MA4P504-132

RF Diode Overview

The MA4P504-132 is a silicon PIN diode chip from MACOM's Cermachip series, designed for high-voltage control applications. It features a hermetically sealed glass passivation process that encapsulates the junction area. Key electrical specifications include a reverse voltage rating of 500 V, a maximum capacitance of 0.20 pF at -100 V, and a nominal series resistance of 0.60 Ω at 10 mA forward current. The device has a carrier lifetime of 1 µs and an I-region length of 50 µm. Physically, it measures 20 x 20 mils with a thickness of 10.0 mils.

RF Diode Feature Summary

• Hermetically sealed construction using hard glass Cermachip passivation technology
• Optimized for low distortion in attenuator and switch circuits due to thicker I-regions
• Capable of controlling kilowatts of RF power within its voltage ratings

RF Diode Applications

• Broadband micro-strip hybrid assemblies
• High isolation microwave switching circuits
• Low loss RF attenuator designs

RF Diode Procurement Notes

Verify the specific ordering suffix against the manufacturer's current catalog to ensure correct package style availability. Confirm RoHS compliance status for the specific batch if required by assembly standards. Check for any recent datasheet revisions that may impact mounting temperature limits or handling procedures before finalizing procurement orders.

RF Diode Selection Notes

Select this component when a 500 V reverse voltage rating is required alongside low parasitic capacitance. The 1 µs carrier lifetime supports fast switching speeds suitable for broadband applications. Ensure the design accommodates the 20 x 20 mil physical footprint and utilizes appropriate die attachment methods such as eutectic solder or conductive epoxy for optimal thermal performance.

RF Diode Part Context

This part belongs to the MACOM Silicon PIN/NIP Diode Chips family, which offers extensive selections of I-region lengths. The Cermachip variant specifically provides hermetic sealing and high voltage capabilities up to 3,000 V across the broader product line. These chips are intended for integration into hybrid integrated circuits rather than standalone surface mount packages.

RF Diode Replacement Considerations

Direct substitutes within the same Cermachip series include the MA4P505-131 and MA4P506-131, which share similar 500 V ratings but differ in capacitance and series resistance characteristics. Alternative options from the Low Capacitance PIN category, such as the MA4P404-132, offer lower voltage ratings and different physical dimensions.
