Overview
The BYW83TAP is a single avalanche diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 400 V and an average forward rectified current of 3 A. The device utilizes a through-hole SOD-64 axial package. Key electrical characteristics include a non-repetitive peak forward surge current (IFSM) of 100 A and a standard recovery speed exceeding 500 ns with currents greater than 200 mA. The component is designed for robust performance in power management applications.
Feature Summary
- Avalanche rated capability for energy absorption
- Through-hole axial mounting configuration
- Standard recovery speed classification
Applications
- Power supply rectification circuits
- Flyback diode protection in inductive loads
- General purpose power management systems
Procurement Notes
Verify the specific suffix 'TAP' corresponds to the required packaging format, typically cut tape or ammo pack, as indicated by distributor listings. Confirm RoHS compliance status and lead-free designation against the latest manufacturer datasheet before integration. Ensure the SOD-64 axial package dimensions match the target PCB footprint requirements for proper mechanical assembly.
Selection Notes
Select this component when a through-hole solution is required for high-current rectification up to 3 A. The 400 V rating suits medium-voltage AC/DC conversion stages. Consider the standard recovery time for general-purpose switching rather than high-frequency applications. The avalanche rating provides additional resilience against transient voltage spikes compared to standard rectifiers.
Part Context
This part belongs to Vishay's single diode portfolio, specifically within the avalanche-rated segment. It serves as a discrete semiconductor solution for power electronics, distinct from integrated modules. The SOD-64 package offers a compact axial form factor suitable for legacy or space-constrained through-hole designs requiring reliable current handling.
Replacement Considerations
Cross-reference with other Vishay avalanche diodes in the SOD-64 package if availability is constrained. Verify that substitute parts maintain the 400 V reverse voltage and 3 A current ratings. Ensure equivalent surge current capabilities and recovery speeds to prevent circuit performance degradation.
