1N5343CE3/TR13

Single Zener Diodes Overview

The Microchip Technology 1N5343CE3/TR13 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 volts with a tight tolerance of ±2%, indicated by the 'C' suffix. The device operates in an axial DO-201 package and features RoHS-compliant tin plating, denoted by the 'e3' suffix. It is supplied in tape and reel packaging, specified by the 'TR13' suffix, suitable for automated assembly processes.

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
• 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 sources in measurement equipment

Single Zener Diodes Procurement Notes

Verify that the ordering suffix matches the required specifications: 'C' for ±2% tolerance, 'e3' for lead-free compliance, and 'TR13' for tape and reel packaging. Confirm the manufacturer designation as Microchip Technology or its predecessor entity to ensure component authenticity and traceability.

Single Zener Diodes Selection Notes

Select this component when a 5-watt power rating and a 7.5-volt regulated output are required. The ±2% tolerance makes it suitable for precision applications compared to standard 5% variants. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits.
