Overview
The Microchip Technology 1N4682 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 3.0 V with a standard tolerance of 5%. The device operates in a through-hole DO-7-2 package and supports a maximum power dissipation of 500 mW. Key electrical characteristics include a maximum reverse leakage current of 7.5 uA, a forward voltage of 1.1 V at 200 mA, and a test current of 50 uA. It functions within an operating temperature range from -65 C to +175 C.
Feature Summary
- Provides stable voltage regulation across a broad operating current and temperature range
- Constructed with glass axial-leaded DO-35 (DO-7) encapsulation for durability
- Offers guaranteed maximum voltage regulation performance
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify the specific suffix requirements against the official datasheet before ordering. Confirm that the selected variant meets all necessary environmental and reliability standards for the intended application. Ensure compatibility with existing PCB footprints and thermal management strategies during the procurement process.
Selection Notes
Select this component based on its 3.0 V Zener voltage and 500 mW power rating. Consider the DO-7 package size for through-hole mounting constraints. Evaluate the -65 C to +175 C operating temperature range against environmental conditions. Compare leakage current specifications if low standby power consumption is critical for the design.
Part Context
This part belongs to the 1N4678 thru 1N4717 series of 0.5 watt Zener Voltage Regulators. The series provides a selection of voltages from 1.8 to 43 volts in standard 5% tolerances. These components are widely used in general-purpose electronic circuits requiring reliable voltage stabilization.
Replacement Considerations
Consult the official datasheet for confirmed substitute part numbers. Verify pinout compatibility and electrical parameter equivalence before substitution.
