1N3014B

Overview

The Microchip Technology 1N3014B is a silicon Zener diode rated for 180V nominal voltage with ±5% tolerance. It features a maximum power dissipation of 10W and operates within a temperature range of -65°C to +175°C. The device exhibits a maximum reverse leakage current of 10µA and a Zener impedance of 260 Ohms. Packaged in the DO-213AA (TO-5) metal can, it is designed for stud-mount applications requiring high-voltage regulation.

Feature Summary

• High-power voltage regulation capability up to 10W
• Wide operating temperature range suitable for harsh environments
• Metal can construction for robust mechanical stability

Applications

• High-voltage power supply regulation
• Industrial control systems
• Military and aerospace electronic circuits

Procurement Notes

Verify the manufacturer designation as Microchip Technology or its predecessor Microsemi Corporation when sourcing. Confirm the package type matches DO-213AA specifications. Ensure the voltage tolerance aligns with the required ±5% standard. Check for any specific military qualification markings if applicable to the end-use environment.

Selection Notes

Select this component for applications requiring stable 180V reference points under high thermal stress. The 10W power rating allows for significant current handling compared to smaller packages. Consider the TO-5 form factor for compatibility with existing stud-mount hardware and heat sinking solutions in industrial enclosures.

Part Context

This part belongs to the legacy series of high-power silicon Zener diodes originally developed by Microsemi Corporation. These components are widely recognized for their reliability in critical infrastructure. The 1N3014B specifically addresses the need for durable voltage regulation in sectors where standard surface-mount devices cannot withstand environmental extremes.

Replacement Considerations

Direct substitutes include other 180V 10W Zener diodes in DO-213AA packages from manufacturers such as Central Semiconductor. Verify pinout compatibility and thermal resistance characteristics before substitution. Cross-reference with JANTX1N55 series variants for potential military-grade equivalents.
