1N5336E3/TR12

Single Zener Diodes Overview

The Microsemi Corporation 1N5336E3/TR12 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333B through 1N5388B series, housed in a T-18 axial leaded plastic package. It provides a nominal Zener voltage of 4.3 V with a standard tolerance of ±5%. The device operates within a temperature range of -65°C to +150°C and features RoHS compliance indicated by the e3 suffix. Packaged in tape and reel format per EIA-296 standards as denoted by the TR12 suffix, it offers low thermal resistance for high DC current operation.

Single Zener Diodes Feature Summary

• Provides stable voltage regulation across broad operating current and temperature ranges
• Features flexible axial-lead mounting terminals suitable for through-hole applications
• Withstands high surge stresses and exhibits minimal changes of voltage versus current
• Non-sensitive to electrostatic discharge (ESD) per MIL-STD-750 Method 1020

Single Zener Diodes Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply reference designs utilizing wide selection of voltages
• Industrial equipment needing high surge stress withstand capability

Single Zener Diodes Procurement Notes

Verify that the component matches the specific 4.3V Zener voltage and ±5% tolerance requirements. Confirm the presence of the e3 suffix for RoHS compliance and the TR12 suffix for tape and reel packaging. Ensure the manufacturer designation aligns with Microsemi specifications before integration into production systems.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power dissipation rating is required alongside precise voltage regulation. Consider the T-18 package dimensions for board layout constraints. Evaluate thermal management needs based on the junction-to-lead thermal resistance characteristics provided in the datasheet for optimal heat sinking design.
