1N5352/TR8

Overview

The Microchip Technology 1N5352/TR8 is a silicon Zener diode with a nominal voltage of 15V and a ±10% tolerance. It operates within a power dissipation range up to 5W at 25°C, featuring a maximum reverse current of 75µA and a dynamic impedance of 2.5Ω. The device supports a maximum regulator current of 6.3A and withstands surge currents up to 450A. Packaged in the T-18 axial lead format with tape and reel configuration, it functions reliably across an operating temperature range from -65°C to +150°C.

Feature Summary

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

Applications

• Voltage regulation circuits requiring robust thermal performance
• Power supply protection against high surge stresses
• Industrial equipment operating under extreme temperature conditions

Procurement Notes

Verify the specific suffix 'TR8' confirms the tape and reel packaging format as documented in the datasheet. Ensure the component matches the JEDEC registered 1N5352B series specifications. Confirm RoHS compliance status if required by your assembly process. Cross-reference the manufacturer's latest documentation for any discontinuance notifications or manufacturing changes.

Selection Notes

Select this component when a 15V Zener reference is needed with high current handling capabilities. The 5W power rating allows operation at high DC currents provided adequate heat sinking is utilized. Consider the T-18 package dimensions for PCB layout constraints. Verify that the ±10% voltage tolerance aligns with your circuit design requirements.

Part Context

This part belongs to the 1N5333 through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V. These devices are designed for applications requiring high power dissipation and reliable voltage regulation in harsh environments.

Replacement Considerations

Equivalent parts include other 5W Zener diodes with 15V nominal voltage and similar tolerance ratings. Verify pinout compatibility and thermal resistance characteristics before substitution. Check for matching surge current ratings and operating temperature ranges.
