Overview
The BY203-16STAP is a fast avalanche sinterglass diode manufactured by Vishay Semiconductors. It features a hermetically sealed SOD-57 package with plated axial leads. The device provides a repetitive peak reverse voltage of 1600 V and an average forward current rating of 0.25 A. Electrical characteristics include a maximum forward voltage of 2.4 V at 0.2 A, a non-repetitive reverse avalanche energy capability of 10 mJ, and a maximum reverse recovery time of 300 ns. The junction temperature range spans from -55 °C to +150 °C.
Feature Summary
- Hermetically sealed glass passivated junction for environmental protection
- Avalanche rated for non-repetitive surge energy absorption
- Fast switching performance suitable for high-frequency applications
Applications
- TV-line output circuits
- Switch mode power supplies
Procurement Notes
Verify the specific ordering code BY203-16STAP against official Vishay documentation to confirm the ammopack packaging configuration. Ensure that the 1600 V reverse voltage rating aligns with the circuit requirements. Confirm compliance with material categorization definitions provided in the datasheet before finalizing procurement specifications.
Selection Notes
Select this component when a high-voltage, fast-switching rectifier with avalanche capability is required in a compact axial leaded package. The SOD-57 form factor supports through-hole mounting. Evaluate thermal resistance parameters relative to the expected ambient temperature and forward current load to ensure operation within the specified junction temperature limits.
Part Context
This part belongs to the BY203 series of fast avalanche sinterglass diodes produced by Vishay Semiconductors. The series includes variants with different reverse voltage ratings, such as 1200 V and 2000 V options. All members share the same SOD-57 package style and general electrical architecture designed for robust rectification and switching tasks.
Replacement Considerations
Direct substitutes must match the 1600 V rating, 0.25 A current capacity, and SOD-57 package dimensions. Verify that alternative components also possess avalanche energy ratings if surge protection is critical to the application design.
