MADP-007455-12790T

RF Diode Overview

The MADP-007455-12790T is a silicon PIN diode from the MACOM SMPP series, housed in an SC-79 (Case Style 1279) surface-mount package. It features a reverse voltage rating of 100 V and a maximum total capacitance of 0.35 pF at 50 V. The device exhibits a maximum series resistance of 3.0 Ohms at 10 mA forward current and a nominal minority carrier lifetime of 1.0 µs with an I-region thickness of 2.0 mils. Designed for RF control applications, it supports an operating temperature range of -65°C to +125°C and handles up to 30 dBm CW incident power.

RF Diode Feature Summary

• General-purpose silicon PIN diode suitable for both switching and attenuator functions
• SC-79 surface-mount plastic package optimized for automatic pick-and-place assembly
• Low distortion characteristics due to specific intrinsic region engineering

RF Diode Applications

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

RF Diode Procurement Notes

Verify the complete part number including the trailing 'T' suffix to confirm tape and reel packaging configuration. Ensure the ordering code matches the SC-79 case style 1279 designation. Confirm RoHS compliance status and matte tin plating requirements against current project specifications before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a balance between low capacitance and moderate series resistance is required for general-purpose RF control. The 100 V reverse voltage rating provides robustness for higher bias applications compared to lower-rated counterparts. Consider the 1.0 µs carrier lifetime for applications requiring specific recovery time characteristics in switching or attenuation modes.

RF Diode Part Context

This device belongs to the MACOM SMPP series of surface mount plastic PIN diodes. It shares the MA4P7455 family designation but utilizes the SC-79 package instead of SOT-23 or SOD-323 options. The series includes variants with different I-region thicknesses tailored for specific performance metrics such as low distortion or low resistance.
