If operation at 8V is considered then IDS must be reduced in order to keep the part within it's thermal power dissipation limits. Therefore VGS is restricted to < -0.5V.

Specially designed collets should be used where possible. PART NUMBER DESCRIPTION FPD7612 Die The recommended die attach is gold/tin eutectic solder under a nitrogen atmosphere. Stage temperature should be 280-290°C; maximum time at temperature is one minute. The recommended wire bond method is thermo-compression wedge bonding with 0.7 or 1.0 mil (0.018 or 0.025 mm) gold wire. Stage temperature should be 250-260°C. HANDLING PRECAUTIONS: To avoid damage to the devices care should be exercised during handling. Proper Electrostatic Discharge (ESD) precautions should be observed at all stages of storage, handling, assembly, and testing. These devices should be treated as Class 0 (0-250 V) as defined in JEDEC Standard No. 22-A114. Further information on ESD control measures can be found in MIL-STD-1686 and MILHDBK-263.
