MA4P504-1072T

RF Diode Overview

The MA4P504-1072T is a silicon PIN diode housed in a lead-free MELF ceramic package (ODS-1072). It operates from 1 to 4000 MHz with a maximum reverse voltage of 500 V and total capacitance of 0.50 pF at -100 V. The device features a series resistance of 0.60 Ω at +100 mA and 100 MHz, supporting up to 7.5 W power dissipation on an infinite heatsink. Input IP3 exceeds 54 dBm at 1000 MHz with +10 dBm input power.

RF Diode Feature Summary

• High power handling capability suitable for high incident power environments
• Low loss and low distortion performance across the operating frequency range
• Low thermal resistance due to symmetrical thermal paths and full face bonding

RF Diode Applications

• RF switches
• Attenuators
• HF through UHF frequency circuits

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current documentation to confirm reel quantity and packaging specifications. Ensure compliance with RoHS directives and reflow soldering temperature profiles during assembly. Confirm that the ODS-1072 package dimensions match the target circuit board layout requirements.

RF Diode Selection Notes

Select this component for applications requiring high power handling and low insertion loss within the 1 to 4000 MHz range. Consider the 500 V reverse voltage rating for high-voltage switching scenarios. Evaluate the thermal management strategy based on the specified power dissipation limits in air versus attached to a heatsink.

RF Diode Part Context

This part belongs to the MACOM MA4P series of PIN diodes designed for surface mount assembly. It utilizes a metal electrode leadless faced (MELF) ceramic package which provides hermetic sealing and robust mechanical stability for automated pick-and-place manufacturing processes.

RF Diode Replacement Considerations

Consult MACOM application note M513 for detailed reel size information when sourcing replacements. Verify compatibility with existing Sn63/Pb37 or RoHS compliant solder alloys. Cross-reference electrical parameters such as series resistance and capacitance with alternative MELF packaged PIN diodes if direct substitution is required.
