1N5367C/TR12

Overview

The Microchip Technology 1N5367C/TR12 is a silicon 5-watt Zener diode with a nominal voltage of 43 V and a ±2% tolerance. It operates within a temperature range of -65°C to +150°C, featuring a maximum reverse current of 0.5 µA at 31 V and a dynamic impedance of 20 Ω at a test current of 30 mA. The device utilizes an axial T-18 package and supports tape-and-reel packaging.

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 JEDEC registration status and confirm RoHS compliance details directly with the manufacturer or authorized distributors. Ensure that the specific suffix designations match the required tolerance and packaging specifications for your application requirements.

Selection Notes

Select this component when a precise 43 V reference with tight ±2% tolerance is required. Consider the 5 W power dissipation capability and thermal resistance characteristics to ensure adequate heat sinking for steady-state operation under expected load conditions.

Part Context

This part belongs to the 1N5333B through 1N5388B series of registered 5-watt Zener diodes manufactured by Microsemi (now Microchip). The series offers a wide selection of voltages from 3.3 V to 200 V, utilizing plastic encapsulated axial leads suitable for robust industrial applications.

Replacement Considerations

Direct substitutes include other 1N5367 variants with matching tolerances, such as the standard 1N5367B (±5%) or 1N5367D (±1%), provided the tolerance difference is acceptable for the circuit design.
