1N5347BE3/TR13

Overview

The Microsemi Corporation 1N5347BE3/TR13 is a silicon Zener diode from the JEDEC registered 1N5333B-1N5388B series. It provides voltage regulation at a nominal Zener voltage of 10 V with a standard tolerance of ±5%. The device features a T-18 axial lead package and supports a maximum power dissipation of 5.0 watts. Electrical characteristics include a test current of 125 mA, a maximum dynamic impedance of 2.0 ohms, and a maximum reverse current of 5.0 µA. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification Level 1 requiring no dry pack storage

Applications

• Voltage regulation in power supply circuits
• Reference voltage generation for electronic systems
• Overvoltage protection applications

Procurement Notes

Verify that the ordering suffix TR13 corresponds to the tape and reel packaging option as specified by EIA-296 standards. Confirm RoHS compliance status associated with the e3 suffix. Ensure the component matches the T-18 axial lead package dimensions and verify the manufacturer designation aligns with Microsemi specifications before procurement.

Selection Notes

Select this component when a 10 V reference with ±5% tolerance is required in an axial lead format. Consider the 5-watt power dissipation capability and thermal resistance characteristics for heat sinking requirements. Evaluate the maximum dynamic impedance and reverse leakage current against circuit sensitivity needs. Verify compatibility with the intended PCB mounting style and ambient operating temperatures.

Part Context

This part belongs to the 1N5333B-1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages ranging from 3.3 V to 200 V. These devices are designed for applications requiring high specified maximum currents and robust performance under varying thermal conditions.

Replacement Considerations

Surface mount equivalents such as SMBJ5347 or SMBG5347 are available within the same product family. Verify pinout compatibility and thermal management requirements when transitioning between axial lead and surface mount packages.
