Overview
The Taiwan Semiconductor Corporation 1N4741A R1G is a single silicon Zener diode designed for voltage regulation and protection applications. It features a nominal Zener voltage of 11 V with a tolerance of ±5%. The device is rated for a maximum power dissipation of 1 W and utilizes the DO-204AL (DO-41) axial through-hole package. It operates within a temperature range of -65 °C to 175 °C.
Feature Summary
- Provides stable voltage reference and regulation in electronic circuits
- Utilizes robust DO-41 axial leaded package for through-hole mounting
- Engineered for high reliability with low leakage current characteristics
Applications
- Voltage regulation in power supply circuits
- Overvoltage protection for sensitive components
- Clamping and surge suppression applications
Procurement Notes
Verify the specific suffix 'R1G' against official Taiwan Semiconductor documentation to confirm packaging configuration, as standard part numbers may vary by distributor. Ensure compliance with RoHS directives if required by the application. Cross-reference datasheets from authorized sources to validate electrical parameters before procurement.
Selection Notes
Select this component when an 11 V Zener reference is required in a through-hole design. Consider the 1 W power rating and DO-41 package constraints for thermal management. Verify that the ±5% tolerance meets circuit precision requirements compared to tighter tolerance alternatives.
Part Context
This component belongs to the 1N47xxA series of Zener diodes manufactured by Taiwan Semiconductor. These devices are widely used in general-purpose electronics for voltage stabilization. The 1N4741A variant specifically targets the 11 V market segment within the broader family of axial-leaded silicon rectifiers and regulators.
Replacement Considerations
Compatible substitutes include the Nexperia 1N4741A and Panasonic 1N4741A_R2_10001. Verify pinout compatibility and ensure equivalent electrical ratings such as Zener voltage, power dissipation, and package dimensions before substitution.
