1N5372AE3/TR8

Overview

The Microchip Technology 1N5372AE3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 62 V and ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 500 nA at 44.6 V and a dynamic impedance of 42 Ohms. The component utilizes an axial-lead T-18 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 voltage change versus current
• Features flexible axial-lead mounting terminals for secure installation

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress environments
• Equipment needing wide temperature stability from -65°C to +150°C

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance and packaging details. Ensure compatibility with thermal management requirements for 5-watt operation. Confirm RoHS compliance status through manufacturer documentation before integration into final assemblies.

Selection Notes

Select this component when a 62 V reference with ±10% tolerance is required. Consider the T-18 axial package for through-hole applications. Evaluate thermal resistance characteristics relative to the intended heat sinking method to ensure safe steady-state power dissipation limits are not exceeded.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while the 'TR8' designation specifies the tape-and-reel packaging format.

Replacement Considerations

Equivalent parts include the 1N5372B (±5% tolerance) or 1N5372 (±20% tolerance). Surface mount alternatives are available as SMBJ5372B or SMBG5372B.
