MA4SPS402 TM Rev V6 SURMOUNT PIN Diode RoHS Compliant Features Surface Mount No Wire Bonding Required Rugged Silicon-Glass Construction Silicon Nitride Passivation Polymer Scratch Protection Low Parasitic Capacitance and Inductance Higher Average and Peak Power Handling RoHS Compliant Description This device is a Silicon-Glass PIN diode chip fabricated with M/A-COM Technology Solutions pat- TM ented HMIC process. This device features two 1. Backside metal: 0.1 M thick. silicon pedestals embedded in a low loss, low dis- 2. Yellow hatched areas indicate backside ohmic gold persion glass. The diode is formed on the top of one pedestal and connections to the backside of the de- INCHES MM vice are facilitated by making the pedestal sidewalls DIM electrically conductive.
