1N5367C/TR8

Overview

The Microchip Technology 1N5367C/TR8 is a silicon 5-watt Zener diode from the JEDEC registered 1N5333-5388B series. It provides voltage regulation at a nominal Zener voltage of 43 volts with a tight tolerance of plus or minus 2 percent, indicated by the C suffix. The device operates within an ambient temperature range of -65°C to +150°C and features a T-18 axial lead package. Electrical characteristics include a maximum dynamic impedance of 20 ohms and a maximum reverse current of 0.5 microamperes.

Feature Summary

• Provides stable voltage regulation across a broad operating current and temperature range
• Features flexible axial-lead mounting terminals for through-hole applications
• Withstands high surge stresses and exhibits minimal voltage change versus current
• Moisture classification is Level 1 per IPC/JEDEC J-STD-020B requiring no dry pack

Applications

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

Procurement Notes

Verify the component status as this part may be discontinued or subject to limited availability. Confirm that the TR8 suffix indicates tape and reel packaging compliant with EIA-296 standards. Ensure the manufacturer designation aligns with current Microchip Technology sourcing channels rather than legacy Microsemi documentation. Validate RoHS compliance status if required for specific manufacturing processes.

Selection Notes

Select this component when precise voltage regulation is required with a tolerance tighter than standard B or A suffix devices. The 5-watt power dissipation rating supports high-current applications provided adequate heat sinking is implemented. Consider the thermal resistance specifications for junction-to-lead and junction-to-ambient conditions during circuit design to ensure operation remains within safe limits.

Part Context

This device belongs to the 1N5333B through 1N5388B series of silicon 5-watt Zener diodes manufactured by Microchip Technology's Scottsdale Division. The series offers a wide selection of voltages ranging from 3.3 to 200 volts. The C suffix specifically denotes a plus or minus 2 percent voltage tolerance, distinguishing it from standard 5 percent or 10 percent variants.

Replacement Considerations

Equivalent parts within the same series include 1N5367B for 5 percent tolerance or 1N5367D for 1 percent tolerance. Surface mount equivalents are available as SMBJ5367B or SMBG5367B. Verify pinout compatibility and thermal performance when substituting with other manufacturers' 5-watt axial Zener diodes.
