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 compression washer helps to maintain a con-

stant 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 pack-

age. However, in order to positively ensure the package integrity of the fully isolated device, ON Semiconductor does not recommend

exceeding 10 in

.

lbs of mounting torque under any mounting conditions.
