1N5348C/TR12

Overview

The Microchip Technology 1N5348C/TR12 is a silicon 5.0-watt Zener diode with a nominal voltage of 11 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 5.0 µA at 8.0 V and a dynamic impedance of 2.5 Ω. The device utilizes a T-18 axial lead package and is supplied in tape and reel format.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Features flexible axial-lead mounting terminals for through-hole integration

Applications

• Voltage regulation circuits requiring tight tolerance stability
• High power dissipation applications with adequate heat sinking
• Surge protection environments demanding robust component endurance

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm tolerance levels and packaging options. Confirm RoHS compliance status and check for discontinuance notifications or product change notices prior to finalizing procurement decisions.

Selection Notes

Select this component when precise voltage regulation is required alongside high power handling capabilities. Ensure thermal management strategies accommodate the specified junction-to-lead thermal resistance for optimal performance under steady-state conditions.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The 'C' suffix indicates a tighter ±2% voltage tolerance compared to standard variants, while the 'TR12' designation specifies tape and reel packaging for automated assembly processes.

Replacement Considerations

Consult official manufacturer documentation for confirmed substitute part numbers. Verify that any replacement maintains equivalent power ratings, voltage tolerances, and physical package dimensions.
