MADP-007448-0287AT

RF Diode Overview

The MADP-007448-0287AT is a single silicon PIN diode from the MACOM SMPP series, housed in an SOT-23 (Case Style 287) surface-mount package. It serves as a general-purpose component for microwave control circuits, functioning effectively as both a switch and an attenuator. The device features a reverse voltage rating of 100 V and a maximum total capacitance of 0.25 pF at 50 V. Its nominal series resistance is 2.0 Ohms at 10 mA forward current, with a carrier lifetime of 0.4 µs and an I-region thickness of 0.6 mils. The part supports an operating temperature range from -65°C to +125°C.

RF Diode Feature Summary

• General-purpose design suitable for both switching and attenuation applications
• Low distortion characteristics due to optimized intrinsic region thickness
• Lead-free surface mount construction compliant with RoHS standards
• High isolation performance in series and shunt configurations

RF Diode Applications

• Microwave control circuits requiring low loss and high isolation
• RF switches operating through 3 GHz
• Attenuator circuits in infrastructure equipment
• CATV signal processing systems

RF Diode Procurement Notes

Verify the ordering suffix 'T' indicates tape and reel packaging for automatic assembly. Confirm the 'A' suffix corresponds to the specific SOT-23 case style variant. Ensure compliance with RoHS directives if required by the manufacturing process. Check datasheet specifications for absolute maximum ratings before integration.

RF Diode Selection Notes

Select this model when a balance between low capacitance and moderate series resistance is required for general-purpose RF control. The 0.4 µs carrier lifetime offers faster switching than higher-lifetime variants but provides lower distortion handling compared to thicker I-region devices. Suitable for applications where standard SOT-23 footprint constraints apply.

RF Diode Part Context

This component belongs to the MADP-007448 series within the broader SMPP product line. It shares the same electrical profile as the MA4P7447 and MADP-007155 series but is distinguished by its specific plastic package configuration. The series is designed to offer versatile performance for engineers needing reliable silicon PIN diodes in compact surface-mount formats.

RF Diode Replacement Considerations

The MA4P7447-287T is a direct equivalent in the same package with identical electrical parameters. The MADP-007155-0287T also shares the same series characteristics. Verify pinout compatibility and thermal dissipation requirements when substituting these parts.
