Notes
(1) IO1 is rated at 3.0A @ TA = 55°C for PC boards where thermal resistance from mounting point to ambient is sufficiently controlled where
TJ(Max) does not exceed 175°C; This equates to R_θJA(PCB) ≤ 52°C/W. De-rate linearly 25mA/°C >55°C.
(2) TA = 25°C @ IO=3.0A and VRWM for ten 8.3mS surges at 1 minute intervals.
(3) PCB = FR4, 0.0625 Inch (1.59mm) thick, single layer, 1.0-Oz Cu, Pad Size, (1.0” x 1.0”), (645mm x 645mm) , horizontal in still air.
(4) PCB = FR4, 0.0625 Inch (1.59mm) thick, single layer, 1.0-Oz Cu, Pad Size, (0.070” x 0.155”)‡, (1.78mm x 3.94mm) ‡, horizontal in still air.
IO1 is rated at 1.5A @ TA = 55°C for PC boards where R_θJA(PCB) ≤ 120°C/W. De-rate at 12.5mA/°C above TA = 55°C in this case.
