2N4918_04 Datasheet, PDF (1/6 Pages) ON Semiconductor – Medium-Power Plastic PNP Silicon Transistors
2N4918 − 2N4920* Series
Preferred Device
Medium−Power Plastic PNP
Silicon Transistors
These medium−power, high−performance plastic devices are
designed for driver circuits, switching, and amplifier applications.
Features
• Pb−Free Package is Available**
• Low Saturation Voltage − VCE(sat) = 0.6 Vdc (Max) @ IC = 1.0 A
• Excellent Power Dissipation Due to Thermopad Construction,
PD = 30 W @ TC = 25_C
• Excellent Safe Operating Area
• Gain Specified to IC = 1.0 A
• Complement to NPN 2N4921, 2N4922, 2N4923

Maximum ratings are those values beyond which device damage can occur.
Maximum ratings applied to the device are individual stress limit values (not
normal operating conditions) and are not valid simultaneously. If these limits
are exceeded, device functional operation is not implied, damage may occur
and reliability may be affected.
1. The 1.0 A max IC value is based upon JEDEC current gain requirements. The
3.0 A max value is based upon actual current−handling capability of the
device (See Figure 5).
2. Indicates JEDEC Registered Data for 2N4918 Series.
