BYW178-TR

Overview

The BYW178-TR is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features an 800 V repetitive peak reverse voltage and supports a 3 A average forward current in the SOD-64 axial package. The device exhibits very fast reverse recovery characteristics, with a maximum reverse recovery time of 60 ns under JEDEC conditions and 50 ns at high dIF/dt. It operates within a junction temperature range of -55 °C to +175 °C and includes non-repetitive reverse avalanche energy capability.

Feature Summary

Glass passivated junction for enhanced reliability
Hermetically sealed sinterglass package construction
Soft recovery characteristics with low reverse current
Very fast reverse recovery time suitable for high-frequency applications

Applications

Ultrafast rectification in switching mode power supplies

Procurement Notes

Verify the specific ordering code against the manufacturer's documentation to ensure correct packaging configuration. Confirm that the component meets all required environmental and electrical specifications for the intended application before finalizing procurement decisions.

Selection Notes

Select this component when designing circuits requiring high-voltage blocking capabilities combined with rapid switching speeds. Ensure the thermal management strategy accounts for the specified thermal resistance values to maintain safe operating temperatures during continuous operation.

Part Context

This part belongs to the BYW178 series of fast avalanche sinterglass diodes from Vishay. It is designed for robust performance in demanding electronic environments, offering a balance of high voltage handling and fast switching characteristics in a compact axial leaded package.

Replacement Considerations

Consult official Vishay documentation for verified substitute part numbers. Do not assume compatibility with other manufacturers' components without validating electrical parameters and physical dimensions.
