| Technology | MOSFET (Metal Oxide) |
| Case | TO-252-3, DPak (2 Leads + Tab), SC-63 |
| Vgs(th) (Max) @ id | 2.5V @ 100µA |
| Rds on (Max) @ id, vgs | 14mOhm @ 38A, 10V |
| Gate charge (Qg) (Max) @ vgs | 48 nC @ 4.5 V |

The 140 W power dissipation at case temperature assumes the DPak tab is soldered to a PCB copper area sized to keep the junction below 175 °C at the operating current; a 1-inch-square 2-oz copper pad on a two-layer board is a typical starting point for 20 A continuous loads.
No last-time-buy risk or successor has been announced.
The part is also specified for 4.5 V gate drive, allowing logic-level switching.
No official successor has been announced. The IPD50R950CEAUMA1 is a 500 V CoolMOS part with a different voltage class and Rds(on) tier, not a functional second-source for this 100 V HEXFET.
