1N332RB

Single Zener Diodes Overview

The 1N332RB is a high-power Zener diode manufactured by Microsemi Corporation, designed for robust voltage regulation in demanding environments. It features a nominal Zener voltage of 51 V and a maximum power dissipation rating of 50 W. The component utilizes a DO-5 (DO-203AB) stud mount package, which facilitates efficient thermal management through direct mounting to heatsinks. This hermetically sealed metal-glass construction ensures reliability under harsh conditions.

Single Zener Diodes Feature Summary

• Hermetically sealed metal-glass housing for environmental protection
• Stud mount configuration for effective thermal dissipation
• High power handling capability for stable voltage regulation

Single Zener Diodes Applications

• High-power voltage reference circuits
• Industrial power supply regulation
• Harsh environment electronic systems

Single Zener Diodes Procurement Notes

Verify the manufacturer origin, specifically Microsemi or its successors, as multiple vendors list this part. Confirm the package type is DO-5 stud mount and check for specific suffixes indicating tolerance or testing levels. Ensure documentation matches the 51V/50W specifications to avoid confusion with similar series parts like 1N3329.

Single Zener Diodes Selection Notes

Select this component when a 51 V reference with 50 W dissipation is required in a ruggedized application. The DO-5 stud package necessitates appropriate mechanical mounting hardware and thermal interface materials. Consider the hermetic seal requirement if the operating environment involves moisture, vibration, or extreme temperatures where standard plastic packages would fail.

Single Zener Diodes Part Context

This device belongs to the 1N33xx series of high-power Zener diodes produced by Microsemi. These components are characterized by their glass-passivated chips assembled in robust, hermetically sealed housings. The series is engineered for applications requiring high reliability and significant power handling capabilities beyond standard discrete diodes.

Single Zener Diodes Replacement Considerations

Cross-reference with other manufacturers offering DO-5 50W Zener diodes at 51V. Verify that any substitute maintains the same hermetic sealing standard and stud mount dimensions to ensure compatibility with existing thermal and mechanical designs.
