1N5358BE3/TR8

Overview

The Microchip Technology 1N5358BE3/TR8 is a silicon Zener diode with a nominal voltage of 22 V and a power dissipation rating of 5 W. It features a ±5% voltage tolerance, a maximum reverse leakage current of 0.5 µA, and a dynamic impedance of 3.5 Ω. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile installation
• Withstands high surge stresses without damage
• RoHS compliant construction available via the e3 suffix

Applications

• Voltage regulation in electronic circuits
• Surge protection applications
• Reference voltage generation

Procurement Notes

Verify that the component matches the specific JEDEC registered series requirements. Confirm the presence of the e3 suffix for RoHS compliance and TR8 for tape and reel packaging. Ensure the manufacturer designation aligns with Microchip Technology or its predecessor entities as documented in official datasheets.

Selection Notes

Select this component when a 5 W power rating and 22 V regulation are required. The B suffix indicates a standard 5% tolerance suitable for general-purpose applications. Consider thermal derating curves if ambient temperatures exceed standard limits or if heat sinking is not utilized.

Part Context

This part belongs to the 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 e3 suffix denotes RoHS compliance, while the TR8 suffix indicates tape and reel packaging for automated assembly.

Replacement Considerations

Cross-reference with other manufacturers' 5 W Zener diodes rated at 22 V. Verify that any substitute meets the same T-18 package dimensions and thermal resistance specifications to ensure compatibility with existing board layouts.
