1N5374AE3/TR13

Overview

The Microsemi Corporation 1N5374AE3/TR13 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial T-18 package with a TR suffix for tape and reel packaging. It provides voltage regulation at a standard nominal voltage of 75V with a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum forward voltage of 1.2V at 1.0A. Electrical characteristics include a test current of 20mA, a maximum dynamic impedance of 45 ohms, and a maximum reverse current of 0.5µA tested at 54V.

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 suitable for various heat sinking configurations
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High maximum DC current applications with adequate heat sinking
• Surge stress protection environments

Procurement Notes

Verify that the ordering suffix 'TR' corresponds to the specified tape and reel packaging format as defined by EIA-296 standards. Confirm the component meets RoHS compliance requirements indicated by the 'e3' suffix. Ensure the procurement matches the specific ±10% tolerance designation associated with the 'A' suffix for the 75V rating.

Selection Notes

Select this component when a 75V Zener voltage with ±10% tolerance is required in an axial leaded package. Consider the 5.0-watt power dissipation capability and the thermal resistance specifications for junction-to-lead or junction-to-ambient mounting on FR4 PC boards. Verify compatibility with the T-18 case dimensions and polarity markings before integration.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters. These plastic encapsulated devices are designed for robust performance in demanding electronic applications.

Replacement Considerations

Surface mount equivalents such as SMBJ5374A or SMBG5374A are available within the same product family. Military screening levels can be obtained by adding MQ, MX, or MV prefixes to the base part number.
