Overview
The onsemi 1N4740A is a single silicon Zener diode housed in the DO-41-2 through-hole package. It provides a nominal Zener voltage of 10 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 10 µA, a Zener impedance of 7 Ohms, and a test current of 25 mA.
Feature Summary
- Provides stable voltage regulation via a single unidirectional Zener junction
- Features glass passivation for enhanced environmental protection
- Designed for high thermal stability with an extended operating temperature range
Applications
- Voltage reference circuits requiring precise potential levels
- Overvoltage protection stages in electronic systems
- Clamping applications for transient suppression
Procurement Notes
Verify the specific suffix designation against official manufacturer documentation to confirm exact mechanical or screening variations. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Ensure the procurement channel sources directly from authorized distributors to guarantee component authenticity and traceability.
Selection Notes
Select this component when a standard 10 V regulation point is required in through-hole designs. The DO-41 package accommodates standard PCB mounting techniques. Evaluate the 1 W power dissipation limit against expected thermal loads to ensure reliable operation under continuous stress conditions.
Part Context
This part belongs to the widely recognized 1N47 series of axial leaded Zener diodes. Manufactured by onsemi, it utilizes standard silicon planar technology. The component serves as a fundamental discrete semiconductor element for basic analog circuitry and power management tasks.
Replacement Considerations
Direct substitutes include Vishay 1N4740A and Nexperia 1N4740A,133. Verify that alternative manufacturers maintain identical 10 V nominal voltage and 1 W power rating specifications.
