1N5372E3/TR8

Overview

The Microchip Technology 1N5372E3/TR8 is a silicon 5-watt Zener diode with a nominal voltage of 62 V and ±5% 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 includes the 'e3' suffix for RoHS compliance and 'TR' 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 change versus current
• Features flexible axial-lead mounting terminals in a void-free transfer molded epoxy body

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High surge stress environments
• Applications needing ESD resistance per MIL-STD-750 Method 1020

Procurement Notes

Verify the specific part number against official Microchip documentation to confirm RoHS compliance and tape-and-reel configuration. Ensure that the thermal management design accounts for the specified junction-to-lead thermal resistance when operating near maximum power dissipation limits.

Selection Notes

Select this component for applications requiring a 62 V Zener reference with tight ±5% tolerance. Consider the T-18 through-hole package for mechanical stability and verify that the circuit can handle the specified maximum regulator current without exceeding thermal limits.

Part Context

This device belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V, providing engineers with standardized options for various power regulation needs.

Replacement Considerations

Compatible surface mount equivalents are available as SMBJ5372BE3 or SMBG5372BE3. Verify pinout compatibility and thermal performance differences when transitioning between axial-lead and surface mount packages.
