1N5367B-TP

Overview

The MCC 1N5367B-TP is a unidirectional silicon voltage regulator diode with a nominal Zener voltage of 43 V and a maximum power dissipation of 5 W. It features a ±5% tolerance on the nominal voltage, a maximum dynamic impedance of 20 Ω at a test current of 30 mA, and a maximum reverse leakage current of 0.5 µA at 32.7 V. The device operates within a junction temperature range of -55°C to +150°C for DC conditions, utilizing a DO-15 axial through-hole package.

Feature Summary

• Epoxy encapsulation meets UL 94 V-0 flammability rating
• Lead-free finish compliant with RoHS standards
• Halogen-free construction available upon request

Applications

• Voltage regulation in electronic circuits
• Overvoltage protection for sensitive components
• Reference voltage generation in power supplies

Procurement Notes

Verify that the ordering suffix matches the required compliance specifications. The standard suffix designates lead-free and RoHS compliance. Confirm if halogen-free requirements are met by checking for the specific additional suffix indicated in the manufacturer's ordering information section. Ensure the package type aligns with the intended PCB layout.

Selection Notes

Select this component when a 43 V reference or clamp is required in a high-power application. The 5 W power rating supports significant current handling compared to lower-wattage alternatives. Verify that the thermal resistance characteristics fit the system's heat dissipation capabilities. Consider the axial lead configuration for through-hole mounting constraints.

Part Context

This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers a wide voltage range from 5.1 V to 200 V, all sharing the same 5 W power dissipation capability and DO-15 package form factor. This specific model represents the mid-range voltage option within the lineup.

Replacement Considerations

Cross-reference with other manufacturers' 1N5367B equivalents. Verify that substitute parts maintain the 43 V nominal voltage, 5 W power rating, and DO-15 package dimensions to ensure mechanical and electrical compatibility without circuit redesign.
