1N4741A-TP

Overview

The MCC 1N4741A-TP is a silicon planar Zener diode housed in a DO-41 glass package. It provides a nominal Zener voltage of 11 V with a 5% tolerance and a maximum power dissipation of 1 W at 50°C ambient temperature. The device operates within a temperature range of -65°C to +200°C. Key electrical characteristics include a test current of 23 mA, a maximum reverse leakage current of 5 µA at 8.4 V, and a dynamic impedance of 8 Ω.

Feature Summary

• Utilizes silicon planar technology for stable voltage regulation
• Encased in a hermetic glass package for environmental protection
• Features low reverse leakage current for high reliability
• Supports operation up to a junction temperature of 200°C

Applications

• Voltage reference circuits
• Overvoltage protection systems
• General-purpose voltage regulation

Procurement Notes

Verify the authenticity of the component by purchasing exclusively from Micro Commercial Components or their authorized distributors. Counterfeit parts are prevalent; unauthorized sources do not provide warranty coverage or traceability. Confirm that the ordering suffix matches the required packaging format, such as tape and reel or bulk, prior to finalizing procurement orders.

Selection Notes

Select this component when a precise 11 V regulation point is required with tight 5% voltage tolerance. Ensure the application environment supports the specified operating temperature range up to 200°C. Verify that the circuit design accommodates the 1 W power dissipation limit and applies appropriate derating factors if ambient temperatures exceed 50°C.

Part Context

This part belongs to the 1N47 series of general-purpose Zener diodes manufactured by Micro Commercial Components. The series covers a wide voltage range from 3.3 V to 75 V. The 'TP' suffix indicates RoHS compliance and lead-free finish, distinguishing it from standard non-compliant variants within the same product family.

Replacement Considerations

Cross-reference with other manufacturers offering the 1N4741A specification. Ensure equivalent packages, voltage tolerances, and thermal ratings are maintained during substitution.
