1N5352C/TR8

Overview

The Microchip Technology 1N5352C/TR8 is a silicon Zener diode with a nominal voltage of 15V and a tolerance of ±2%. It features a maximum power dissipation of 5W, a test current of 75mA, and a maximum reverse leakage current of 10µA. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Feature Summary

• Provides precise voltage regulation with tight manufacturing tolerances
• Capable of handling high surge stresses and steady-state currents
• Features low thermal resistance for efficient heat dissipation

Applications

• Voltage reference circuits
• Overvoltage protection systems
• Power supply regulation

Procurement Notes

Verify the component origin as this part number originates from the Microsemi Scottsdale Division, which has been acquired by Microchip Technology. Confirm that the specific suffixes match the required JEDEC registration and tape-and-reel packaging specifications before finalizing procurement orders.

Selection Notes

Select this component when a stable 15V reference with strict ±2% accuracy is required in a high-power environment. Ensure adequate heat sinking is provided to maintain performance within the specified junction-to-lead thermal resistance limits during continuous operation.

Part Context

This device belongs to the 1N5333B through 1N5388B series of registered 5-watt Zener diodes. The 'C' suffix specifically denotes the tighter ±2% voltage tolerance compared to standard B or A suffix variants. The 'TR8' indicates the reel-based packaging format.

Replacement Considerations

Direct replacements include other 1N5352 variants with matching tolerance suffixes (e.g., 1N5352B) or equivalent 5W Zener diodes from other manufacturers that meet the same electrical and mechanical specifications.
