1N5369A/TR12

Overview

The Microchip Technology 1N5369A/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 51V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, features a maximum reverse current of 93µA at 36.7V, and has a dynamic impedance of 27Ω. The device utilizes a T-18 axial lead package and is supplied in tape and reel format.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High surge stress environments
• Broad operating temperature applications

Procurement Notes

Verify the specific suffix 'TR12' against official documentation to confirm tape and reel packaging compliance. Confirm RoHS status as the datasheet indicates both compliant and non-compliant variants exist within this series. Ensure the A suffix corresponds to the required ±10% tolerance for your design specifications.

Selection Notes

Select this component when a 51V Zener reference with ±10% tolerance is required. Consider the 5W power rating and thermal resistance characteristics for heat sinking requirements. Verify that the T-18 axial package fits the PCB layout constraints compared to surface mount alternatives.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers voltages from 3.3V to 200V with various tolerance options identified by suffix letters.

Replacement Considerations

Consult the manufacturer's discontinuance notification or cross-reference guide for verified substitutes. Generic equivalents may not match the specific thermal or electrical characteristics of the original Microsemi part.
