• Improved Efficiency Due to:
♦ Low Base Drive Requirements (High and Flat DC Current Gain h )
FE
♦ Low Power Losses (On−State and Switching Operations)
♦ Fast Switching: t = 100 ns (typ) and t = 3.2 ms (typ)

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.
