1N5349AE3/TR13

Overview

The Microchip Technology 1N5349AE3/TR13 is a silicon 5-watt Zener diode in the JEDEC registered 1N5333-5388B series. It features an axial lead T-18 package and provides voltage regulation with a nominal Zener voltage of 12V and a ±10% tolerance. The device operates within a temperature range of -65°C to +150°C, includes RoHS compliance via the e3 suffix, and utilizes tape-and-reel packaging indicated by the TR13 suffix.

Feature Summary

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

Applications

• Voltage regulation circuits
• Surge protection applications
• General purpose electronic equipment

Procurement Notes

Verify the component manufacturer origin, as the datasheet identifies Microsemi while the model implies Microchip Technology. Confirm that the specific ordering suffixes correspond to the required RoHS compliance (e3) and tape-and-reel packaging (TR). Ensure the part number matches the exact voltage and tolerance specifications required for the design.

Selection Notes

Select this component when a 5-watt power dissipation rating and axial lead configuration are necessary. The 12V nominal voltage with ±10% tolerance suits standard regulation needs. Consider thermal derating requirements if ambient temperatures exceed 25°C or if mounted on FR4 PCBs rather than using adequate heat sinking.

Part Context

This component belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V. The 'A' suffix indicates a standard ±10% voltage tolerance, while the 'e3' suffix denotes RoHS compliant annealed matte-tin plating.
