1N5334BE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5334BE3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B to 1N5388B series, housed in an axial-lead T-18 package with tape and reel packaging. It provides a nominal Zener voltage of 3.6 V at a test current of 350 mA, featuring a maximum dynamic impedance of 2.5 ohms and a reverse leakage current of 150 µA at 1.0 V. The device supports a maximum regulator current of 1320 mA and withstands surge currents up to 500 A. It operates within a temperature range of -65°C to +150°C.

Single Zener Diodes 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 changes versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B without requiring dry pack

Single Zener Diodes Applications

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

Single Zener Diodes Procurement Notes

Verify that the part number includes the 'e3' suffix to confirm RoHS compliance and the 'TR' suffix to ensure tape and reel packaging. Confirm the manufacturer as Microsemi Corporation or its successor entity. Check datasheet revisions for updated thermal derating curves and electrical characteristics before finalizing procurement specifications.

Single Zener Diodes Selection Notes

Select this component when a 3.6 V regulation point is required with a 5 W power dissipation capability. Ensure adequate heat sinking is provided to maintain junction temperatures within limits during high DC current operation. Verify that the ±5% tolerance aligns with circuit requirements and that the T-18 package dimensions fit the available board space.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi's Scottsdale Division. The series offers a wide selection of voltages from 3.3 V to 200 V with various tolerance options identified by specific suffix letters. These plastic encapsulated devices are designed for applications requiring robust performance under high surge stresses.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333B to SMBJ5388B or SMBG5333B to SMBG5388B are available from the same manufacturer. For military equivalent screening levels, prefixes MQ, MX, or MV can be added to part numbers to obtain JAN, JANTX, or JANTXV variants respectively.
