BYW29E-150,127

Overview

The BYW29E-150,127 is a single fast recovery rectifier manufactured by WeEn Semiconductors. It features a 150 V reverse voltage rating and an 8 A forward current capacity. The device exhibits a 1.3 V forward voltage drop and a 25 ns maximum reverse recovery time. It supports a peak non-repetitive surge current of 88 A with a leakage current of 10 uA. Designed for through-hole mounting in TO-220-2 packages, it operates reliably within a temperature range of -40°C to +150°C.

Feature Summary

• Ultra-fast recovery characteristics designed for high-frequency switching applications
• Glass passivation provides mechanical strength and stability against soldering tools
• Soft recovery profile minimizes electromagnetic interference during switching transitions

Applications

• Switched-mode power supplies (SMPS)
• High-frequency general circuits requiring low conduction losses
• Free-wheeling diodes in inductive load protection

Procurement Notes

Verify the specific suffix '127' corresponds to the required tape-and-reel or bulk packaging configuration as defined by the manufacturer's ordering guide. Confirm RoHS compliance status and REACH SVHC declarations directly from the official datasheet before finalizing procurement specifications.

Selection Notes

Select this component when circuit requirements demand an 8 A continuous current handling capability combined with a 150 V blocking voltage. The TO-220-2 package facilitates efficient thermal dissipation for high-power density designs. Ensure the system operating frequency aligns with the 25 ns recovery speed to optimize efficiency.

Part Context

This part belongs to the BYW29 series of ultrafast rectifiers produced by WeEn Semiconductors. The series is engineered for high-efficiency power conversion where minimizing switching losses is critical. The TO-220 form factor ensures compatibility with standard heatsinking solutions used in industrial power electronics.

Replacement Considerations

Cross-reference with other BYW29 series variants such as BYW29E-100 or BYW29E-200 if voltage ratings differ. Verify pinout compatibility and thermal resistance parameters when substituting with generic ultrafast rectifiers from other manufacturers.
