Overview
The BYV98-50-TR is an ultra-fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a 50 V repetitive peak reverse voltage and supports a 4 A average forward current in the SOD-64 axial leaded package. The device exhibits a maximum forward voltage of 1.1 V at 5 A, with a low reverse current of 10 µA at rated voltage. Key electrical parameters include a 70 A peak forward surge current capability and a reverse recovery time of 35 ns. It operates within a junction temperature range of -55 °C to +175 °C.
Feature Summary
- Ultra-fast avalanche performance for high-frequency switching applications
- Hermetically sealed glass passivated axial-leaded envelope
- Low reverse current and low forward voltage drop characteristics
Applications
- Switched mode power supplies
- High-frequency inverter circuits
Procurement Notes
Verify the specific ordering code suffix against official documentation to confirm packaging format. Confirm that the component meets required RoHS compliance standards for your region. Validate thermal resistance values under actual mounting conditions before finalizing design specifications.
Selection Notes
Select this component when a 50 V rating is required alongside ultra-fast recovery speeds. Ensure the circuit design accommodates the 70 A surge current limit during transient events. Verify that the SOD-64 package dimensions fit the intended PCB layout constraints.
Part Context
This part belongs to the BYV98 series of ultra-fast avalanche sinterglass diodes from Vishay. The series includes variants with different reverse voltage ratings, such as 100 V, 150 V, and 200 V options. All variants share identical physical packages and general electrical characteristics except for their specific breakdown voltage thresholds.
Replacement Considerations
Direct substitutes within the same Vishay family include BYV98-100-TR, BYV98-150-TR, and BYV98-200-TR. These parts maintain identical package and current ratings but offer higher reverse voltage capabilities.
