1N5367E3/TR12

Overview

The Microchip Technology 1N5367E3/TR12 is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 43 V. It belongs to the JEDEC registered 1N5333B through 1N5388B series and features a 5 W power dissipation rating at 25 °C. The device utilizes a T-18 axial leaded package and operates within a temperature range of -65 °C to +150 °C. Electrical characteristics include a maximum dynamic impedance of 20 Ω, a maximum reverse leakage current of 500 nA, and a maximum steady-state regulator current of 2.8 A.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for standard through-hole integration
• Withstands high surge stresses and exhibits minimal changes in voltage versus current
• Complies with RoHS standards and requires no dry pack due to Level 1 moisture classification

Applications

• Voltage reference circuits requiring stable DC levels
• Overvoltage protection stages in power supply designs
• General-purpose voltage regulation in industrial equipment

Procurement Notes

Verify the component status as this specific part number may be discontinued or subject to limited availability. Confirm that the 'e3' suffix indicates RoHS compliance and the 'TR12' suffix denotes tape and reel packaging per EIA-296 standards. Ensure the procurement source provides valid traceability documentation for the Microsemi/Microchip manufacturing origin.

Selection Notes

Select this component when a 43 V regulation point is required with a 5 W power handling capability. The T-18 package offers low thermal resistance for heat sinking applications. Consider the ±5% tolerance associated with the B-series designation unless tighter tolerances are specified by alternative suffixes. Verify that the operating environment remains within the -65 °C to +150 °C range.

Part Context

This device is part of the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes originally manufactured by Microsemi Scottsdale Division. The series covers a wide voltage selection from 3.3 V to 200 V. The 1N5367 variant specifically targets the 43 V regulation segment within this extensive lineup of plastic encapsulated axial-leaded components.

Replacement Considerations

Public confirmed substitute part numbers include SMBJ5367AE3/TR13.
