1N5372AE3/TR13

Overview

The Microchip Technology 1N5372AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 62 V with a ±10% tolerance, indicated by the 'A' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum dynamic impedance of 42 Ohms at a test current of 20 mA, a maximum reverse leakage current of 0.5 µA at 44.6 V, and a maximum regulator current of 2.1 A.

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

Applications

• Voltage regulation in power supply circuits
• Protection against transient voltage spikes
• Reference voltage generation in electronic systems

Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm that the part number matches the specific electrical requirements, including the 62 V Zener voltage and ±10% tolerance. Ensure the RoHS compliant e3 suffix and tape & reel TR packaging are present as specified. Check for any relevant product change notifications or discontinuance statuses before finalizing procurement decisions.

Selection Notes

Select this component when a 5-watt axial Zener diode with a 62 V nominal voltage is required. The ±10% tolerance suits applications where tighter precision is not critical. Consider the thermal resistance and derating curves if operating near maximum power dissipation limits. Verify that the T-18 package dimensions fit the target PCB layout and that the operating temperature range meets environmental constraints.

Part Context

This component belongs to the Microsemi (now Microchip Technology) Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance, while the 'TR' suffix denotes tape and reel packaging. These devices are designed for general-purpose voltage regulation and protection applications.
