1N5377B-TP

Overview

The MCC 1N5377B-TP is a 5W Zener diode in the DO-15 axial package. It provides a nominal Zener voltage of 91V with a ±5% tolerance. The device operates within a junction temperature range of -55°C to +200°C and features a maximum thermal resistance of 83°C/W from junction to ambient. Electrical characteristics include a test current of 15mA, a maximum dynamic impedance of 75 Ohms at 69.2V reverse voltage, and a maximum reverse leakage current of 0.5µA.

Feature Summary

• Provides stable voltage regulation for circuits requiring high-voltage reference points
• Features epoxy molding compound meeting UL 94 V-0 flammability rating
• Capable of handling significant power dissipation up to 5W with appropriate heat sinking

Applications

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

Procurement Notes

Verify that the ordering suffix matches the required packaging format, such as Tape & Reel or Ammo Packing. Confirm compliance requirements including RoHS status and Halogen-free availability if specified by adding the -HF suffix. Ensure the component is sourced from authorized distributors to guarantee authenticity and traceability.

Selection Notes

Select this component when a precise 91V regulation point is required in an axial leaded package. Consider the thermal resistance limits and derating curves for continuous operation above 75°C. Verify that the surge current capabilities align with the expected transient conditions in the target application circuit.

Part Context

This part belongs to the 1N5338B through 1N5388B series manufactured by Micro Commercial Components. The series covers a wide voltage range from 5.1V to 200V, all sharing the same 5W power dissipation rating and DO-15 mechanical footprint. The -TP suffix indicates standard tape and reel packaging options.

Replacement Considerations

Direct substitutes within the same series include parts with similar voltage ratings, though exact 91V equivalents may require checking specific datasheet values for dynamic impedance and leakage current compatibility.
