1N5373CE3/TR13

Overview

The Microchip Technology 1N5373CE3/TR13 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 68 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in an axial lead DO-41 package and is supplied in tape and reel format, denoted by the 'TR13' suffix. Key electrical characteristics include a maximum dynamic impedance of 44 ohms and a maximum reverse current of 0.5 µA. It withstands high surge stresses and features a moisture classification of Level 1.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• RoHS compliant construction with void-free transfer molded thermosetting epoxy body

Applications

• Voltage regulation in power supply circuits
• Reference voltage sources for electronic instrumentation
• Overvoltage protection for sensitive semiconductor components

Procurement Notes

Verify that the ordering suffix includes both 'e3' for RoHS compliance and 'TR13' for tape and reel packaging. Confirm the 'C' suffix corresponds to the required ±2% voltage tolerance. Ensure the procurement specification matches the 1N5373B base part number within the 1N5333-5388B series to guarantee correct 68V rating and 5W power dissipation capabilities.

Selection Notes

Select this component when a precise 68V reference with ±2% accuracy is required in a 5-watt axial package. The tape and reel option facilitates automated surface or through-hole assembly processes. Consider the thermal resistance of 25°C/W junction-to-lead for heat sinking requirements. Verify compatibility with systems requiring Level 1 moisture sensitivity classification without dry pack 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 offers a wide selection of voltages from 3.3V to 200V. The specific 1N5373 variant targets applications needing 68V regulation. The e3 suffix indicates lead finish compliance, while TR13 denotes industrial tape and reel packaging standards.

Replacement Considerations

Surface mount equivalents are available as SMBJ5373 or SMBG5373. Military screening options exist with MQ, MX, or MV prefixes. Other tolerances are available via A (±10%), C (±2%), or D (±1%) suffixes.
