BY133GP-E3/73

Overview

The BY133GP-E3/73 is a standard recovery rectifier manufactured by Vishay General Semiconductor - Diodes Division. It features a glass passivated junction and is housed in the DO-204AC (DO-15) axial leaded package. The device is rated for a maximum repetitive peak reverse voltage of 1300 V and an average forward rectified current of 1 A. It complies with RoHS standards and is marked as obsolete.

Feature Summary

• Glass passivated junction construction
• High voltage blocking capability
• Axial through-hole mounting

Applications

• General purpose rectification
• Power supply circuits
• Inverter freewheeling diodes

Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability requires checking distributor stock status directly, as new production is discontinued. Sourcing should focus on surplus inventory or qualified replacement alternatives that match the electrical specifications and package dimensions.

Selection Notes

Select this part only if legacy compatibility with the DO-204AC package and 1300V rating is required. Designers must account for its obsolete status when planning long-term production cycles. Ensure thermal management aligns with the 1A continuous current rating and verify that the standard recovery speed meets the application's switching frequency requirements.

Part Context

The BY133 series belongs to Vishay's general-purpose rectifier lineup designed for high-voltage applications. These devices utilize glass passivation to protect the silicon junction against mechanical stress and moisture. The GP suffix indicates the specific plastic axial packaging variant within the broader BY133 family.
