SAFE OPERATING AREA INFORMATION
FORWARD BIAS
There are two limitations on the power handling ability of a
transistor: average junction temperature and second breakdown. Safe operating area curves indicate IC – VCE limits of
the transistor that must be observed for reliable operation;
i.e., the transistor must not be subjected to greater dissipation than the curves indicate.
The data of Figure 7 is based on TC = 25_C; T
J(pk)
is
variable depending on power level. Second breakdown pulse
limits are valid for duty cycles to 10% but must be derated
when TC ≥ 25_C. Second breakdown limitations do not derate the same as thermal limitations. Allowable current at the
voltages shown on Figure 7 may be found at any case temperature by using the appropriate curve on Figure 9.
At high case temperatures, thermal limitations will reduce
the power that can be handled to values less than the limitations imposed by second breakdown.

REVERSE BIAS
Inductive loads, in most cases, require the emitter–to–
base junction be reversed biased because high voltage and
high current must be sustained simultaneously during turn–
off. Under these conditions, the collector voltage must be
held to a safe level at or below a specific value of collector
current. This can be accomplished by several means such as
active clamping, RC snubbing, load line shaping, etc. The
safe level for these devices is specified as Reverse Biased
Safe Operating Area and represents t he voltage–current
condition allowable during reverse biased turn–off. This rating is verified under clamped conditions so that the device is
never subjected to an avalanche mode. Figure 8 gives the
RBSOA characteristics.

DYNAMIC DESATURATION
DYNAMIC DESATURATION
The SCANSWITCH series of bipolar power transistors are
specifically designed to meet the unique requirements of horizontal deflection circuits in computer monitor applications.
Historically, deflection transistor design was focused on minimizing collector current fall time. While fall time is a valid
figure of merit, a more important indicator of circuit performance as scan rates are increased is a new characteristic,
“dynamic desaturation.” In order to assure a linear collector
current ramp, the output transistor must remain in hard saturation during storage time and exhibit a rapid turn–off transition. A sluggish transition results in serious consequences.
As the saturation voltage of the output transistor increases,
the voltage across the yoke drops. Roll off in the collector
current ramp results in improper beam deflection and distortion of the image at the right edge of the screen. Design
changes have been made in the structure of the SCANSWITCH series of devices which minimize the dynamic desaturation interval. Dynamic desaturation has been defined in
terms of the time required for the VCE to rise from 1.0 to
5.0 volts (Figures 13 and 14) and typical performance at optimized drive conditions has been specified. Optimization of
device structure results in a linear collector Current ramp, excellent turn–off switching performance, and significantly lower overall power dissipation.

EMITTER–BASE TURN–OFF ENERGY
Typical techniques for driving horizontal outputs rely on a
pulse transformer to supply forward base current, and a
turn–off network that includes a series base inductor to limit
the rate of transition from forward to reverse drive. An alternate d rive scheme h as been used t o characterize the
SCANSWITCH series of devices (see Figure 15). This circuit
produces a ramp of base drive, eliminating the heavy overdrive at the beginning of the collector current ramp and
underdrive just prior to turnoff produced by typical drive strategies. This high performance drive has two additional impor-
tant 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 current flow as in a
series base 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 process of generating the ramp stores rather than dissipates energy. Tailoring the amount of e nergy stored in T1 to the
amount of energy , EB
(off)
, that is required to turn–off the output transistor results in essentially lossless operation. [Note:

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.
