| Details |
| ~~~~~~~ |
| |
| The 20V NMOS FET has similar construction to the 11V/16V NMOS FET, with several differences: |
| |
| - Longer drift region |
| - Longer poly gate |
| - Larger W/L |
| - Devices placed in pairs (drain in center, sources on outside) |
| |
| Major model output parameters are shown below and compared against the EDR (e-test) specs |
