1N5347AE3/TR12

Overview

The Microsemi Corporation 1N5347AE3/TR12 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, housed in an axial-lead T-18 plastic package with tape and reel packaging. It provides voltage regulation at a nominal Zener voltage of 10 V with a ±10% tolerance (A suffix). The device operates within a temperature range of -65°C to +150°C and features RoHS compliance (e3 suffix). Key electrical characteristics include a maximum dynamic impedance of 2.0 ohms, a test current of 125 mA, and a maximum reverse leakage current of 5.0 µA.

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 changes in voltage versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B with no dry pack required

Applications

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

Procurement Notes

Verify that the part number includes the 'TR' suffix to confirm tape and reel packaging compatibility with automated assembly processes. Confirm the presence of the 'e3' suffix to ensure RoHS compliance status. Check manufacturer documentation for any specific military screening prefixes if higher reliability standards are required for the application environment.

Selection Notes

Select this component when a 10 V regulation point with ±10% tolerance is required in a 5-watt power dissipation scenario. Ensure adequate heat sinking is provided to maintain operation below the maximum thermal limits. Verify that the T-18 axial lead package fits the mechanical constraints of the target printed circuit board layout.

Part Context

This component belongs to the Microsemi 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The 'A' suffix indicates a standard ±10% voltage tolerance, while the 'e3' suffix denotes lead finish and material compliance with environmental directives.

Replacement Considerations

Equivalent parts within the same series include 1N5347B or 1N5347BE3 for identical specifications without the tape and reel packaging.
