1N4741AP-TP

Overview

The MCC 1N4741AP-TP is a single silicon 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 supports a maximum power dissipation of 1 W and operates within a temperature range of -65 °C to +200 °C. Key electrical characteristics include a maximum reverse leakage current of 5 µA, a Zener impedance of 10 Ohms, and a forward voltage of 1.2 V at 200 mA. It is housed in the DO-41 axial leaded package.

Feature Summary

• Provides stable voltage regulation with a nominal 11 V Zener breakdown.
• Supports high thermal stability with an operating junction temperature up to 200 °C.
• Features low reverse leakage current for efficient standby performance.
• Constructed with a rugged DO-41 axial package for through-hole mounting.

Applications

• Voltage reference circuits requiring precise 11 V levels.
• Overvoltage protection stages in power supply inputs.
• Clamping applications for transient voltage suppression.
• General-purpose voltage regulation in electronic equipment.

Procurement Notes

Verify the specific suffix AP against official Micro Commercial Components documentation to confirm exact mechanical and electrical tolerances. Confirm RoHS compliance status via the manufacturer's environmental declaration. Ensure the DO-41 package dimensions match the target PCB footprint requirements before finalizing procurement decisions.

Selection Notes

Select this component when a 1 W through-hole Zener diode with an 11 V nominal rating is required. Consider the 10 Ohm Zener impedance for dynamic regulation needs. Evaluate the 200 °C maximum junction temperature for high-thermal environments. Compare the 5 µA leakage current against circuit sensitivity requirements to ensure adequate isolation.
