1N5336BE3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5336BE3/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 4.3V and a ±5% tolerance. It operates within a temperature range of -65°C to +150°C and features a T-18 axial lead package. The device provides stable voltage regulation across a broad operating current range, withstands high surge stresses, and exhibits minimal voltage changes versus current. It is RoHS compliant and designed for applications requiring flexible mounting terminals.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation over a broad operating current and temperature range
• Withstands high surge stresses and is nonsensitive to ESD per MIL-STD-750 Method 1020
• Features flexible axial-lead mounting terminals for versatile installation

Single Zener Diodes Procurement Notes

Verify the specific suffixes (e.g., BE3/TR12) against official datasheets to confirm exact electrical tolerances, packaging format, and compliance status. Confirm availability and obsolescence status directly with the manufacturer or authorized distributors before procurement.

Single Zener Diodes Selection Notes

Select this component for applications requiring a 4.3V Zener voltage with a 5W power dissipation rating. Ensure adequate heat sinking is provided to maintain performance at maximum DC currents. Verify that the T-18 axial lead package fits the mechanical constraints of the target design.

Single Zener Diodes Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0-watt Zener diodes. 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 high reliability and robust operation in demanding environments.

Single Zener Diodes Replacement Considerations

Surface mount equivalents such as SMBJ5333 to SMBJ5388B or SMBG5333B to SMBG5388B are available. Military equivalent screening levels can be obtained by adding MQ, MX, or MV prefixes to the part numbers.
