Overview
The BYG23T-AQ is an ultrafast avalanche rectifier diode manufactured by Diotec Semiconductor. It features a maximum repetitive peak reverse voltage of 1300 V and an average forward rectified current of 1 A. The device exhibits a maximum reverse recovery time of 75 ns, ensuring rapid switching capabilities. It is housed in the SMA (DO-214AC) surface-mount package and supports a maximum operating junction temperature of 175°C. This component meets AEC-Q101 automotive qualification standards.
Feature Summary
- Ultrafast recovery characteristics for high-frequency switching applications
- Avalanche-rated construction for robust transient voltage handling
- Automotive-grade reliability compliant with AEC-Q101 standards
- High thermal stability supporting operation up to 175°C
Applications
- Automotive electronics systems requiring high-voltage rectification
- Industrial power supply circuits
- General-purpose rectification in high-temperature environments
Procurement Notes
Verify that the ordered part number includes the -AQ suffix to confirm AEC-Q101 automotive qualification status. Ensure compatibility with SMA (DO-214AC) footprint dimensions during PCB layout. Confirm that system requirements align with the 1300V reverse voltage and 1A current ratings. Check datasheet for specific thermal derating curves relevant to your operating conditions.
Selection Notes
Select this component when high reverse voltage blocking capability combined with fast recovery speed is required. The avalanche rating provides additional protection against inductive load switching transients compared to standard rectifiers. Consider the SMA package size constraints and the need for high-temperature operation up to 175°C when evaluating alternative packages or non-automotive grade devices.
Part Context
Diotec Semiconductor specializes in discrete semiconductor components including diodes, transistors, and MOSFETs. Founded in Germany in 1973, the company serves industrial, automotive, and consumer markets. The BYG23T-AQ belongs to their ultrafast rectifier series designed for demanding electronic applications requiring reliable performance under harsh electrical and thermal conditions.
Replacement Considerations
Publicly confirmed substitute part numbers are not available in the provided documentation. Verify pinout compatibility and electrical parameter margins before substituting with other SMA-packaged 1300V ultrafast diodes from different manufacturers.
