package and 3 A average forward current rating. The series is characterized by its sinterglass technology and fast recovery performance.
