Overview
The BYT56K-TAP is a fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features an 800 V maximum DC reverse voltage and a 3 A average rectified current rating. The device utilizes the SOD-64 axial through-hole package. Key electrical characteristics include a forward voltage of 1.4 V at 3 A and a reverse recovery time of less than or equal to 500 ns for currents greater than 200 mA. The junction temperature range extends from -55°C to 175°C.
Feature Summary
- Fast avalanche capability designed for high-voltage switching applications
- Sinterglass construction provides robust thermal performance
- Axial leaded SOD-64 package facilitates through-hole mounting
Applications
- High voltage switching circuits
- Flyback diodes in inductive load protection
- Snubber circuits for transient suppression
Procurement Notes
Verify the specific suffix 'TAP' indicates tape-and-reel packaging when ordering. Confirm the 800V rating aligns with circuit requirements, as other variants like BYT56J offer 600V. Ensure the SOD-64 axial package fits the PCB layout constraints. Cross-reference the manufacturer part number with official Vishay documentation to confirm current production status and datasheet revisions before finalizing procurement.
Selection Notes
Select this component when an 800V blocking voltage is required alongside a 3A continuous current capacity. The fast recovery characteristic makes it suitable for higher frequency switching compared to standard rectifiers. Consider the SOD-64 form factor for space-constrained through-hole designs. Evaluate thermal management needs given the 175°C maximum junction temperature limit.
Part Context
The BYT56K belongs to the BYT56 series of fast avalanche diodes from Vishay. This series includes variants with different voltage ratings, such as the BYT56G (400V) and BYT56J (600V). The 'K' designation specifically denotes the 800V breakdown voltage class within this family of sinterglass devices.
Replacement Considerations
Compatible substitutes within the same voltage class include the BYT56K-TR (tape and reel variant without TAP suffix) or other 800V 3A fast recovery diodes from Vishay's BYT series. Verify pinout compatibility and thermal resistance values when substituting.
