Overview
The BYT53D-TR is a single ultra-fast avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum repetitive peak reverse voltage of 200 V and an average forward rectified current of 1.9 A. The device utilizes a through-hole SOD-57 package. Key electrical characteristics include a very fast recovery time, with specific documentation citing a reverse recovery time (trr) of 50 ns for the BYT53D series. It is designed for high-speed switching applications requiring avalanche capability.
Feature Summary
- Ultra-fast switching performance suitable for high-frequency circuits
- Avalanche rated for robust operation in inductive load environments
- Sinterglass construction for enhanced thermal stability
Applications
- High-speed rectification in power supplies
- Free-wheeling diodes for inductive loads
- Snubber circuits in switching regulators
Procurement Notes
Verify the exact datasheet version from Vishay to confirm the reverse recovery time specification, as sources vary between 50 ns and other values. Ensure the SOD-57 through-hole package matches your PCB footprint requirements. Confirm RoHS compliance status if required for your manufacturing process. Cross-reference the part number suffix TR to ensure tape-and-reel packaging if applicable.
Selection Notes
Select this component when a 200 V reverse voltage rating and 1.9 A continuous current are required. The avalanche capability makes it suitable for applications with potential voltage spikes. Compare the 50 ns reverse recovery time against slower standard diodes if switching speed is critical. Ensure the through-hole SOD-57 package is compatible with your assembly method.
Part Context
The BYT53D-TR belongs to the BYT53 series of ultra-fast silicon mesa rectifiers. This series includes variants with different reverse voltage ratings, such as the BYT53C (150 V). The 'D' suffix typically denotes the 200 V rating. These diodes are engineered for efficiency in modern power conversion systems where low loss and fast response are necessary.
Replacement Considerations
Check for direct substitutes within the BYT53 series, such as BYT53C-TR for lower voltage applications. Verify that any replacement maintains the 1.9 A current rating and 200 V blocking capability. Ensure the replacement also supports avalanche operation if your circuit design relies on this feature.
