Overview
The BYW52-TR is a standard avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a repetitive peak reverse voltage of 200 V and an average forward current rating of 2 A. The device is housed in the SOD-57 surface-mount package. Key electrical specifications include a maximum forward voltage of 1 V at 1 A and a maximum forward surge current of 50 A. It operates within a standard temperature range typical for general-purpose rectifiers.
Feature Summary
- Utilizes sinterglass construction for robust avalanche characteristics
- Designed for standard recovery applications in surface-mount configurations
- Provides high surge current capability for transient protection
Applications
- General-purpose rectification in consumer electronics
- Protection circuits requiring avalanche withstand capability
- Power supply input stages
Procurement Notes
Verify the specific suffix '-TR' confirms tape-and-reel packaging when sourcing. Confirm RoHS compliance status with the supplier, as historical batches may vary. Ensure the SOD-57 footprint matches your PCB design constraints. Cross-reference the datasheet revision date to ensure parameter accuracy against your design requirements.
Selection Notes
Select this component when a 200 V reverse voltage rating and 2 A continuous current are required in a compact SOD-57 package. Consider the avalanche rating if the application involves inductive load switching or transient voltage suppression. Evaluate the 1 V forward voltage drop against efficiency requirements compared to Schottky alternatives.
Part Context
This part belongs to Vishay's standard avalanche diode lineup, distinct from their Zener series like the BZX384. It serves as a rugged rectifier option where standard recovery speed is sufficient. The SOD-57 package offers a balance between current handling and board space savings compared to through-hole DO-204AH variants.
Replacement Considerations
Direct substitutes must match the 200 V / 2 A / SOD-57 specification. Verify equivalent avalanche ratings if used in clamping applications. Generic 2A 200V rectifiers in SOD-57 may lack the specific sinterglass avalanche durability documented for this Vishay part.
