BYWB29-200HM3/I

Overview

The BYWB29-200HM3/I is an ultrafast rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a single diode configuration housed in a TO-263AB (D2PAK) surface-mount package. The device supports a maximum repetitive peak reverse voltage of 200 V and a maximum average forward rectified current of 8.0 A at a case temperature of 105 °C. Key electrical parameters include a maximum instantaneous forward voltage of 1.3 V, a peak forward surge current capability of 100 A, and a maximum reverse current of 10 µA. The component exhibits an ultrafast recovery time of 25 ns and operates within a junction temperature range of -65 to +150 °C.

Feature Summary

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

Applications

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

Procurement Notes

Verify the specific ordering code suffix against official documentation to confirm compliance requirements. The HM3 suffix indicates RoHS-compliant, halogen-free material categorization and AEC-Q101 qualification status. Confirm that the TO-263AB package variant matches the intended PCB footprint and thermal management design before finalizing procurement orders.

Selection Notes

Select this component for designs requiring fast switching speeds and robust surge handling capabilities. Ensure the application circuit maintains the case temperature below 105 °C to sustain the rated 8.0 A average forward current. Verify that the system's peak reverse voltage does not exceed the 200 V rating under all operating conditions.

Part Context

This part belongs to the BYW29/BYWB29 series of ultrafast rectifiers from Vishay. The series offers various voltage ratings ranging from 50 V to 200 V. The BYWB29 variant specifically denotes the D2PAK (TO-263AB) surface-mount package option, providing a compact solution for high-power density applications compared to through-hole alternatives.

Replacement Considerations

Check datasheet specifications for direct pin-compatible substitutes within the same series or equivalent performance metrics from other manufacturers.
