Microchip Technology, Inc. RF PIN Diode UMX5601SM

The UMX5601TM PIN diode series was designed to provide ultra low magnetic PIN diodes for in bore surface coil applications associated with higher field strength (3T and greater) MR scanners. These PIN diodes produce the minimum artifacts (magnetic field distortions) available in the industry, today. The diodes have been tested in magnetic fields of ±7 Tesla. The UMX5601 PIN diodes have a magnetic moment at 7 T of 4E-8 (J/T). The diodes are offered in a surface mount package. The SM package utilizes a round end cap to mark the anode. The cathode is square. The fully passivated PIN diode chip is full face metallurgically bonded to shortened high conductive pins for lower thermal and electrical resistances. The PIN diodes feature low forward bias resistance and high zero bias impedance. The UMX5601 PIN diodes are characterized at 64, 128, and 300 MHz. The UMX5601SM meets RoHS requirements per EU Directive 2002/95/EC.
