Overview
The Microchip Technology 1N4740AE3/TR13 is a Zener diode designed for voltage regulation applications. It features a nominal Zener voltage of 10 V with a tolerance of ±5%. The device operates in the DO-41 axial through-hole package and dissipates up to 1 W of power. Key electrical parameters include a maximum reverse leakage current of 10 µA, a Zener impedance of 7 Ohms, and a test current of 25 mA. It supports a wide operating temperature range from -65°C to +175°C.
Feature Summary
- Provides stable voltage regulation at a nominal 10 V level
- Capable of handling 1 W power dissipation in an axial leaded package
- Engineered for reliable operation across extended industrial temperature ranges
Applications
- General-purpose voltage reference circuits
- Overvoltage protection stages
- Power supply output regulation
Procurement Notes
Verify the specific suffix against official Microchip documentation to confirm tape-and-reel packaging versus bulk availability. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the exact part number with authorized distributors to confirm current manufacturing status and avoid obsolete stock.
Selection Notes
Select this component when a standard 10 V regulation point is required in through-hole designs. Consider the 1 W power rating and thermal management needs for high-current environments. Verify that the ±5% voltage tolerance aligns with circuit precision requirements before finalizing the design.
Part Context
This part belongs to the 1N47xx series of general-purpose Zener diodes manufactured by Microchip Technology. The series is widely used in electronic circuits for basic voltage clamping and reference tasks. The 'E3' suffix typically indicates lead-free and RoHS-compliant construction within the manufacturer's portfolio.
Replacement Considerations
Compatible substitutes include the 1N4740A from other manufacturers such as onsemi or Vishay, provided they meet the same 10 V, 1 W, and DO-41 specifications.
