Overview
The BYC5D-500,127 is a hyperfast power diode manufactured by WeEn Semiconductors. It features a maximum repetitive peak reverse voltage of 500V and an average forward current rating of 5A. The device utilizes a SOD59 (TO-220AC) plastic package with two leads. Key electrical parameters include a forward voltage of 1.15V at 5A, a maximum non-repetitive surge forward current of 40A, and a typical reverse recovery time of 16ns. The component supports a maximum junction temperature of 150°C.
Feature Summary
- Hyperfast recovery characteristics for efficient switching applications
- High thermal stability with a maximum junction temperature of 150°C
- Robust surge current handling capability up to 40A
Applications
- High-frequency rectification in power supplies
- Free-wheeling diodes in DC-DC converters
- Snubber circuits in electronic ballasts
Procurement Notes
Verify the complete ordering part number includes the suffix ',127' to ensure correct packaging configuration. Confirm RoHS compliance status and lead-free plating specifications against the latest manufacturer documentation before procurement. Ensure the TO-220AC package dimensions match the target PCB footprint requirements.
Selection Notes
Select this component when hyperfast recovery times are critical for minimizing switching losses. The 500V rating suits medium-voltage AC/DC conversion stages. Evaluate the 5A continuous current capacity against the circuit's thermal management capabilities. Consider the TO-220AC package for through-hole mounting solutions requiring robust mechanical fixation.
Part Context
This device belongs to the BYC series of hyperfast rectifiers from WeEn Semiconductors. It serves as a successor or equivalent to similar NXP/Philips semiconductor products in the BYC family. The component is designed for general-purpose high-speed rectification where low reverse recovery charge is required.
Replacement Considerations
Cross-reference with other BYC5D-500 variants from different manufacturers. Verify pinout compatibility and thermal resistance values when substituting with generic equivalents.
