Overview
The Microchip Technology 1N2986B is a 10-watt silicon Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 24V with a tolerance of ±5%. The device operates within a temperature range of -65°C to +175°C and utilizes a stud-mount configuration in the DO-203AA (DO-4) package. Key electrical characteristics include a maximum Zener impedance of 5 Ohms, a reverse leakage current of 10 µA at 18.2V, and a forward voltage of 1.5V at 2A.
Feature Summary
- High power dissipation capability of 10 watts for robust voltage regulation
- Wide operating temperature range suitable for demanding environments
- Stud-mount construction for efficient thermal management
Applications
- Industrial power supply voltage regulation
- Military and aerospace electronic systems
- High-reliability circuit protection
Procurement Notes
Verify that the specific order suffix matches the required qualification level, such as JAN, JANTX, or JANTXV, as these denote distinct reliability standards. Confirm the package type corresponds to the mechanical mounting requirements of the target assembly. Ensure compliance with relevant environmental directives if applicable to the deployment region.
Selection Notes
Select this component when a 10-watt Zener diode with a 24V nominal breakdown voltage is required. The stud-mount package facilitates direct heat sinking for high-power dissipation scenarios. Consider the ±5% tolerance and low impedance characteristics for precise regulation needs in industrial or military-grade equipment designs.
Part Context
This part belongs to the JEDEC registered 1N2970B through 1N3015B series of 10W Zener diodes. These devices offer voltage regulation values ranging from 3.9 to 200 volts. The series is qualified per MIL-PRF-19500/124, ensuring suitability for high-reliability applications requiring strict performance consistency.
Replacement Considerations
Compatible substitutes include other 10W Zener diodes with identical 24V ratings and stud-mount packages. Verify that alternative parts meet the same MIL-PRF-19500/124 qualification levels if military-grade reliability is mandated. Ensure thermal resistance and pinout compatibility match the existing design constraints.
