| 3 | G2 | input | Gate of the second N-channel MOSFET; the datasheet gives VGSS of ±12 V as the absolute maximum gate-source voltage for the device. |
| 4 | D2 | passive | Drain of the second N-channel MOSFET; the datasheet gives ID of 3 A continuous and IDM of 12 A pulsed drain current for the device. |
| 5 | S1 | passive | Source of the first N-channel MOSFET; the datasheet gives VDSS of 20 V as the drain-source voltage limit for the device. |
| 6 | D1 | passive | Drain of the first N-channel MOSFET; the datasheet gives ID of 3 A continuous and IDM of 12 A pulsed drain current for the device. |
