1N5367B/TR12

Overview

The Microchip Technology 1N5367B/TR12 is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 43 V and a maximum power dissipation of 5.0 W at 25°C. It features a ±5% voltage tolerance, a maximum dynamic impedance of 20 Ω, and a maximum reverse leakage current of 0.5 μA. 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 5W power handling
• High surge stress environments
• General purpose voltage reference applications

Procurement Notes

Verify the component's authenticity against official Microchip specifications. Confirm that the TR12 suffix corresponds to the tape and reel packaging option as defined in the datasheet. Ensure the part meets the required environmental standards and thermal characteristics for your specific application before procurement.

Selection Notes

Select this component when a 43 V Zener voltage with tight ±5% tolerance is required. Consider the 5W power rating and T-18 package size for adequate heat sinking. Verify compatibility with existing circuit layouts due to the axial lead configuration and ensure the operating temperature range suits the environment.

Part Context

This part belongs to the JEDEC registered 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microsemi (now Microchip Technology). The series offers a wide selection of voltages from 3.3V to 200V with various tolerance options identified by suffix letters.

Replacement Considerations

Consult the manufacturer's documentation for direct equivalents or cross-reference lists. Verify that any substitute maintains the same 5W power rating, 43V Zener voltage, ±5% tolerance, and T-18 package dimensions to ensure mechanical and electrical compatibility.
