| Non Magnetic SMQ HIPAX PIN Diode V 1.00 MA4P7446F-1091T Features Non-Magnetic Package Suitable for MRI Applications Rectangular MELF SMQ Ceramic Package Hermetically Sealed Lower Rs for Lower Series Loss n Longer L for Lower Intermodulation Distortion n Lower Cj for Higher Series Isolation n Higher Average Incident Power Handling Capability n n n n Description The MA4P7446F-1091T is a surface mountable PIN diode in a Non-Magnetic ( patent pending ) Metal Electrode Leadless Faced (MELF) package. The device incorporates M/A-COM's proven HIPAX technology to produce a low inductance ceramic package with no ribbons or whisker wires. The package utilizes M/A-COM's new non- magnetic plating process to provide an extremely low permeability, hermetically sealed package. Incorporated in the package is a passivated PIN diode that is full face bonded on both the cathode and anode of the chip to maximize surface area for lower electrical and thermal resistance. The MA4P7446F-1091T has been comprehensively characterized both electrically and mechanically to ensure repeatable and predictable performance. This MA4P7446F-1091T Non-Magnetic device is similar in electrical performance to the MA4P4002F-1091T and MA4P4006F-1091T Magnetic part numbers. Designed for Automated Assembly These SMQ PIN diodes are designed for high volume tape and reel assembly. The rectangular package design provides for highly efficient automatic pick and place assembly techniques. The parallel flat surfaces are suitable for key jaw or vacuum pickup techniques. All solder able surfaces are tin plated and compatible with reflow and vapor phase soldering methods. Enviornmental Capability HIPAX devices are applicable for use in industrial and military applications and can be screened to meet the environmental requirements of MIL-STD-750, MIL-STD-202 as well as other military standards. The table below lists some of the MIL-STD 750 tests the device is designed to meet. Applications The diodes are well suited for use in low loss, low distortion, and high power switching circuits applicable for high magnetic field environments from HF through UHF frequencies. The lower thermal resistance of this device provides excellent higher average performance at RF power incident levels up to 500 watts CW. This device is designed to meet the most rigorous electrical and mechanical requirements of MRI testing environments.
