1N5344CE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5344CE3/TR12 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, designed for voltage regulation from 3.3 to 200 volts. It features a T-18 axial lead package with void-free transfer molded epoxy meeting UL94V-0 flammability ratings. The device operates within a temperature range of -65°C to +150°C and includes RoHS compliance via the e3 suffix and tape & reel packaging via the TR12 suffix.

Single Zener Diodes 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 suitable for through-hole applications

Single Zener Diodes Applications

• Voltage regulation circuits requiring 5-watt power dissipation
• High current applications with adequate heat sinking
• General purpose electronic equipment utilizing axial-lead components

Single Zener Diodes Procurement Notes

Verify the specific part number against official manufacturer documentation to confirm the presence of the 'e3' RoHS compliant and 'TR12' tape & reel suffixes. Ensure that the ordering information matches the exact electrical characteristics and mechanical dimensions required for your design, as suffixes define critical functional and packaging attributes.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and axial lead configuration are necessary. The 'C' suffix indicates a tight ±2% voltage tolerance, which is suitable for precision regulation tasks. Consider the thermal resistance and derating curves if the application involves high ambient temperatures or limited heat sinking capabilities.

Single Zener Diodes Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options defined by suffix letters. These devices are JEDEC registered and designed for robust performance in demanding environments.

Single Zener Diodes Replacement Considerations

Compatible substitutes include other 5-watt Zener diodes from the same series, such as the 1N5343B or 1N5345B, provided they meet the specific voltage and tolerance requirements. Verify that any replacement maintains the same package type and thermal characteristics.
