1N5373AE3/TR13

Overview

The Microchip Technology 1N5373AE3/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 68 V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial lead T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 44 Ohms and a maximum reverse current of 0.5 µA. It is supplied in tape and reel packaging.

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 circuits requiring 5-watt power dissipation
• High surge stress protection applications
• Equipment requiring non-sensitive ESD performance per MIL-STD-750 Method 1020

Procurement Notes

Verify the component status as this specific part number may be discontinued or subject to change. Confirm that the 'TR' suffix correctly indicates tape and reel packaging and the 'e3' suffix denotes RoHS compliance. Ensure the required tolerance matches the 'A' designation for ±10%. Cross-reference the manufacturer's latest documentation for availability and valid substitute options.

Selection Notes

Select this component when a 68 V Zener voltage with ±10% tolerance is required in a 5-watt axial package. Consider the thermal resistance of 25 °C/W junction-to-lead for heat sinking requirements. Verify that the maximum regulator current and surge current ratings align with the circuit's peak load conditions. Ensure the operating temperature range meets the environmental demands of the application.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliant tin plating, while the 'TR' suffix specifies tape and reel packaging for automated assembly processes.
