1N5346E3/TR13

Overview

The Microchip Technology 1N5346E3/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 9.1V with a ±10% tolerance, indicated by the 'A' suffix in the base part number. 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 2.0 Ohms and a maximum reverse current of 7.5 µA.

Feature Summary

Provides stable voltage regulation across a broad operating current and temperature range
Features flexible axial-lead mounting terminals for versatile integration
Withstands high surge stresses and exhibits minimal voltage change versus current
Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

Voltage regulation in power supply circuits
Overvoltage protection for sensitive electronic components
Reference voltage sources in measurement equipment

Procurement Notes

Verify the specific suffix configuration against the datasheet to ensure correct voltage tolerance and RoHS compliance. Confirm that the TR suffix indicates tape and reel packaging as specified in the mechanical data. Cross-reference the manufacturer's official documentation for any updates regarding screening levels or equivalent military specifications.

Selection Notes

Select this component when a 5-watt power dissipation rating and a 9.1V Zener voltage are required. Ensure adequate heat sinking is provided to maintain operation within the specified thermal resistance limits. Consider the axial lead format for through-hole mounting requirements and verify compatibility with the system's operating temperature range.

Part Context

This component belongs to the 1N5333-5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). 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 applications requiring robust voltage regulation and high surge current handling capabilities.
