BY229B-600HE3/45

Overview

The BY229B-600HE3/45 is a surface-mount standard recovery rectifier manufactured by Vishay General Semiconductor. It features a peak repetitive reverse voltage of 600 V and an average forward rectified current of 8 A. The device utilizes a TO-263AB (D2PAK) package for PCB mounting. Key electrical characteristics include a maximum forward voltage drop of 1.1 V at 8 A and a low reverse leakage current of 5 µA at 600 V. It operates within a junction temperature range of -55°C to 175°C.

Feature Summary

• Glass passivated chip junction for enhanced reliability
• Superfast recovery time optimized for high efficiency
• Low leakage current performance under reverse bias

Applications

• High-frequency switching power supplies
• Free-wheeling diode applications in converters
• DC-DC converter output rectification

Procurement Notes

Verify the specific suffix HE3/45 against the manufacturer's latest datasheet to confirm pinout and RoHS compliance status. Ensure the TO-263AB footprint matches the target PCB design. Confirm availability as distribution statuses change frequently.

Selection Notes

Select this component when a surface-mount solution is required for 600V, 8A applications. The D2PAK package offers superior thermal dissipation compared to smaller packages. Verify that the superfast recovery characteristics align with the circuit's switching frequency requirements.

Part Context

This part belongs to the BY229B series of fast-switching plastic rectifiers from Vishay. The series includes variants with different reverse voltage ratings, such as 200V and 400V options, all sharing similar current handling capabilities and package styles for modular design flexibility.

Replacement Considerations

Direct substitutes include other Vishay parts in the same series with adjusted voltage ratings, such as BY229B-400HE3/45 or BY229B-200HE3/45, provided the system voltage headroom allows.
