EMITTER±BASE TURN±OFF ENERGY, EB(off)
Emitter±base turn±off energy is a new specification included on the SCANSWITCH data sheets. Typical techniques for driving horizontal outputs rely on a pulse transformer to supply forward base current, and a turnoff network that includes a series base inductor to limit the rate of transition from forward to reverse. An alternate drive scheme has been used to characterize the SCANSWITCH series of devices (see Figure 2). This circuit ramps the base drive to eliminate the heavy overdrive at the beginning of the collector current ramp and underdrive just prior to turn±off observed in typical drive topologies. This high performance
MJW16212
drive has two additional important advantages. First, the configuration of T1 allows Lb to be placed outside the path of forward base current making it unnecessary to expend energy to reverse the current flow as in a series based inductor. Second, there is no base resistor to limit forward base current and hence no power loss associated with setting the value of the forward base current. The ramp generating process stores rather than dissipates energy. Tailoring the amount of
energy stored in T1 to the amount of energy, EB(off), that is required to turn the output transistor off results in essentially
lossless operation. [Note: B+ and the primary inductance of T1 (LP) are chosen such that 1/2LPlb2 = EB(off).]

Figure 16. 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.
