MA4PK2000

RF Diode Overview

The MA4PK2000 is a high-voltage PIN diode from the KILOVOLT series, rated for a maximum reverse voltage of 2000 Volts at 10 µA. It supports an instantaneous forward current of 25 Amperes and operates within a temperature range of -65°C to +175°C. The device features a typical series resistance of 0.10 Ω at 1.0-100 MHz with 0.5 A bias and a maximum parallel resistance of 5 kΩ at 100 MHz. Total capacitance is limited to 3.2 pF at 1 MHz and 100 V reverse bias. It utilizes float zone silicon with epitaxial P+ and N+ regions, housed in a hermetically sealed metal-ceramic Case Style 1027 package.

RF Diode Feature Summary

• Designed for low loss and low distortion performance in multi-kilowatt HF and VHF switch applications.
• Constructed with ultra-high resistivity float zone material and proprietary Cermachip glass passivation for reliability.
• Features rugged, hermetically sealed metal-ceramic packaging capable of withstanding extreme voltages and currents.
• Non-magnetic construction suitable for MRI applications up to 3 Tesla.

RF Diode Applications

• Multi-throw kilowatt switches
• Filter switches
• Antenna couplers
• Power amplifier bypass switches
• MRI switches

RF Diode Procurement Notes

Verify the specific case style and pinout configuration against the mechanical drawings before integration. Ensure handling procedures comply with ESD Class 1C requirements due to static sensitivity. Confirm that the installation temperature does not exceed 250°C for 30 seconds during soldering processes to prevent thermal damage to the junction or package seal.

RF Diode Selection Notes

Select the MA4PK2000 when a 2000 Volt reverse blocking capability is required rather than the 3000 Volt variant. Consider the Case Style 1027 form factor for direct mounting needs. Evaluate the 0.10 Ω typical series resistance and 3.2 pF maximum capacitance against system insertion loss and isolation requirements at the operating frequency.

RF Diode Part Context

This component belongs to the MACOM KILOVOLT PIN diode family, which includes the MA4PK300x series offering higher voltage ratings. The MA4PK2000 specifically targets applications requiring robust high-power switching elements where moderate voltage isolation is sufficient. It shares manufacturing technologies such as float zone processing and Cermachip passivation with its higher-voltage counterparts.

RF Diode Replacement Considerations

The MA4PK3000 serves as a higher voltage alternative within the same series but differs in breakdown characteristics. No direct cross-manufacturer equivalents are documented in the official datasheet. Verify compatibility with existing thermal management solutions if substituting with other high-power PIN diodes.
