VCE, COLLECTOR-EMITTER VOLTAGE (V)
Figure 50. Safe Operating Area − BC846
The safe operating area curves indicate IC−VCE lim-
its of the transistor that must be observed for reliable op-
eration. Collector load lines for specific circuits must fall
below the limits indicated by the applicable curve.
The data of Figure 50 is based upon TJ(pk) = 150°C; TC
or TA is variable depending upon conditions. Pulse
curves are valid for duty cycles to 10% provided TJ(pk)
≤ 150°C. TJ(pk) may be calculated from the data in Figure
49. At high case or ambient temperatures, thermal limita-
tions will reduce the power that can be handled to values
less than the limitations imposed by the secondary break-
down.
