Figure 25. Typical Mounting Techniques
for Isolated Package
Laboratory tests on a limited number of samples indicate, when using the screw and compression washer mounting
technique, a screw torque of 6 to 8 in . lbs is sufficient to provide maximum power dissipation capability. The compres-
sion washer helps to maintain a constant pressure on the package over time and during large temperature excursions.
Destructive laboratory tests show that using a hex head 4–40 screw, without washers, and applying a torque in excess
of 20 in . lbs will cause the plastic to crack around the mounting hole, resulting in a loss of isolation capability.
Additional tests on slotted 4–40 screws indicate that the screw slot fails between 15 to 20 in . lbs without adversely
affecting the package. However, in order to positively ensure the package integrity of the fully isolated device, ON Semi-
conductor does not recommend exceeding 10 in . lbs of mounting torque under any mounting conditions.
