1N5358AE3/TR13

Overview

The Microchip Technology 1N5358AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 22V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial lead T-18 package and RoHS-compliant e3 plating. Electrical characteristics include a maximum reverse current of 0.5 µA tested at 15.8V and a dynamic impedance of 3.5 Ohms. It operates within a temperature range of -65°C to +150°C.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers flexible axial-lead mounting terminals
• Features void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards

Applications

• Voltage regulation circuits requiring 5W power dissipation
• Power supply protection against transient overvoltages
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the component origin as the datasheet originates from Microsemi Scottsdale Division, now part of Microchip Technology. Confirm that the TR13 suffix indicates tape and reel packaging per EIA-296 standards. Ensure the specific A suffix corresponds to the required ±10% voltage tolerance for your design specifications before procurement.

Selection Notes

Select this component when a 22V regulation point is required with moderate precision. The axial T-18 package suits through-hole applications where higher thermal mass is beneficial. Consider the 5W power rating and derating curves for heat sinking requirements. Verify compatibility with existing PCB footprints designed for standard DO-41 or T-18 packages.

Part Context

This part belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series covers a wide voltage selection from 3.3V to 200V. The e3 suffix denotes RoHS compliance, while the TR suffix indicates tape and reel availability. These devices are JEDEC registered and offer various tolerance options via suffix letters.
