Notes:

6. Pulse-testing techniques maintain junction temperature close to ambient temperature; thermal effects must be taken into account separately.

The discharge function offers a resistive discharge path for the external storage capacitor for limited time.

8. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper, with minimum recommended pad layout.

9. Device mounted on 2” x 2” FR-4 substrate PCB, 2oz copper, with minimum recommended pad on top layer and thermal vias to bottom layer ground

plane.

10. Device mounted on 1"x1" FR-4 substrate PCB, 2oz copper, with minimum recommended padon top layer and thermal vias to bottom layer ground.
