Overview
The BYV26A-TR is an ultra-fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a glass passivated junction and hermetically sealed SOD-57 package with plated axial leads. The device supports a repetitive peak reverse voltage of 200 V and an average forward current of 1 A. Key electrical parameters include a maximum forward voltage of 2.5 V at 1 A, a reverse recovery time of 30 ns, and a peak forward surge current capability of 30 A. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Ultra-fast switching performance with very low switching losses
- Hermetically sealed package with glass passivated junction
- High reverse voltage rating with low reverse current
- Capable of handling non-repetitive reverse avalanche energy
Applications
- Switched mode power supplies
- High-frequency inverter circuits
Procurement Notes
Verify the specific part number suffix against official Vishay documentation to confirm packaging configuration and tape specifications. Ensure that the ordering code matches the required quantity per reel or ammopack as defined in the manufacturer's ordering information section. Cross-reference the document revision date to ensure compliance with current material categorization standards.
Selection Notes
Select this component for applications requiring high-speed rectification with avalanche capability. The SOD-57 through-hole package suits designs needing robust mechanical mounting. Consider the 30 ns reverse recovery time for high-frequency operation. Verify thermal resistance requirements against the ambient temperature conditions of the target application environment.
Part Context
This component belongs to the BYV26x series of ultra-fast avalanche sinterglass diodes from Vishay Semiconductors. The series includes variants with different reverse voltage ratings, such as BYV26B (400 V), BYV26C (600 V), BYV26D (800 V), and BYV26E (1000 V). All variants share the same 1 A average forward current rating and similar physical package dimensions.
Replacement Considerations
Direct substitutes within the same family include BYV26B-TR, BYV26C-TR, BYV26D-TR, and BYV26E-TR, which offer higher reverse voltage ratings while maintaining identical current and package specifications.
