1N5367CE3/TR12

Overview

The Microchip Technology 1N5367CE3/TR12 is a silicon unidirectional voltage regulator diode with a nominal Zener voltage of 43 V. It belongs to the JEDEC registered 1N5333-5388B series, offering a power dissipation rating of 5.0 watts at 25°C. The device features a tight voltage tolerance of ±2%, indicated by the 'C' suffix, and operates within a temperature range of -65°C to +150°C. Packaged in a T-18 (DO-201AE) axial lead format, this specific variant includes the 'TR12' suffix denoting tape and reel packaging.

Feature Summary

• Provides precise voltage regulation with a tight ±2% tolerance for stable reference applications
• Capable of handling high maximum DC currents when paired with adequate heat sinking
• Features flexible axial-lead mounting terminals suitable for through-hole integration
• Withstands high surge stresses and exhibits minimal voltage change versus current

Applications

• Voltage regulation over broad operating current and temperature ranges
• High surge stress protection circuits
• Precision voltage reference designs requiring tight tolerances

Procurement Notes

Verify the exact part number against official manufacturer documentation before procurement. Confirm that the 'TR12' suffix correctly specifies the tape and reel packaging configuration required for your assembly process. Ensure compatibility with RoHS compliance standards if applicable to your manufacturing requirements.

Selection Notes

Select this component when a 43 V Zener voltage with ±2% tolerance is required. Consider the 5-watt power dissipation capability and thermal resistance characteristics for proper heat sinking design. Verify that the axial lead package fits the mechanical constraints of the target PCB layout.

Part Context

This device is part of the broader 1N5333B through 1N5388B series of 5-watt silicon Zener diodes manufactured by Microsemi (now Microchip Technology). The series covers a wide voltage selection from 3.3V to 200V, utilizing different suffix letters to denote specific voltage tolerances such as A, B, C, or D.

Replacement Considerations

Consult official datasheets for direct equivalents within the 1N5333-5388B series. Verify that any substitute maintains the 43 V nominal voltage, ±2% tolerance, and 5W power rating.
