1N5352CE3/TR13

Overview

The Microchip Technology 1N5352CE3/TR13 is a silicon 5.0-watt Zener diode from the JEDEC registered 1N5333-5388B series, manufactured by the Microsemi Scottsdale Division. It provides voltage regulation at a nominal Zener voltage of 15 volts with a tight tolerance of plus or minus 2 percent, indicated by the C suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18 axial-lead package. Electrical characteristics include a maximum dynamic impedance of 2.5 ohms and a maximum reverse current of 1.0 microampere.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Features flexible axial-lead mounting terminals for versatile installation
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

• Voltage regulation in power supply circuits
• Overvoltage protection systems
• Reference voltage generation in electronic instrumentation

Procurement Notes

Verify that the part number includes the e3 suffix to confirm RoHS compliance and the TR suffix to ensure tape and reel packaging. Confirm the C suffix indicates the required plus or minus 2 percent voltage tolerance. Ensure the component originates from authorized distribution channels to guarantee authenticity and traceability of the Microsemi Scottsdale Division manufacturing origin.

Selection Notes

Select this component when a 15-volt regulation point with high precision is required. The plus or minus 2 percent tolerance makes it suitable for applications demanding tighter voltage accuracy than standard B or A suffix devices. Consider the 5-watt power dissipation capability and thermal resistance specifications to ensure adequate heat sinking for steady-state operation.

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 ranging from 3.3 to 200 volts. The specific model utilizes a void-free transfer molded thermosetting epoxy body meeting UL94V-0 standards. It is designed for operation at high maximum DC currents when adequately heat sunk.

Replacement Considerations

Equivalent parts within the same series include 1N5352B (plus or minus 5% tolerance) and 1N5352D (plus or minus 1% tolerance). Surface mount equivalents are available as SMBJ5352B or SMBG5352B.
