1N5352CE3/TR8

Overview

The Microchip Technology 1N5352CE3/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 at 25°C, operating within a temperature range of -65°C to +150°C. The device utilizes an axial-lead T-18 package and includes RoHS compliance indicated by the e3 suffix.

Feature Summary

• Provides precise voltage regulation with tight manufacturing tolerances
• Capable of handling high surge stresses and steady-state currents
• Features flexible axial-lead mounting terminals for through-hole applications

Applications

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

Procurement Notes

Verify the specific C suffix indicates the required ±2% tolerance level. Confirm the TR8 tape and reel packaging format matches assembly requirements. Ensure the e3 designation aligns with environmental compliance standards for the target application.

Selection Notes

Select this component when strict voltage accuracy is necessary compared to standard tolerance variants. Consider the thermal resistance characteristics and derating curves if operating near maximum power limits. Verify lead length requirements against board layout constraints.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options defined by suffix letters.

Replacement Considerations

Equivalent parts include other 1N5352 variants with different tolerances (e.g., 1N5352A or 1N5352B) if wider voltage deviation is acceptable. Surface mount equivalents such as SMBJ5352C may be used with appropriate mechanical adaptation.
