*Indicates JEDEC Registered Data for 2N4918 Series.

(1) The 1.0 Amp maximum IC value is based upon JEDEC current gain requirements.

The 3.0 Amp maximum value is based upon actual current–handling capability of the

device (See Figure 5).

(2) Recommend use of thermal compound for lowest thermal resistance.

Preferred devices are ON Semiconductor recommended choices for future use and best overall value.
