Overview
The BYG10Y-AQ is a standard avalanche SMD 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 of 5 A. The device provides a repetitive peak reverse voltage of 1600 V and withstands a non-repetitive peak reverse avalanche energy of 20 mJ. Electrical characteristics include a maximum forward voltage of 1.15 V at 1.5 A, a leakage current of less than 5 µA at 25°C, and a typical reverse recovery time of 1500 ns. It operates within a junction temperature range of -50 to +150°C.
Feature Summary
- Standard avalanche capability for handling inductive load switch-off
- Automotive qualification compliant with AEC-Q101 standards
- High thermal stability across extended operating temperatures
Applications
- Automotive electronic systems requiring high reliability
- Inductive load switching circuits
- General industrial power supply applications
Procurement Notes
Verify the specific -AQ suffix indicates AEC-Q101 automotive qualification status as defined by the manufacturer. Confirm that the component meets the required environmental and reliability standards for your specific application before finalizing procurement. Ensure ordering documentation matches the exact part number to avoid discrepancies in automotive grade specifications.
Selection Notes
Select this component when a high-voltage rectifier with avalanche rating is required for SMA packages. The 1600 V rating suits high-voltage DC bus applications. Consider the 1.5 A current limit and thermal resistance values for heat dissipation planning. Verify compatibility with PCB layout constraints for the DO-214AC footprint.
Part Context
This component belongs to the BYG10 series of standard avalanche rectifiers from Diotec Semiconductor. The series includes variants with different voltage ratings such as BYG10D through BYG10M. The -AQ designation specifically denotes compliance with automotive quality standards, distinguishing it from standard commercial grade parts within the same electrical family.
Replacement Considerations
Cross-reference with other BYG10Y or BYG10Y-AQ parts from Diotec or equivalent manufacturers offering identical SMA package, 1600 V rating, and 1.5 A current capacity. Ensure any substitute also holds AEC-Q101 qualification if automotive use is intended.
