Overview
The onsemi 1N4741A-T50A is a silicon planar Zener diode designed for voltage regulation and reference 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 at 25°C ambient temperature. It utilizes the DO-41 axial leaded package, suitable for through-hole mounting. Key electrical characteristics include a maximum reverse leakage current of 5 µA and a Zener impedance of 8 Ω. The component operates within a temperature range of -65°C to +200°C.
Feature Summary
- Provides stable voltage regulation with a nominal 11 V Zener breakdown voltage.
- Engineered for high reliability with low leakage current specifications.
- Constructed using silicon planar technology for consistent performance.
- Designed for through-hole mounting in standard DO-41 axial packages.
Applications
- Voltage regulation in DC power supply circuits
- Reference voltage sources for analog signal processing
- Overvoltage protection for sensitive electronic components
Procurement Notes
Verify the specific suffix T50A against official datasheets to confirm tape-and-reel packaging requirements. Confirm RoHS compliance status and REACH SVHC declarations prior to integration. Check for obsolescence notices or lifecycle changes as availability may vary by region. Ensure thermal derating calculations align with the specified 1 W power dissipation limit at elevated temperatures.
Selection Notes
Select this component when an 11 V regulated reference is required in a through-hole design. Compare Zener impedance and leakage current against circuit sensitivity requirements. Verify that the DO-41 package dimensions fit the PCB layout constraints. Consider thermal management needs if operating near the maximum power dissipation rating.
Part Context
This part belongs to the 1N47xxA series of general-purpose Zener diodes manufactured by onsemi. The series offers a wide range of voltage options from 3.3 V to 200 V. These diodes are widely used in industrial and consumer electronics for basic voltage clamping and regulation tasks.
Replacement Considerations
Cross-reference with other manufacturers offering 1N4741A equivalents in DO-41 packages. Verify pinout compatibility and electrical parameter tolerances match the original design requirements before substitution.
