Overview
The BYT56A-TAP is a single avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 50 V and an average rectified current of 3 A. The forward voltage is specified as 1.4 V at 3 A. Designed for through-hole mounting, it utilizes the SOD-64 axial package. The component operates within a junction temperature range of -55°C to 175°C.
Feature Summary
- Avalanche rated construction for robust operation
- High thermal stability with extended junction temperature range
- Through-hole axial leaded packaging for standard board integration
Applications
- General purpose rectification in power supplies
- Protection circuits requiring avalanche capability
- Industrial control systems
Procurement Notes
Verify the specific suffix 'TAP' corresponds to the required tape-and-reel packaging configuration from the manufacturer's official documentation. Confirm that the 50V rating aligns with the circuit's peak inverse voltage requirements. Ensure the SOD-64 axial footprint matches the PCB design constraints before finalizing procurement orders.
Selection Notes
Select this component when a 3A current capacity and 50V blocking voltage are required in an axial package. The avalanche characteristic distinguishes it from standard rectifiers, making it suitable for applications where transient energy absorption may occur. Verify compatibility with existing thermal management strategies given the 175°C maximum junction temperature limit.
Part Context
This part belongs to the BYT56 series of fast recovery avalanche diodes from Vishay. The series includes variants with different reverse voltage ratings, such as the BYT56B (100V) and BYT56M (1000V). The BYT56A specifically denotes the 50V variant within this family of high-current axial diodes.
Replacement Considerations
Cross-reference with other Vishay BYT56 series parts like BYT56B-TAP for higher voltage needs. Verify pinout and package dimensions against alternative manufacturers' equivalents to ensure mechanical fit.
