Overview
The BYG20D is an ultrafast avalanche surface-mount rectifier diode manufactured by Diotec Semiconductor. It features a maximum average forward rectified current of 1.5 A and a repetitive peak reverse voltage of 200 V. The device exhibits a maximum instantaneous forward voltage of 1.3 V at 1 A and 1.4 V at 1.5 A, with a reverse recovery time under 75 ns. It supports a non-repetitive peak forward surge current of 30 A and handles a non-repetitive peak reverse avalanche energy of 20 mJ. Operating temperatures range from -50°C to +150°C.
Feature Summary
- Ultrafast switching characteristics with low reverse recovery time for high efficiency
- Avalanche rated capability to withstand transient energy surges
- Glass passivated junction providing reliable operation and low leakage current
Applications
- High frequency switching power supplies
- Free-wheeling rectification in DC-DC converters
- Polarity protection circuits
Procurement Notes
Verify the specific ordering suffix against official documentation to confirm compliance requirements such as AEC-Q101 automotive qualification or halogen-free status. Confirm package dimensions and moisture sensitivity levels prior to integration into automated placement processes.
Selection Notes
Select this component for applications requiring fast recovery times and robustness against inductive load switch-off transients. Ensure thermal management accounts for the typical thermal resistance values provided in the datasheet to maintain junction temperature within specified limits during continuous operation.
Part Context
This part belongs to the BYG20 series of ultrafast SMD rectifiers, which includes variants with different reverse voltage ratings up to 600 V. The series is designed for general-purpose high-efficiency rectification in compact surface-mount designs.
Replacement Considerations
Cross-reference with other BYG20 series parts for different voltage ratings. Verify compatibility with alternative manufacturers' ultrafast rectifiers by matching current, voltage, and recovery time specifications.
