table may damage the device. If any of these limits are exceeded, device functionality should not be assumed, 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).
