BYW29-150HE3/45

Overview

The BYW29-150HE3/45 is a single ultrafast rectifier manufactured by Vishay General Semiconductor. It features a glass passivated pellet chip junction and is housed in a TO-220AC package. The device supports a maximum repetitive peak reverse voltage of 150 V and an average forward rectified current of 8.0 A at a case temperature of 105 °C. Key electrical characteristics include a maximum instantaneous forward voltage of 1.3 V at 20 A, a maximum DC reverse current of 10 µA at 25 °C, and a typical reverse recovery time of 25 ns. The component operates within a temperature range of -65 to +150 °C.

Feature Summary

• Ultrafast recovery time with low switching losses for high efficiency
• Glass passivated pellet chip junction for reliability
• High forward surge capability
• Low forward voltage drop

Applications

• High frequency rectifier of switching mode power supplies
• Inverters
• Freewheeling diodes
• DC/DC converters

Procurement Notes

Verify the specific ordering code suffix against the manufacturer's official documentation to confirm compliance with RoHS standards and halogen-free requirements. Ensure that the selected variant matches the required thermal resistance and package dimensions for your application design. Cross-reference the datasheet revision date to validate all electrical parameters before finalizing procurement specifications.

Selection Notes

Select this component based on its 150 V reverse voltage rating and 8.0 A continuous current capacity. Consider the 25 ns reverse recovery time for high-frequency applications requiring fast switching speeds. Evaluate the thermal management requirements, as the device specifies an average forward current rating dependent on maintaining a case temperature of 105 °C or lower.

Part Context

This part belongs to the BYW29 series of ultrafast rectifiers from Vishay General Semiconductor. The series includes variants with different voltage ratings ranging from 50 V to 200 V. All models share similar structural features, including the glass passivated junction and TO-220AC or D2PAK packages, designed for robust performance in power switching environments.

Replacement Considerations

Consult the manufacturer's official cross-reference data for verified substitute part numbers. Do not assume functional equivalence based solely on package type or general category. Verify that any alternative component meets the specific 25 ns reverse recovery time and 8.0 A current requirements.
