Overview
The Microchip Technology 1N4740AP/TR8 is a single Zener diode with a nominal voltage of 10 V and a tolerance of +/- 5%. It features a power dissipation rating of 1.0 W and operates within a temperature range of -65 °C to +150 °C. The device has a maximum reverse leakage current of 10 µA, a Zener impedance of 7 ohms, and a test current of 25 mA. It is housed in an axial DO-41 package and supplied in tape and reel packaging.
Feature Summary
- Provides stable voltage regulation at a nominal 10 V level
- Designed for through-hole mounting in axial configurations
- Capable of handling 1.0 W power dissipation under specified conditions
Applications
- Voltage reference circuits requiring 10 V stability
- Overvoltage protection for low-voltage electronic systems
- Clamping applications in signal processing paths
Procurement Notes
Verify the specific suffix TR8 confirms tape and reel packaging when ordering. Confirm the manufacturer designation as Microchip Technology, noting historical associations with Microsemi or other entities in legacy documentation. Ensure the DO-41 axial package matches your PCB footprint requirements before finalizing procurement.
Selection Notes
Select this component when a 10 V Zener voltage with 5% tolerance is required. Consider the 1.0 W power rating and -65 °C to +150 °C operating range for thermal management. The axial DO-41 package dictates through-hole assembly methods. Verify compatibility with existing circuit designs regarding leakage current and impedance specifications.
Part Context
This part belongs to the standard Zener diode family, commonly used for voltage regulation and protection. The 1N47xx series is widely recognized in electronics for reliable performance in discrete form factors. The AP variant typically denotes specific tolerance and testing parameters defined by the manufacturer.
Replacement Considerations
Cross-reference with Vishay 1N4740A-TR or onsemi 1N4740A for similar electrical characteristics. Verify package compatibility and power ratings when substituting. Ensure voltage tolerance and temperature ranges meet application requirements.
