1N5359C/TR12

Overview

The Microchip Technology 1N5359C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 24 V. It features a tight ±2% tolerance and operates within a temperature range of -65°C to +150°C. The device has a maximum dynamic impedance of 3.5 ohms, a maximum reverse current of 0.5 µA, and a maximum regulator current of 4.4 A. Packaged in an axial T-18 case with a TR suffix for tape and reel delivery.

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

Applications

• Voltage regulation circuits requiring high power dissipation
• High current applications with adequate heat sinking
• Surge protection environments

Procurement Notes

Verify the component against official datasheets to confirm the specific C suffix indicates a ±2% tolerance. Ensure the TR12 designation matches the required tape and reel packaging specifications. Confirm that the manufacturer and part number align with the intended design requirements before procurement.

Selection Notes

Select this component when a precise 24 V reference is needed with strict tolerance limits. Consider the 5 W power rating and thermal resistance characteristics for proper heat sinking. Verify compatibility with the T-18 axial lead package and tape and reel handling requirements.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3 V to 200 V. The C suffix specifically denotes a tighter ±2% voltage tolerance compared to standard B or A suffix variants.

Replacement Considerations

Compatible substitutes include other 1N5359 variants such as 1N5359B or 1N5359A, provided the tolerance requirements are adjusted accordingly.
