1N4741A_T50R

Overview

The onsemi 1N4741A_T50R is a silicon planar Zener diode housed in a DO-41 axial glass case. It provides a nominal Zener voltage of 11 V with a tolerance of ±5%. The device dissipates up to 1 W at lead temperatures below 50°C and features a maximum dynamic impedance of 8 Ω at the test current of 23 mA. It operates within a temperature range of -65°C to +200°C.

Feature Summary

• Utilizes silicon planar technology for high reliability and low leakage current.
• Features a glass passivated junction enclosed in a DO-41 axial package.
• Designed for stable voltage regulation across a wide operating temperature range.

Applications

• Voltage reference circuits
• Overvoltage protection
• Clipping and clamping applications

Procurement Notes

Verify the specific T50R suffix against official documentation to confirm reel packaging specifications. Ensure the component matches the required 11 V rating and 1 W power dissipation limits. Confirm compliance with RoHS standards and check for any specific handling requirements associated with the axial leaded format during assembly.

Selection Notes

Select this component when an 11 V Zener voltage with 5% tolerance is required in a through-hole configuration. Consider the 1 W power dissipation capability and the -65°C to +200°C operating range. Verify that the DO-41 package dimensions fit the PCB layout constraints and that the 8 Ω dynamic impedance meets circuit stability requirements.

Part Context

This part belongs to the 1N47xx series of Zener diodes manufactured by onsemi. The series covers a broad voltage range from 3.3 V to 200 V, all sharing similar physical characteristics and construction methods. The 1N4741A specifically targets the 11 V segment of this lineup, offering consistent performance across various industrial and commercial electronic designs.

Replacement Considerations

Compatible substitutes include other manufacturers' 1N4741A variants in the DO-41 package. Ensure replacement parts maintain the same 11 V nominal voltage, 5% tolerance, and 1 W power rating. Verify that the dynamic impedance and leakage current specifications meet or exceed the original design requirements.
