1N5379B-AP

Overview

The 1N5379B-AP is a Zener diode manufactured by Micro Commercial Components (MCC). It features a nominal Zener voltage of 110 V with a tolerance of ±5%. The device is designed for through-hole mounting in a DO-204AC (DO-15) axial package. It supports a maximum power dissipation of 5 W and operates within a junction temperature range of -55°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 500 nA at 83.6 V, a Zener impedance of 125 Ohms, and a forward voltage of 1.2 V at 1 A.

Feature Summary

• Provides stable voltage regulation at a nominal 110 V reference level.
• Capable of handling high power dissipation up to 5 W for robust circuit protection.
• Constructed with silicon technology for reliable unidirectional operation.

Applications

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

Procurement Notes

Verify the specific suffix AP against official MCC documentation to confirm packaging details and compliance status. Ensure the DO-15 package dimensions match your PCB layout requirements. Cross-reference the 110 V rating and 5 W power dissipation limits with your circuit design specifications before procurement.

Selection Notes

Select this component when a 110 V Zener reference is required with high power handling capabilities. The DO-15 through-hole package is suitable for applications requiring mechanical stability. Consider the 125 Ohm impedance and 500 nA leakage current if low-noise or high-impedance performance is critical for the application.

Part Context

This part belongs to the 1N53xx series of high-power Zener diodes from Micro Commercial Components. These devices are standardized axial leaded diodes commonly used in industrial and commercial electronics. The 1N5379B variant specifically targets the 110 V breakdown voltage segment within this high-power family.

Replacement Considerations

Compatible substitutes include the Diotec Semiconductor 1N5379B and the Diodes Incorporated 1N5379B-T. Verify that alternative manufacturers offer identical 110 V Zener voltage, 5 W power rating, and DO-15 package compatibility to ensure direct interchangeability.
