1N5357AE3/TR13

Overview

The Microchip Technology 1N5357AE3/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 20 V with a ±10% tolerance, indicated by the 'A' suffix. The device features an axial T-18 package and operates within a temperature range of -65°C to +150°C. Electrical characteristics include a maximum dynamic impedance of 3.0 Ohms and a maximum reverse current of 0.5 µA tested at 14.4 V. The component is RoHS compliant (e3 suffix) and supplied in tape and reel packaging (TR suffix).

Feature Summary

• Provides stable voltage regulation across 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.
• Compliant with RoHS standards and moisture classification Level 1.

Applications

• Voltage regulation circuits requiring 5-watt power dissipation.
• Power supply protection against transient overvoltages.
• Reference voltage generation in electronic systems.

Procurement Notes

Verify the part number includes the e3 suffix for RoHS compliance and TR suffix for tape and reel packaging. Confirm the A suffix indicates the required ±10% voltage tolerance. Check manufacturer documentation for specific screening levels or military equivalents if applicable. Ensure thermal management meets the specified derating curves for the intended application environment.

Selection Notes

Select this component when a 20 V Zener voltage with ±10% tolerance is required in a 5-watt axial package. Consider the thermal resistance of 25 °C/W junction-to-lead for heat sinking requirements. Evaluate the maximum steady-state power dissipation limits based on the mounting method and ambient temperature conditions specified in the datasheet.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3 V to 200 V. The 1N5357 variant specifically targets the 20 V regulation point within this extensive lineup of plastic encapsulated, axial-leaded devices.
