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.

SECOND BREAKDOWN LIMITED

BONDING WIRE LIMITED

THERMALLY LIMIT @ TC = 25°C

There are two limitations on the power handling ability of

a transistor: average junction temperature and second

breakdown. Safe operating area curves indicate IC − VCE

operation i.e., the transistor must not be subjected to greater

dissipation than the curves indicate.

The data of Figure 5 is based on TJ(pk) = 150C; T C is

variable depending on conditions. Second breakdown pulse

limits are valid for duty cycles to 10% provided TJ(pk)

 150C. At high case temperatures, thermal limitations

will reduce the power that can be handled to values less than

the limitations imposed by second breakdown.
