1N4747AP-TP

Overview

The MCC 1N4747AP-TP is a single Zener diode designed for surface-mount applications. It features a nominal Zener voltage of 20 V with a tolerance of ±5%. The device dissipates up to 1 W of power and operates within a temperature range of -55 °C to +150 °C junction temperature. Packaged in an SOD-123-2 form factor, it exhibits a maximum reverse leakage current of 5 µA and a Zener impedance of 22 Ohms at the test current.

Feature Summary

• Provides stable voltage regulation through a robust bonding structure suitable for precision circuitry.
• Engineered for high thermal stability across a wide operating temperature spectrum.
• Utilizes a compact surface-mount package to facilitate automated assembly processes.

Applications

• Voltage reference circuits requiring precise potential levels
• Overvoltage protection stages in sensitive electronic systems
• General-purpose clipping and clamping applications

Procurement Notes

Verify component authenticity by cross-referencing the manufacturer's part number against official datasheets. Confirm that the SOD-123-2 package dimensions align with your PCB footprint requirements. Ensure the specified electrical parameters meet your design constraints before finalizing procurement decisions.

Selection Notes

Select this component when a 20 V regulation point is required in a compact surface-mount format. Compare its low leakage current and specific impedance characteristics against alternative packages. Validate that the 1 W power rating accommodates the expected thermal dissipation in your target application environment.

Part Context

This component belongs to the 1N4747 series of Zener diodes manufactured by Micro Commercial Components. It represents a surface-mount evolution of traditional axial leaded designs, offering similar electrical performance in a smaller footprint. The 'TP' suffix typically denotes specific packaging or testing configurations defined by the manufacturer.

Replacement Considerations

Direct substitutes include other manufacturers' 1N4747 variants in SMD packages, such as those from onsemi or Microchip. Verify pinout compatibility and ensure equivalent voltage and power ratings are maintained during substitution.
