Notes:
Operating conditions that exceed the Absolute Maximum Ratings could result in permanent damage to the device.
Thermal Resitivity specification assumes a Au/Sn eutectic die attach onto a Au-plated copper heatsink or rib.

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. This product has be tested to Class 1A (> 250V but < 500V) using JESD22 A114, Human
Body Model, and to Class A, (< 200V) using JESD22 A115, Machine Model..
ASSEMBLY INSTRUCTIONS
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 1.0 mil (0.025 mm) gold wire. Stage
temperature should be 250-260
°
C.
