BYD33GGP-E3/73

Overview

The BYD33GGP-E3/73 is a general-purpose rectifier diode manufactured by Vishay General Semiconductor - Diodes Division. It features a 400V repetitive peak reverse voltage and a 1A average forward rectified current. The device utilizes glass passivation for electrode isolation, ensuring stability under harsh conditions. It is housed in the DO-204AL (DO-41) axial through-hole package. Key electrical parameters include a maximum forward voltage of 1.2V at 1A and a non-repetitive peak surge current capability of 30A. The component operates within a junction temperature range of -65°C to +175°C.

Feature Summary

• Glass passivated cathode for enhanced environmental stability and reliable performance
• High surge current capability designed to withstand transient overload events
• Axial leaded construction suitable for standard through-hole mounting processes

Applications

• General purpose rectification in power supply circuits
• Reverse polarity protection in electronic assemblies
• DC output rectification in low-power adapters

Procurement Notes

Verify the specific suffix E3/73 to confirm RoHS compliance and packaging type. Confirm that the DO-204AL package dimensions match your PCB footprint requirements. Check current availability status as discrete components may have varying lead times. Ensure the 400V rating meets the peak inverse voltage requirements of your target circuit application.

Selection Notes

Select this component when a robust, cost-effective solution for moderate current rectification is required. The 1A rating suits applications where higher capacity devices are unnecessary. Consider the 175°C junction temperature limit for high-thermal environments. Compare against similar DO-41 rectifiers if alternative sourcing is needed for production continuity.

Part Context

This part belongs to Vishay's lineup of glass-passivated general-purpose rectifiers. These diodes are engineered for durability in industrial and consumer electronics. The DO-204AL package provides a balance between current handling and physical size. This series is widely used in basic power conversion stages requiring reliable blocking characteristics.

Replacement Considerations

Direct substitutes include other 400V 1A axial rectifiers such as the 1N400x series variants or equivalent parts from other manufacturers using the DO-41 package. Verify that replacement parts meet the same 1.2V forward voltage and 30A surge current specifications to ensure circuit compatibility.
