MA4P4001F-1091T

RF Diode Overview

The MACOM MA4P4001F-1091T is a high-power PIN diode designed for switch and attenuator applications requiring high power handling and low distortion. It features a fully passivated silicon chip with a thick I-region and long carrier lifetime, enclosed in a rugged ceramic MELF surface mount package (Case Style 1091). The device offers a maximum reverse voltage of 100 VDC, a typical total capacitance of 2.2 pF, and a maximum series resistance of 0.5 Ω at 100 mA forward current. With a minimum parallel resistance of 20 kΩ and a minimum carrier lifetime of 20 µs, it provides robust performance for RF control circuits.

• Surface mount switches
• Cellular radio antenna switches

RF Diode Procurement Notes

Verify the specific ordering suffix against official documentation to confirm packaging details. The 'F' designation indicates a MELF surface mount package, while the '1091' suffix specifies the Case Style 1091 dimensions. Ensure the required quantity matches the standard tape and reel configuration of 500 pieces per reel as defined by the manufacturer's specifications.

RF Diode Selection Notes

Select this component when designing circuits that require high power handling combined with low insertion loss and minimal harmonic distortion. The 100 V reverse voltage rating and 0.5 Ω series resistance make it suitable for moderate voltage RF switching applications. Consider the MELF package geometry for automated surface mount assembly processes where low inductance is critical for high-frequency performance.

RF Diode Part Context

This part belongs to the MACOM MA4P MELF & HIPAX Series, which utilizes silicon PIN diode technology characterized by a thick intrinsic region and long carrier lifetime. The series includes various package options such as axial leaded HIPAX and rectangular MELF surface mount packages. These devices are engineered for predictable and repeatable performance in switch and attenuator applications from HF through UHF frequencies.

RF Diode Replacement Considerations

Within the same datasheet, the MA4P4001B-402 serves as an alternative using an axial leaded HIPAX package (Case Style 402) with identical electrical characteristics. For non-magnetic requirements, the MA4P4001BNM-402 is available in the axial leaded format. Direct MELF replacements within this specific voltage class are not listed in the provided documentation.
