MA4P404-30

RF Diode Overview

The MA4P404-30 is a silicon PIN diode from MACOM's fast switching series, designed for high power and voltage applications. It features a minimum reverse voltage of 250 V and a maximum capacitance of 0.40 pF at -10 V (1 MHz). The device exhibits a maximum series resistance of 0.70 Ω at 10 mA (500 MHz) and a nominal carrier lifetime of 100 µs. Packaged in style 30, it utilizes CERMACHIP® passivation for hermetic sealing. Operating temperature ranges from -65°C to +175°C, with absolute maximum ratings supporting stringent environmental conditions.

RF Diode Feature Summary

• Hermetically sealed CERMACHIP® glass encapsulation protects the active chip area
• Fast switching performance enabled by thin I-region design
• Low leakage current and low insertion loss characteristics
• High inherent reliability suitable for high RF voltage environments

RF Diode Applications

• RF microwave attenuator circuits
• High power switching control applications
• Military screened RF circuit designs

RF Diode Procurement Notes

Verify the specific package style availability before ordering, as specifications vary by case. Confirm RoHS compliance status through official channels. Ensure screening requirements match MIL-STD-750 standards if military grade is needed. Check soldering temperature limits for the selected package style to prevent damage during assembly.

RF Diode Selection Notes

Select this component when a 250 V minimum reverse voltage and 0.40 pF maximum capacitance are required. The 100 µs carrier lifetime supports moderate speed switching needs. Consider alternative packages like 120 or 258 if different parasitic capacitance values are necessary for the specific circuit layout.

RF Diode Part Context

This part belongs to MACOM's broad line of packaged PIN diodes, specifically the fast switching series. It shares the base MA4P404 chip technology with other variants but is distinguished by its specific electrical parameters and standard package style 30 configuration within the product family.

RF Diode Replacement Considerations

MA4P404-120 and MA4P404-258 are available alternatives using the same base chip but offering different package styles and associated parasitic capacitances. Verify that the alternative package meets the thermal and mechanical constraints of the original design.
