1N5369CE3/TR12

Overview

The Microchip Technology 1N5369CE3/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 51V and a tight tolerance of ±2%. It features a maximum reverse leakage current of 500 nA, a dynamic impedance of 27 Ohms, and a maximum regulator current of 2.5 A. The device operates within a temperature range of -65°C to +150°C and utilizes a T-18 axial lead package.

Feature Summary

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

Applications

• Voltage regulation circuits requiring high power dissipation
• Power supply protection against overvoltage conditions
• Reference voltage generation in industrial equipment

Procurement Notes

Verify the component status as discontinued or end-of-life before finalizing designs. Confirm RoHS compliance details and specific manufacturing lot dates. Ensure that the tape and reel packaging specifications match the automated assembly requirements. Validate thermal derating curves against the intended heat sinking configuration to maintain safe operating temperatures.

Selection Notes

Select this component when a 51V reference with ±2% precision is required at 5W power levels. Consider the T-18 package dimensions for board layout constraints. Evaluate the thermal resistance characteristics relative to the ambient environment. Compare the dynamic impedance and leakage current specifications against circuit sensitivity requirements.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series covers a voltage range from 3.3V to 200V. The 'C' suffix indicates a ±2% voltage tolerance, while the 'e3' suffix denotes RoHS compliance. The 'TR12' suffix specifies the tape and reel packaging format.

Replacement Considerations

Consult official datasheets for direct equivalents within the 1N5333B-1N5388B series. Verify pinout compatibility and thermal performance for any cross-manufacturer substitutions.
