1N5372E3/TR13

Overview

The Microchip Technology 1N5372E3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333 to 1N5388B series. It provides voltage regulation at a nominal Zener voltage of 62 volts with a standard tolerance of plus or minus 5 percent, indicated by the B suffix. The device features an axial-lead T-18 package and operates within a temperature range of -65°C to +150°C. It includes RoHS compliance via the e3 suffix and tape-and-reel packaging options denoted by the TR suffix.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• Compliant with RoHS standards and moisture classification Level 1

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in electronic systems

Procurement Notes

Verify that the ordering suffix matches the required specifications: 'e3' confirms RoHS compliance, while 'TR' indicates tape-and-reel packaging. Confirm the 'B' suffix corresponds to the necessary ±5% voltage tolerance. Ensure the manufacturer designation aligns with Microchip Technology's acquisition of the original Microsemi Scottsdale Division product line before finalizing procurement orders.

Selection Notes

Select this component when a 62-volt regulation point is required with a 5-watt power rating. The axial lead configuration suits through-hole mounting applications. Consider the thermal resistance characteristics and derating curves if operating near maximum ambient temperatures. Verify that the specific tolerance and packaging format meet the design requirements.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally manufactured by Microsemi's Scottsdale Division. The series covers a wide voltage selection from 3.3 to 200 volts. Microchip Technology now produces these devices following its acquisition of Microsemi, maintaining the established JEDEC registration and mechanical specifications.

Replacement Considerations

Direct equivalents include other manufacturers' 1N5372B axial-lead Zener diodes meeting the same 5-watt and 62-volt specifications. Surface mount alternatives such as the SMBJ5372BE3 series offer similar electrical performance in a different package form factor.
