1N5367AE3/TR8

Overview

The Microchip Technology 1N5367AE3/TR8 is a silicon 5.0-watt Zener diode with a nominal voltage of 43V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum dynamic impedance of 20 ohms and a maximum reverse current of 500 nA. The component utilizes an axial-lead T-18 package and is supplied in tape and reel format.

Feature Summary

• Provides stable voltage regulation across broad operating currents and temperatures
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole applications

Applications

• Voltage regulation over broad operating ranges
• High surge stress environments
• Through-hole circuit assembly

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and compliance status. Confirm that the TR8 designation aligns with the required tape and reel packaging specifications for automated assembly processes before finalizing procurement orders.

Selection Notes

Select this component when a 43V reference with moderate precision is required. Ensure adequate heat sinking is provided to maintain performance at maximum DC currents. Verify thermal resistance requirements against the specific PCB copper pad dimensions and track width used in the design.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide voltage selection from 3.3V to 200V with various tolerance options identified by suffix letters. The e3 suffix indicates RoHS compliance, while the TR8 suffix specifies the tape and reel packaging format.

Replacement Considerations

Surface mount equivalents are available as SMBJ5333B through SMBJ5388B or SMBG5333B through SMBG5388B.
