1N5373CE3/TR12

Overview

The Microchip Technology 1N5373CE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 68 V. It features a tight ±2% tolerance and operates within a temperature range of -65°C to +150°C. The device utilizes an axial T-18-2 package and includes a tape-and-reel suffix for automated handling.

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 through-hole integration

Applications

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

Procurement Notes

Verify the component's end-of-life status and discontinuance notifications prior to procurement. Confirm that the specific ordering suffix matches the required RoHS compliance and packaging format, as these attributes define the physical and environmental specifications of the delivered unit.

Selection Notes

Select this component when a precise 68 V reference with tight tolerance is required in a high-power application. Ensure adequate heat sinking is provided to maintain operation within the specified thermal limits and maximize the steady-state power dissipation capability.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of 5-watt Zener diodes. The 'e3' suffix indicates lead-free construction, while the 'TR12' suffix designates the tape-and-reel packaging configuration for automated assembly processes.

Replacement Considerations

Consult official manufacturer documentation for verified substitute part numbers. Cross-reference electrical parameters such as voltage tolerance and dynamic impedance before implementing any alternative components.
