1N5366AE3/TR12

Overview

The Microchip Technology 1N5366AE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 39 V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 500 nA at 28.1 V and a dynamic impedance of 14 Ohms. The device utilizes an axial-lead T-18 package and includes a TR suffix for tape and reel packaging.

Feature Summary

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

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation

Procurement Notes

Verify the component against official datasheets to confirm electrical parameters and physical dimensions. Ensure compatibility with existing thermal management designs due to the 5-watt power dissipation rating. Confirm that the tape and reel packaging meets specific manufacturing handling requirements.

Selection Notes

Select this component when a precise 39 V reference or regulation point is required in high-power environments. Consider the ±10% tolerance and low dynamic impedance for stability. Evaluate thermal resistance requirements based on the intended mounting method and ambient temperature conditions.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'e3' suffix indicates RoHS compliance, while the 'TR12' designation specifies the tape and reel packaging format. The device is manufactured by Microsemi, now part of Microchip Technology.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference specifications such as voltage, power dissipation, and package type to ensure functional equivalence.
