Overview
The BYV27-200-TAP is an ultra-fast avalanche sinterglass diode from Vishay, rated for a repetitive peak reverse voltage of 200 V and an average forward current of 2 A. It features a maximum forward voltage of 1.07 V at 3 A and a peak reverse recovery time of 25 ns. The device operates within a junction temperature range of -55 °C to +175 °C and supports a peak non-repetitive forward surge current of 50 A.
Feature Summary
- Controlled avalanche characteristic for inductive load switching
- Ultra-fast recovery time with low forward voltage drop
- Hermetically sealed glass passivated junction
Applications
- Very fast rectification in switch mode power supplies
Procurement Notes
Verify the specific ordering code BYV27-200-TAP against official Vishay documentation to confirm packaging details. Ensure that the component meets all required electrical parameters for your application before procurement.
Selection Notes
Select this component when high-speed rectification and avalanche ruggedness are required. Consider the SOD-57 package constraints and thermal resistance values for your specific circuit layout and ambient temperature conditions.
Part Context
This part belongs to the BYV27 series of ultra-fast avalanche sinterglass diodes. Other variants in the series include ratings of 50 V, 100 V, and 150 V, sharing similar structural and performance characteristics.
Replacement Considerations
Direct replacements must match the 200 V rating, 2 A current capacity, and SOD-57 package. Verify compatibility with avalanche requirements if present in the original design.
FAQ
