BYD33DGP-E3/73

Overview

The BYD33DGP-E3/73 is a standard recovery rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a maximum DC reverse voltage (Vr) of 200 V and an average rectified current (Io) of 1 A. The device utilizes glass passivation for electrode isolation and is housed in the DO-204AC (DO-15) axial through-hole package. It operates within a junction temperature range of -55°C to +175°C and complies with RoHS 3 standards.

Feature Summary

• Glass passivated cathode for reliable operation under harsh conditions
• High thermal stability supporting extended junction temperature ranges
• Axial leaded construction suitable for through-hole mounting

Applications

• General purpose rectification in power supplies
• DC-DC converter circuits
• Battery charging systems

Procurement Notes

This component is officially marked as obsolete and no longer manufactured by Vishay. Verification of availability should focus on distributor surplus stock or authorized replacement part numbers. Confirm that any sourced units match the original DO-204AC package dimensions and electrical specifications to ensure compatibility with existing designs.

Selection Notes

Select this component only if legacy design constraints require the specific 200 V, 1 A rating and DO-15 package. Due to its obsolete status, engineers should evaluate modern equivalents from the same manufacturer or other vendors that offer active production status while maintaining identical pinout and performance characteristics.

Part Context

The BYD33DGP-E3/73 belongs to Vishay's general-purpose rectifier lineup, designed for applications requiring robust standard recovery characteristics. It is part of the broader BYD series, which provides various voltage and current ratings in standardized packages to support diverse industrial and consumer electronics requirements.
