ORDERING INFORMATION
See detailed ordering and shipping information in the package
dimensions section on page 2 of this data sheet.
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 I
C
value is based upon JEDEC current gain requirements. The
3.0 A max value is based upon actual current鈭抙andling capability of the
device (See Figure 5).
2. Indicates JEDEC Registered Data for 2N4918 Series.
*Preferred
devices are recommended choices for future
use and best overall value.
