Overview
The Microchip Technology 1N4736AUR is a single Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 6.8 V with a tolerance of +/- 10%. The device operates in an axial DO-41 package and dissipates up to 1 W of power. Key electrical characteristics include a maximum reverse leakage current of 10 uA, a Zener impedance of 3.5 Ohms, and a test current of 37 mA. It functions within a temperature range of -65 C to +150 C.
Feature Summary
- Provides stable voltage regulation at a nominal 6.8 V potential
- Capable of handling 1 W power dissipation in standard axial packaging
- Maintains low reverse leakage current for efficient operation
Applications
- Voltage reference circuits requiring stable DC levels
- Overvoltage protection in electronic systems
- General-purpose voltage regulation tasks
Procurement Notes
Verify the specific suffix configuration against official datasheets to ensure compatibility with design requirements. Confirm RoHS compliance status and lead times directly with authorized distributors or the manufacturer. Ensure ordering quantities align with factory packaging specifications to avoid fulfillment delays.
Selection Notes
Select this component when a 6.8 V regulation point is required with moderate power handling capabilities. Consider the axial DO-41 form factor for through-hole mounting constraints. Evaluate thermal management needs given the 1 W dissipation rating and operating temperature limits.
Part Context
This part belongs to the standard 1N47xx series of Zener diodes manufactured by Microchip Technology. These components are widely used in discrete semiconductor applications for basic voltage clamping and reference purposes. The 1N4736 variant specifically targets the 6.8 V market segment within the broader family.
Replacement Considerations
Cross-reference with other manufacturers' 1N4736 equivalents such as those from ON Semiconductor or Vishay. Verify pinout compatibility and electrical parameter tolerances before substitution.
