1N5359C/TR8

Overview

The Microchip Technology 1N5359C/TR8 is a silicon 5.0-watt Zener diode in the JEDEC registered 1N5333-5388B series, featuring a nominal voltage of 24 V with ±2% tolerance. It operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package. The device exhibits a maximum dynamic impedance of 3.5 ohms at a test current of 50 mA, with a maximum reverse leakage current of 0.5 µA. It withstands high surge stresses and provides stable voltage regulation over broad operating currents.

Feature Summary

• Provides tight voltage regulation with ±2% tolerance for precision applications
• Withstands high surge stresses and non-sensitive to ESD per MIL-STD-750 Method 1020
• Features flexible axial-lead mounting terminals for secure installation
• Maintains minimal changes in voltage versus current as specified by voltage regulation

Applications

• Voltage regulation over broad operating current and temperature ranges
• High specified maximum current applications with adequate heat sinking
• General purpose voltage reference circuits requiring tight tolerances

Procurement Notes

Verify component authenticity through authorized channels due to potential supply chain variations. Confirm specific suffix requirements such as TR8 for tape and reel packaging against original design specifications. Ensure compliance with moisture classification Level 1 standards during storage and handling procedures.

Selection Notes

Select this component when precise voltage regulation is required alongside high power dissipation capabilities. The C suffix indicates a tighter tolerance compared to standard B or A variants. Consider thermal resistance characteristics and derating curves for optimal performance under varying ambient temperatures.

Part Context

This part belongs to the Microsemi Scottsdale Division 1N5333B through 1N5388B series of silicon 5-watt Zener diodes.
