Overview
The Microchip Technology 1N3008B is a silicon 10-watt Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 120V 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-213AA (DO-4) package. Key electrical characteristics include a maximum Zener impedance of 75 Ohms, a reverse leakage current of 10 µA at 83.6 V, and a forward voltage of 1.5 V at 2 A.
Feature Summary
- Provides stable voltage regulation with a 10W power dissipation rating
- Engineered for high-temperature operation up to 175°C
- Utilizes robust stud-mount construction for secure chassis installation
Applications
- High-power voltage reference circuits
- Overvoltage protection systems
- Industrial power supply regulation
Procurement Notes
Verify the specific manufacturer source, as the 1N3008B designation has been produced by multiple entities including Microchip, Microsemi, and Solid State Inc. Ensure the datasheet matches the required MIL-PRF-19500/124 qualification levels if military-grade performance is necessary. Confirm package compatibility and mounting hardware requirements prior to integration.
Selection Notes
Select this component when a 120V regulation point is required with significant power handling capabilities. The stud-mount form factor is suitable for direct thermal coupling to heat sinks or chassis structures. Consider the ±5% tolerance and 75 Ohm impedance limits against circuit sensitivity requirements.
Part Context
This part belongs to the JEDEC registered 1N2970B through 1N3015B series of 10W Zener diodes. These components are available in commercial versions and qualified levels such as JAN, JANTX, and JANTXV. The series covers voltage regulation values between 3.9V and 200V, offering standardized options for various industrial and aerospace applications.
Replacement Considerations
Direct substitutes within the same series include 1N3007B (110V) and 1N3009B (130V), provided the voltage difference is acceptable. Verify that alternative manufacturers maintain identical pinout configurations and thermal resistance specifications for equivalent performance.
