1N5343CE3/TR12

Single Zener Diodes Overview

The Microchip Technology 1N5343CE3/TR12 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 7.5 V with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates within a temperature range of -65°C to +150°C and features an axial lead T-18 package. Electrical characteristics include a maximum reverse current of 10 µA and a dynamic impedance of 1.5 Ohms.

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 applications
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• RoHS compliant construction with void-free transfer molded thermosetting epoxy body

Single Zener Diodes Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply reference designs
• Protection against overvoltage conditions in industrial equipment

Single Zener Diodes Procurement Notes

Verify the specific ordering suffixes to confirm compliance requirements and packaging format. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies tape and reel packaging. Ensure that the component meets all relevant environmental standards required for your specific application before procurement.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and a 7.5 V Zener voltage are required. The ±2% tolerance offers tighter precision than standard B-suffix devices. Consider the thermal resistance and derating curves if operating near maximum power limits or in enclosed environments.

Single Zener Diodes Part Context

This part belongs to the Microsemi (now Microchip) 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage range from 3.3V to 200V. The 'e3' designation confirms lead finish compliance, and the 'TR' suffix denotes availability in tape and reel format for automated assembly.

Single Zener Diodes Replacement Considerations

Compatible substitutes within the same series include 1N5343B, 1N5343BE3, and 1N5343CE3. Verify that any replacement maintains the 5W power rating, T-18 package dimensions, and ±2% voltage tolerance.
