MOUNTING INFORMATION** 4–40 SCREW CLIP PLAIN WASHER HEATSINK COMPRESSION WASHER HEATSINK NUT Figure 6a. Screw–Mounted Figure 6b. Clip–Mounted Figure 6. Typical Mounting Techniques 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 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, Motorola does not recommend exceeding 10 in . lbs of mounting torque under any mounting conditions. **For more information about mounting power semiconductors see Application Note AN1040.
