| 2 | S | passive | Source of the P-channel MOSFET, tied with the other source pins; VDS = -30V and ID = -50A continuous at TC=25℃. |
| 3 | S | passive | Source of the P-channel MOSFET, tied with the other source pins; VDS = -30V and ID = -50A continuous at TC=25℃. |
| 4 | G | input | Gate of the P-channel MOSFET; VGS maximum is ±20V, RDS(ON) < 15mΩ at VGS=-10V and < 25mΩ at VGS=-4.5V, threshold -1V to -3V. |
| 5 | D | passive | Drain of the P-channel MOSFET, tied with the other drain pins; VDS = -30V and pulsed drain current -80A. |
| 6 | D | passive | Drain of the P-channel MOSFET, tied with the other drain pins; VDS = -30V and pulsed drain current -80A. |
