1N4741A BK TIN/LEAD

Overview

The Central Semiconductor 1N4741A BK TIN/LEAD is a silicon planar Zener diode housed in a DO-41 through-hole package. It provides a nominal Zener voltage of 11 V with a 5% tolerance, tested at a current of 23 mA. The device dissipates up to 1.0 W at 50°C and operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a maximum dynamic impedance of 8 Ω, a reverse leakage current of 5 μA, and a maximum DC forward current of 8.4 mA.

Feature Summary

• Provides stable voltage regulation for industrial and commercial circuits
• Features high reliability and low leakage current design
• Utilizes a double guard ring construction for enhanced stability

Applications

• Industrial equipment power supplies
• Commercial electronic systems
• Computer circuitry voltage reference

Procurement Notes

Verify the specific ordering suffix required for your application. The datasheet indicates that adding 'TIN/LEAD' specifies leaded plating options. Confirm whether bulk or tape-and-reel packaging is needed, as availability may vary by manufacturer lot. Ensure compliance with environmental regulations if RoHS compliance is mandatory for your project requirements.

Selection Notes

Select this component when an 11 V regulation point is required in a standard axial leaded package. The 1 W power rating supports moderate current loads, while the wide operating temperature range suits demanding environments. Verify that the 5% voltage tolerance meets the precision requirements of the target circuit design.
