2N4921 Datasheet, PDF (1/8 Pages) ON Semiconductor – 1 AMPERE GENERAL PURPOSE POWER TRANSISTORS 30 WATTS

ON Semiconductor⁾
Medium-Power Plastic NPN
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 PNP 2N4918, 2N4919, 2N4920
