Isolated Stud PIN Diode

The HIPAX series of PIN diodes are designed for usage in switch and attenuator applications requiring high power handling and low distortion. These diodes incorporate a fully passivated PIN diode chip resulting in an extremely low reverse bias leakage current. The semiconductor technology utilized in the HIPAX families draws on MACOM ’s substantial experience in PIN diode design and wafer fabrication. The result is a device which has a thick I-region and long carrier lifetime while maintaining low series resistance and capacitance values. The chips used in the HIPAX PIN diodes are enclosed in a rugged ceramic package and is full face bonded to metal pins on both the anode and cathode. The result is a low loss PIN diode with low thermal resistance due to symmetrical thermal paths.

The MADP-07001B-1458WN is a BeO isolated packaged PIN diode well suited for MRI applications requiring a series diode but needing excellent power handling and heat management. The package leads are gold plated and compatible with both leaded and lead free solder attach processes. The base stud is OFHC copper which gives good heat management due to its high thermal conductivity
