BYW172G-TAP

Overview

The BYW172G-TAP is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a SOD-64 package with plated axial leads and supports an average forward current of 3 A and a peak forward surge current of 100 A. The device has a maximum repetitive peak reverse voltage of 400 V, a maximum forward voltage of 1.1 V at 3 A, and a typical reverse recovery time of 75 ns. It operates within a junction temperature range of -55 °C to +175 °C.

Feature Summary

• Fast avalanche capability for high-voltage switching applications
• Soft recovery characteristics to minimize electromagnetic interference
• Hermetically sealed glass passivated junction for reliability
• Low forward voltage drop and low reverse leakage current

Applications

• Fast rectification in switch-mode power supplies (SMPS)
• High-frequency rectification circuits
• Avalanche energy dissipation applications

Procurement Notes

Verify the specific ordering code BYW172G-TAP corresponds to the 2500 units per ammopack configuration. Confirm that the minimum order quantity aligns with the manufacturer's standard requirement of 12,500 units. Ensure the component meets RoHS compliance standards as defined in the Vishay material categorization documentation before finalizing procurement.

Selection Notes

Select this component when a 400 V rating is required alongside a 3 A continuous current capacity. The SOD-64 through-hole package is suitable for designs requiring robust mechanical mounting. Consider the 75 ns reverse recovery time for high-speed switching requirements where soft recovery behavior is necessary to reduce circuit noise.

Part Context

This part belongs to the BYW172 series, which includes variants with different reverse voltage ratings such as the BYW172D (200 V) and BYW172F (300 V). All models share the same SOD-64 package and 3 A forward current rating but are differentiated by their breakdown voltage specifications.

Replacement Considerations

Direct substitutes include other Vishay BYW172 series parts like BYW172D or BYW172F if lower voltage ratings are acceptable. Cross-brand replacements must match the 400 V reverse voltage, 3 A forward current, and SOD-64 package dimensions.
