ON Semiconductor)
Medium-Power Plastic PNP
Silicon Transistors
. . . designed for driver circuits, switching, and amplifier
applications. These high–performance plastic devices feature:
Low Saturation Voltage —
VCE(sat) = 0.6 Vdc (Max) @ IC = 1.0 Amp
Excellent Power Dissipation Due to Thermopad Construction —
PD = 30 W @ TC = 25_C
Excellent Safe Operating Area
Gain Specified to IC = 1.0 Amp
Complement to NPN 2N4921, 2N4922, 2N4923
