1N5358C/TR8

Overview

The Microchip Technology 1N5358C/TR8 is a silicon Zener diode with a nominal voltage of 22V and a tight tolerance of ±2%. It features a maximum power dissipation of 5W, a dynamic impedance of 3.5 ohms, and a maximum reverse leakage current of 0.5 µA. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Feature Summary

• Provides precise voltage regulation over 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

Applications

• Voltage regulation circuits requiring tight tolerance specifications
• Power supply protection against high surge stresses
• Electronic systems operating across wide temperature ranges

Procurement Notes

Verify the specific suffix 'TR8' against official documentation to confirm tape and reel packaging details. Confirm RoHS compliance status as indicated by the manufacturer's current datasheet revisions. Ensure the component meets all environmental and screening requirements specified for your application before procurement.

Selection Notes

Select this component when a 22V Zener voltage with ±2% tolerance is required. Consider the 5W power rating and thermal resistance characteristics for adequate heat sinking. Verify that the T-18 package dimensions align with the target PCB layout constraints.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5.0-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. Different suffix letters identify specific voltage tolerances, with the C suffix denoting ±2% precision.

Replacement Considerations
