Overview
The Microchip Technology 1N3014A is a silicon unidirectional Zener diode rated for 180V nominal breakdown voltage with a ±5% tolerance. It features a 10W power dissipation capability and operates within a temperature range of -65°C to +175°C. The component utilizes a DO-213AA (DO-4) stud-mount package, designed for high-reliability applications requiring hermetic sealing.
Feature Summary
- Hermetically sealed glass construction for environmental protection
- Stud-mount configuration for efficient thermal management
- High-temperature operation up to 175°C junction temperature
Applications
- Voltage regulation in military aerospace systems
- Overvoltage protection circuits in harsh environments
- Reference voltage sources in high-reliability industrial equipment
Procurement Notes
Verify the specific manufacturer lot code and date code upon receipt to ensure compliance with project requirements. Confirm that the device meets the necessary quality standards, such as MIL-PRF-19500, if specified for your application. Check for any special handling instructions related to the stud-mount terminal during installation.
Selection Notes
Select this component when a robust, hermetically sealed Zener diode is required for high-power voltage regulation. The stud-mount design facilitates direct mounting to heat sinks or chassis for effective thermal dissipation. Ensure the circuit design accounts for the 10W power rating and the specific 180V breakdown voltage under expected operating conditions.
Part Context
This part belongs to the family of 10-watt Zener diodes manufactured by Microchip Technology (formerly Microsemi). These components are engineered for durability in demanding environments, offering stable voltage regulation characteristics compared to lower-power surface-mount alternatives.
Replacement Considerations
Compatible substitutes include the JANTX1N3014A variant from Microsemi/Microchip, which shares identical electrical specifications and package dimensions. Verify pinout compatibility and thermal resistance values before integrating alternative sources.
