MA4P4002F-1091T

RF Diode Overview

The MA4P4002F-1091T is a high-power PIN diode from the MACOM MELF and HIPAX series, designed for switch and attenuator applications requiring high power handling and low distortion. It features a fully passivated silicon chip with a thick intrinsic region and long carrier lifetime, enclosed in a rugged ceramic package. The device utilizes full-face bonding on both anode and cathode to minimize thermal resistance and series loss. This specific part number indicates a magnetic package variant in the rectangular SMQ Metal Electrode Leadless Faced (MELF) format, suitable for surface mount assembly.

RF Diode Feature Summary

• High power handling capability with low insertion loss
• Low distortion characteristics due to thick I-region design
• Hermetically sealed leadless MELF package for reliable surface mounting
• Passivated chip construction ensuring extremely low reverse bias leakage current

RF Diode Applications

• Low distortion attenuators
• Surface mount RF switches
• Cellular radio antenna switching systems

RF Diode Procurement Notes

Verify the exact ordering suffix against the manufacturer's official documentation to confirm package type and magnetic properties. Ensure that the required quantity matches the standard tape and reel packaging specifications provided by the supplier. Confirm RoHS compliance status if environmental regulations apply to the final assembly process.

RF Diode Selection Notes

Select this component when designing circuits that require high voltage ratings up to 200 V combined with low series resistance. Consider the MELF package geometry for automated pick-and-place assembly processes. Evaluate the thermal resistance parameters relative to the expected power dissipation levels in the target application environment.

RF Diode Part Context

This device belongs to the MA4P4000 series within the broader MACOM MELF and HIPAX product family. It shares common design technologies such as full-face chip bonding and passivation techniques found across the series. The part is distinct from non-magnetic variants and axial leaded HIPAX packages, offering a specialized surface-mount solution for high-frequency applications.

RF Diode Replacement Considerations

The MA4P4001F-1091T serves as a similar alternative within the same package style but offers a lower maximum reverse voltage rating of 100 V compared to the 200 V rating of the MA4P4002F-1091T. Designers must verify that the reduced voltage tolerance meets the circuit requirements before substitution.
