1N5372A/TR8

Overview

The Microchip Technology 1N5372A/TR8 is a silicon 5.0-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 400 µA at 44.6 V and a dynamic impedance of 42 Ω at a test current of 20 mA. The device utilizes a T-18 axial lead package and includes a tape and reel option indicated by the TR suffix.

Feature Summary

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

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm availability status and exact electrical tolerances. Ensure that the ordering suffix matches the required packaging format and compliance specifications before finalizing procurement orders.

Selection Notes

Select this component when a 62 V reference with moderate precision is required in a through-hole configuration. Consider the thermal resistance characteristics and derating curves if the application involves continuous operation near the maximum power dissipation limit.

Part Context

This device belongs to the 1N5333B thru 1N5388B series of JEDEC registered silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3 V to 200 V in a standardized 5-watt plastic encapsulated package suitable for general-purpose industrial applications.

Replacement Considerations

Consult official datasheets for cross-reference data regarding equivalent parts from other manufacturers. Verify mechanical dimensions and pinout compatibility before substituting.
