RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm the exact package type and packaging format. Ensure that the selected variant matches the required thermal and electrical specifications for the intended application environment. Cross-reference the datasheet revision to confirm current manufacturing parameters and compliance status before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a general-purpose silicon PIN diode is required for RF control applications. Consider the 0.25 pF capacitance and 2.0 Ohm series resistance at 10 mA bias for circuit impedance matching. Evaluate the thermal derating coefficients if operating near the absolute maximum ratings. Confirm compatibility with standard surface mount reflow soldering profiles during the design phase.

RF Diode Part Context

This device belongs to the MACOM SMPP series of surface mount plastic PIN diodes. The series offers various configurations including single diodes, common cathode/anode pairs, and series tees across multiple package styles such as SOT-23, SC-79, and SOD-323. The MADP-007448 series specifically targets applications needing balanced performance between switching speed and isolation without specialized low-resistance or ultra-low-capacitance requirements.

RF Diode Replacement Considerations

Direct substitutes within the same family include MADP-007448-0287AT (SOT-23), MADP-007448-11410T (SOD-323), and MADP-007448-12790T (SC-79). These variants share identical electrical characteristics but differ in physical footprint and mounting configuration. Verify pad layout compatibility when transitioning between package styles.
