1N5358AE3/TR8

Overview

The Microchip Technology 1N5358AE3/TR8 is a silicon axial-leaded Zener diode with a nominal voltage of 22V and a tolerance of ±10%. It belongs to the JEDEC registered 1N5333-5388B series, offering a power dissipation of 5.0 watts at 25°C. The device features a T-18 plastic package with flexible mounting terminals and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 3.5 ohms and a maximum reverse current of 0.5 µA.

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 sensitivity to electrostatic discharge

Applications

• Voltage regulation in electronic circuits
• Power supply protection against transient overvoltages
• Reference voltage generation in measurement systems

Procurement Notes

Verify that the component matches the specific suffix requirements for your application. Confirm RoHS compliance status and lead plating type (tin-lead or matte-tin) based on project specifications. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits during operation.

Selection Notes

Select this component when a 22V Zener reference with ±10% tolerance is required. Consider the 5-watt power rating and low thermal resistance design for applications demanding high DC currents. Verify that the T-18 through-hole package fits the available board space and mounting constraints.

Part Context

This part is part of the 1N5333B through 1N5388B series manufactured by Microsemi, now part of Microchip Technology. The series covers a wide voltage selection from 3.3V to 200V. The 'e3' suffix indicates RoHS compliance, while 'TR8' denotes tape and reel packaging options for automated assembly processes.

Replacement Considerations

Equivalent parts within the same series include 1N5358B and 1N5358BE3. Cross-manufacturer replacements must match the 22V nominal voltage, 5W power rating, and T-18 package dimensions.
