1N5348AE3/TR13

Overview

The Microchip Technology 1N5348AE3/TR13 is a silicon 5-watt Zener diode with an 11-volt nominal breakdown voltage. It features a ±10% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes an axial-lead DO-201 package and includes a tape-and-reel suffix for automated handling.

Feature Summary

• Provides stable voltage regulation across a wide operating current and temperature range
• Features flexible axial-lead mounting terminals for versatile integration
• Withstands high surge stresses and exhibits minimal voltage change versus current

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in measurement systems

Procurement Notes

Verify the component origin, as the datasheet identifies Microsemi Scottsdale Division as the manufacturer while the model prefix indicates Microchip Technology. Confirm RoHS compliance via the e3 suffix and ensure the TR13 designation matches the required reel packaging specifications for your assembly line.

Selection Notes

Select this component when a 5-watt axial Zener diode with an 11-volt nominal rating is required. The A suffix confirms a ±10% tolerance band suitable for general-purpose applications. Ensure adequate heat sinking is provided to maintain performance within the specified thermal resistance limits.

Part Context

This part belongs to the JEDEC registered 1N5333 through 1N5388B series of silicon Zener diodes. The series offers a broad selection of voltages from 3.3V to 200V in a robust plastic encapsulated axial-lead package designed for high-power dissipation applications.

Replacement Considerations

Direct replacements include other manufacturers' 1N5348 variants or equivalent 5W Zener diodes with matching 11V ratings and axial lead configurations. Verify that any substitute meets the same thermal and electrical specifications.
