1N5352AE3/TR12

Overview

The Microchip Technology 1N5352AE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 15V and a ±10% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 75µA at 10.8V and a dynamic impedance of 2.5Ω at a test current of 75mA. The device utilizes a T-18 axial lead package and is supplied in tape and reel format.

Feature Summary

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

Applications

• Voltage regulation circuits requiring 5W power dissipation
• High surge stress environments
• Applications needing wide temperature operation from -65°C to +150°C

Procurement Notes

Verify the specific suffix configuration against official datasheets to confirm RoHS compliance and packaging type. Confirm availability status as distribution channels may vary. Ensure thermal management meets the specified junction-to-lead resistance requirements for optimal performance.

Selection Notes

Select this component when a 15V reference with ±10% tolerance is required. Consider the 5W power rating and T-18 package size for adequate heat sinking. Verify that the 75µA leakage current and 2.5Ω impedance meet circuit specifications.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of axial-leaded 5.0 watt Zeners. The 'e3' suffix indicates RoHS compliance, while 'TR12' specifies the tape and reel packaging format. These devices are designed for plastic encapsulation with Level 1 moisture classification.

Replacement Considerations

Consult the manufacturer's discontinuance notifications or equivalent product lists for verified substitutes. Cross-reference electrical parameters such as voltage tolerance and power dissipation before substitution.
