Overview
The 1N3004RB is a single Zener diode manufactured by Microchip Technology, designed for voltage regulation applications. It features a nominal Zener voltage of 91V with a tolerance of ±5% and a power dissipation rating of 10W. The device operates within a temperature range of -65°C to 175°C. Key electrical specifications include a maximum forward voltage of 1.5V at 2A and a reverse leakage current of 10µA at 69.2V. It utilizes a DO-213AA (DO-4) stud-mount package.
Feature Summary
- High power dissipation capability of 10W for robust voltage regulation
- Extended operating temperature range from -65°C to 175°C
- Stud-mount construction for efficient thermal management
Applications
- Voltage regulation in high-power electronic circuits
- Overvoltage protection systems requiring stud-mount components
- Industrial equipment operating under extreme temperature conditions
Procurement Notes
Verify the specific datasheet version and RoHS compliance status directly with Microchip Technology or authorized distributors before procurement. Confirm that the DO-213AA package dimensions match your mechanical design requirements. Ensure thermal interface materials are compatible with the stud-mount configuration for optimal heat dissipation performance.
Selection Notes
Select this component when a 91V Zener reference with 10W power handling is required. The stud-mount package necessitates direct mounting to a heatsink or chassis. Consider the ±5% voltage tolerance and the wide temperature range suitability for your specific environmental constraints compared to lower-power surface mount alternatives.
Part Context
This part belongs to the standard Zener diode family produced by Microchip Technology. It serves as a discrete voltage reference and protection element. The DO-213AA package is a legacy through-hole style often used in industrial and military-grade applications where high power and reliability are prioritized over miniaturization.
Replacement Considerations
Check for equivalent parts with matching 91V Zener voltage, 10W power rating, and DO-213AA package. Verify pinout compatibility and thermal resistance characteristics. Ensure substitute components meet the same -65°C to 175°C operating temperature range and ±5% tolerance specifications.
