1N4738AP-AP

Overview

The MCC 1N4738AP-TP is a 1.0W Zener diode designed for voltage regulation applications. It features an 8.2V nominal Zener voltage with a 5% tolerance, housed in the DO-41G through-hole package. The device operates within a temperature range of -65°C to +200°C and maintains a maximum reverse leakage current of 10µA at 6V. Key electrical characteristics include a Zener impedance of 4.5 Ohms and a forward voltage of 1.2V at 550mA.

Feature Summary

• Provides stable voltage regulation using silicon junction technology
• Features a robust plastic encapsulated DO-41G axial leaded package
• Supports extended operating temperatures up to +200°C

Applications

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

Procurement Notes

Verify the specific suffix against official Micro Commercial Components documentation to confirm exact tolerance and testing specifications. Ensure the component matches the required DO-41G footprint and thermal ratings for your design. Cross-reference datasheets from authorized distributors to validate RoHS compliance status and availability before finalizing procurement plans.

Selection Notes

Select this component when a standard 8.2V regulation point is required in a through-hole configuration. The DO-41G package offers reliable mounting for general PCB assembly. Consider the 1W power dissipation rating and 5% voltage tolerance to ensure compatibility with circuit requirements. Verify that the high maximum operating temperature meets environmental constraints.

Part Context

This part belongs to the JEDEC-standardized 1N47 series of 1-watt Zener diodes. The 'AP' suffix typically denotes specific manufacturing lot or tolerance variations within the MCC product line. These components are widely used in industrial electronics for basic voltage clamping and reference tasks.

Replacement Considerations

Compatible substitutes include the onsemi 1N4738ATR and Nexperia 1N4738A,133. Both offer identical 8.2V regulation and DO-41 packaging. Verify pinout compatibility and thermal performance before substitution.
