1N5354AE3/TR13

Overview

The Microchip Technology 1N5354AE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 17 V with a ±10% tolerance. 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 2.5 Ohms at a test current of 70 mA, a maximum reverse leakage current of 0.5 µA at 12.2 V, and a maximum regulator current of 5.8 A. The component is RoHS compliant and available in tape and reel packaging.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and offers minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile integration
• Moisture classification Level 1 requiring no dry pack storage

Applications

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

Procurement Notes

Verify the manufacturer origin as the part originates from the Microsemi Scottsdale Division, now part of Microchip Technology. Confirm the specific suffixes match the required tolerance (A for ±10%) and packaging (TR for Tape & Reel). Ensure compliance with RoHS standards and check for any military screening prefixes if applicable. Validate that the axial lead length meets thermal resistance requirements for your specific heat sinking configuration.

Selection Notes

Select this component when a 17 V regulated output is needed with a 5-watt power rating. The ±10% tolerance suits applications where tighter precision is not critical. Consider the T-18 axial package for through-hole mounting. Evaluate thermal management needs, as steady-state power dissipation depends on ambient temperature and lead length. Compare dynamic impedance and leakage current specifications against circuit sensitivity requirements.

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 3.3 V to 200 V. The 'e3' suffix indicates RoHS compliance with annealed matte-tin plating. The 'TR' suffix denotes tape and reel packaging per EIA-296 standards. These devices are plastic encapsulated with void-free transfer molded thermosetting epoxy bodies meeting UL94V-0 flammability ratings.
