Notes:
3. Device mounted on FR-4 substrate PC board, 2oz copper, with minimum recommended pad layout.
4. Device mounted on FR-4 substrate PC board, 2oz copper, with 1inch square copper plate.
5. I AR and E AR rating are based on low frequency and duty cycles to keep T J = 25°C
6. Short duration pulse test used to minimize self-heating effect.
7. Guaranteed by design. Not subject to product testing.
