BYT52K-TR

Overview

The BYT52K-TR is an avalanche rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage of 800 V and an average forward current rating of 1.4 A. The device utilizes SOD-57 axial through-hole packaging. Key electrical characteristics include a maximum forward voltage of 1.3 V at 1 A and a reverse leakage current of 5 µA at 800 V. The component supports a junction operating temperature range from -55°C to 175°C and exhibits a reverse recovery time of 200 ns.

Feature Summary

• Incorporates avalanche technology for robust performance under high-voltage conditions
• Designed for fast recovery applications with specified switching characteristics
• Constructed in a compact SOD-57 axial package suitable for through-hole mounting

Applications

• High-voltage power supply circuits
• Fast recovery rectification tasks
• General-purpose discrete semiconductor applications requiring avalanche capability

Procurement Notes

Verify the specific suffix K against official Vishay documentation to confirm exact parameter tolerances and manufacturing lot details. Confirm RoHS3 compliance status directly with the manufacturer datasheet prior to integration. Ensure the SOD-57 axial package dimensions match the target PCB layout requirements. Validate that the 800 V reverse voltage rating aligns with the circuit's peak inverse voltage demands.

Selection Notes

Select this component when an 800 V blocking capability is required alongside a 1.4 A continuous current rating. The SOD-57 package is appropriate for designs utilizing through-hole assembly processes. Consider the 200 ns reverse recovery time for frequency constraints. Verify thermal management capabilities given the 175°C maximum junction temperature limit.
