1N4752A-T

Overview

The Diodes Incorporated 1N4752A-T is a discontinued 1.0W Zener diode with a nominal voltage of 33V and a standard tolerance of ±5%. It utilizes a DO-41 glass package for through-hole mounting. The device operates within a temperature range of -65°C to +175°C, featuring a maximum reverse leakage current of 5.0µA at 25.1V and a Zener impedance of 45Ω at the test current of 7.5mA.

Feature Summary

• Provides stable voltage regulation in clipping and stabilizing circuits
• Constructed with a hermetically sealed glass passivated junction
• Features lead-free finish compliant with RoHS directives

Applications

• Voltage stabilization circuits
• Signal clipping applications
• General-purpose voltage reference

Procurement Notes

This component is officially marked as obsolete and discontinued by Diodes Incorporated. No alternate part numbers are provided in the datasheet. Procurement must rely on existing stock or secondary market sources, as new production has ceased. Verify authenticity carefully due to potential surplus availability.

Selection Notes

Select this component only if legacy compatibility is required, as it is no longer manufactured. Ensure the design accommodates the specific thermal resistance characteristics of the DO-41 package. Consider redesigning with currently available equivalents from other manufacturers if long-term supply assurance is necessary.

Part Context

The 1N4752A belongs to the 1N4728A through 1N4761A series of 1.0W Zener diodes produced by Diodes Incorporated. This series covers a wide voltage range from 3.3V to 75V. The specific suffix '-T' indicates tape and reel packaging for automated assembly processes.

Replacement Considerations

No official substitute is listed in the datasheet. Designers should consult cross-reference data from other semiconductor manufacturers offering equivalent 1W, 33V Zener diodes in the DO-41 package.
