1N5347BE3/TR12

Overview

The Microsemi Corporation 1N5347BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, housed in an axial-leaded T-18 package with tape and reel packaging. It provides a nominal Zener voltage of 10 V with a ±5% tolerance. The device operates within a temperature range of -65°C to +150°C and features a maximum dynamic impedance of 2.0 ohms at a test current of 125 mA. It includes RoHS compliance indicated by the e3 suffix.

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 for secure installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Protection against transient voltage spikes
• Reference voltage generation in electronic systems

Procurement Notes

Verify the specific ordering suffixes to confirm the presence of the TR (Tape & Reel) option and the e3 (RoHS Compliant) designation. Confirm that the component matches the standard JEDEC registration requirements for the 1N5347B series. Ensure the procurement documentation aligns with the manufacturer's specifications for the T-18 plastic encapsulated case.

Selection Notes

Select this component when a 10 V Zener voltage with ±5% tolerance is required for 5-watt applications. Consider the T-18 axial lead package for through-hole mounting. Evaluate thermal resistance characteristics, specifically the 25 °C/W junction-to-lead rating, to ensure adequate heat sinking for high DC currents. Verify compatibility with the specified operating temperature range.

Part Context

This part 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 to 200 volts. The 1N5347B variant specifically targets the 10-volt regulation segment within this robust family of plastic encapsulated devices designed for general-purpose voltage regulation tasks.

Replacement Considerations

Surface mount equivalents are available as SMBJ5347 or SMBG5347. Military screening options include MQ1N5347BE3, MX1N5347DE3, and MV1N5347BE3.
