Overview
The BYV98-50-TAP is an ultra-fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 50 V and an average forward current rating of 4 A in the SOD-64 axial package. The device exhibits a low reverse recovery time of 35 ns, a maximum forward voltage drop of 1.1 V at 5 A, and a non-repetitive reverse avalanche energy capability of 20 mJ. Operating temperatures range from -55 °C to +175 °C.
Feature Summary
- Ultra-fast switching performance with low reverse recovery time
- Avalanche-rated for robust energy handling
- Hermetically sealed glass passivated envelope
- Low forward voltage drop
Applications
- Switched mode power supplies
- High-frequency inverter circuits
Procurement Notes
Verify that the specific ordering code matches the required tape and reel or ammopack configuration. Confirm the exact reverse voltage rating aligns with circuit requirements, as this part number corresponds to the 50 V variant within the broader BYV98 series. Ensure thermal management meets the specified junction temperature limits during operation.
Selection Notes
Select this component when high-speed rectification and avalanche ruggedness are required in through-hole designs. The SOD-64 package provides a compact solution for high-frequency applications. Consider the 4 A average current limit and 70 A surge capability when sizing for load conditions.
Part Context
This component belongs to the BYV98 family of ultra-fast sinterglass diodes produced by Vishay Semiconductors. The series includes variants with different reverse voltage ratings (50 V, 100 V, 150 V, and 200 V), all sharing identical current ratings and physical packaging characteristics for consistent design integration.
