Overview
The Microchip Technology 1N4741AP/TR12 is a single silicon Zener diode housed in the DO-204AL (DO-41) axial through-hole package. It provides a nominal Zener voltage of 11 V with a tolerance of ±5%. The device is rated for a power dissipation of 1 W and operates within a temperature range of -65°C to +150°C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 8 ohms, and a test current of 23 mA.
Feature Summary
- Provides stable voltage regulation via Zener breakdown mechanism
- Designed for high-temperature operation up to 150°C
- Utilizes hermetically sealed glass axial construction
Applications
- Voltage reference circuits
- Overvoltage protection
- Clipping and clamping applications
Procurement Notes
Verify the specific suffix TR12 indicates reel packaging when sourcing. Confirm RoHS compliance status as documentation may vary by manufacturing batch or region. Ensure the supplier provides valid traceability documents matching the Microchip Technology manufacturer part number to guarantee component authenticity and quality standards.
Selection Notes
Select this component for designs requiring an 11 V reference with ±5% precision. The DO-41 package supports standard through-hole mounting processes. Verify that the circuit's thermal environment remains within the specified -65°C to +150°C operational limits to maintain performance reliability and prevent junction overheating during continuous operation.
Part Context
This component belongs to the 1N47xxA series of single Zener diodes manufactured by Microchip Technology. The series offers various voltage options within the same physical footprint, allowing for standardized board layouts across different voltage requirements while maintaining consistent mechanical and thermal characteristics for design flexibility.
Replacement Considerations
The 1N4741AP-TP shares identical electrical specifications but may differ in environmental ratings. The 1N4741AP/TR8 from Microchip Technology serves as a functional substitute with adjusted packaging format. Cross-reference datasheets to confirm compatibility regarding temperature ranges and package dimensions before implementation.
