BYG10Y

Overview

The BYG10Y is a standard avalanche surface-mount rectifier diode manufactured by Diotec Semiconductor. It features a DO-214AC (SMA) package and supports a maximum average forward rectified current of 1.5 A with a repetitive peak forward current rating of 5 A. The device provides a repetitive peak reverse voltage of 1600 V, with a maximum non-repetitive peak reverse avalanche energy of 20 mJ. Electrical characteristics include a forward voltage of less than 1.15 V at 1.5 A, a leakage current under 5 µA at 25°C, and a typical reverse recovery time of 1500 ns. Operating temperatures range from -50°C to +150°C.

Procurement Notes

Verify the specific ordering suffix against official documentation to confirm exact electrical tolerances and automotive qualification status. Ensure the component matches the required DO-214AC footprint and terminal plating specifications for your assembly process. Cross-reference the datasheet revision date to validate thermal resistance values and derating curves prior to finalizing procurement orders.

Selection Notes

Select this component when circuit designs require high-voltage blocking capabilities combined with moderate current ratings in a compact surface-mount form factor. Consider the 1600 V rating for mains or industrial power stages where avalanche robustness is necessary. Evaluate the thermal management requirements based on the specified junction-to-ambient thermal resistance for your specific PCB copper pad layout.

Part Context

This part belongs to the BYG10 series of standard avalanche SMD rectifiers from Diotec Semiconductor. The series covers various voltage ratings from 400 V to 1600 V within the same physical package family. The 'Y' designation specifically identifies the 1600 V variant within this standardized product line, ensuring mechanical interchangeability across different voltage grades.

Replacement Considerations

Check for compatible parts such as BYG10M or BYG10K if lower voltage ratings are acceptable. Verify that substitute components maintain the DO-214AC package dimensions and equivalent avalanche energy ratings.
