1N5379B-TP

Overview

The MCC 1N5379B-TP is a 5-watt Zener diode housed in the DO-15 axial through-hole package. It provides a nominal Zener voltage of 110 V 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 15°C/W from junction to lead. Electrical characteristics include a maximum dynamic impedance of 125 Ohms, a reverse current of 0.5 µA at 83.6 V, and a maximum regulator current of 43 mA.

Feature Summary

• Halogen-free epoxy construction compliant with UL 94 V-0 flammability ratings
• Lead-free finish and RoHS compliance designation
• High-temperature solder exemption applied per EU Directive Annex 7a

Applications

• Voltage regulation circuits requiring high-voltage stability
• Overvoltage protection for sensitive electronic components
• Reference voltage generation in power supply designs

Procurement Notes

Verify that the ordering suffix matches the required packaging format, as TP indicates standard tape and reel or cut tape options. Confirm halogen-free status if specified by adding the HF suffix. Ensure compatibility with authorized distributors to guarantee genuine parts and full traceability. Check datasheet notes regarding maximum operating temperatures under DC versus pulsed conditions.

Selection Notes

Select this component when a stable 110 V reference is needed in a through-hole assembly. The DO-15 package supports up to 5 W of power dissipation with appropriate heat sinking. Consider the 125 Ohm dynamic impedance for applications requiring moderate regulation precision. Verify that the surge current capabilities align with expected transient events in the target circuit design.

Part Context

This part belongs to the 1N5338B through 1N5388B series, covering Zener voltages from 5.1 V to 200 V. All devices in this family share identical physical dimensions and thermal characteristics defined in the DO-15 package specifications. The series is designed for general-purpose voltage regulation and protection tasks across industrial and commercial electronics.

Replacement Considerations

Cross-reference with other manufacturers offering 1N5379B equivalents in the DO-15 package. Verify that substitute parts maintain the same 110 V nominal voltage, 5 W power rating, and ±5% tolerance. Ensure thermal resistance and surge current specifications meet or exceed the original MCC requirements.
