MADP-007448-0287DT

RF Diode Overview

The MADP-007448-0287DT is a silicon PIN diode from the SMPP series, packaged in an SOT-23 (Case Style 287) surface mount plastic housing. It functions as a general-purpose component suitable for both switching and attenuator applications. The device features a reverse voltage rating of 100 V and a total capacitance of 0.25 pF measured at 50 V. Its nominal carrier lifetime is 0.4 µs with an I-region thickness of 0.6 mils. The part supports an operating temperature range from -65°C to +125°C and includes a Series Tee Reverse configuration.

RF Diode Feature Summary

• General-purpose design suitable for use as either switches or attenuators
• Series Tee Reverse configuration for specific circuit topologies
• Low distortion characteristics due to optimized intrinsic region thickness
• Lead-free surface mount package compliant with RoHS standards

RF Diode Applications

• Microwave control circuits requiring low loss and high isolation
• Current controlled attenuator circuits
• Automatic Gain Control (AGC) functions in infrastructure systems

RF Diode Procurement Notes

Verify the ordering suffix matches the required configuration. The 'DT' suffix indicates a Series Tee Reverse arrangement within the SOT-23 package. Confirm that the tape and reel packaging aligns with automated assembly requirements. Ensure the component meets the specific electrical tolerances defined in the datasheet for your application.

RF Diode Selection Notes

Select this model when a general-purpose PIN diode is needed for both switching and attenuation tasks. The 0.4 µs carrier lifetime offers a balance between speed and power handling. Consider the Series Tee Reverse topology if the circuit design requires this specific internal connection. Verify thermal derating coefficients against the expected RF and DC incident power levels.

RF Diode Part Context

This component belongs to the MACOM SMPP series of surface mount plastic PIN diodes. It shares the SOT-23 package form factor with other models like the MADP-007436 and MADP-007433 series. Unlike the MADP-007167 series which has a thicker I-region for lower distortion, this model provides a standard performance profile for general microwave control applications.

RF Diode Replacement Considerations

The MADP-007448-0287AT serves as the single diode equivalent in the same package. For common cathode configurations, consider the MADP-007448-0287FT. If a Series Tee forward configuration is acceptable, the MADP-007448-0287BT is available. Cross-reference electrical parameters such as capacitance and resistance before substitution.
