Overview
The BYT54D-TR is a fast avalanche sinterglass diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and a maximum average forward rectified current of 1.25 A. The component utilizes the SOD-57 surface-mount package. It is characterized by fast recovery times less than or equal to 500 ns and supports peak forward surge currents exceeding 200 mA.
Feature Summary
- Fast avalanche sinterglass construction for robust performance
- High-speed recovery characteristics suitable for efficient switching applications
- Compact SOD-57 surface-mount packaging for space-constrained designs
Applications
- Power supply circuits
- General-purpose rectification in electronic systems
- Fast switching applications requiring avalanche capability
Procurement Notes
Verify the specific suffix against official Vishay documentation to confirm package type and tape/reel specifications. Ensure the procurement channel provides valid manufacturer traceability. Confirm that the received components match the exact part number designation to avoid compatibility issues with circuit design requirements.
Selection Notes
Select this component when a 200 V reverse voltage rating and 1.25 A continuous current capacity are required in a compact surface-mount form factor. The fast recovery time makes it suitable for high-frequency applications. Consider the SOD-57 footprint constraints during PCB layout planning to ensure proper thermal and electrical performance.
Part Context
This device belongs to the BYT54 series of fast avalanche sinterglass diodes from Vishay. The series includes variants with different voltage ratings, such as the BYT54A (50 V) and BYT54B (100 V), all sharing the same 1.25 A current rating and SOD-57 package. The 'TR' suffix typically indicates tape and reel packaging for automated assembly processes.
Replacement Considerations
Direct substitutes within the same Vishay family include BYT54A-TR and BYT54B-TR, provided the lower voltage ratings meet the circuit requirements. Cross-manufacturer replacements must be verified for matching voltage, current, and package dimensions.
