Per-leg forward current 34 A @ TC=25 °C, VF ≈ 1.5 V typ @ IF=10 A, TJ=25 °C. Blocking voltage 1200 V (VRRM) with respect to the common cathode (pin 2 / CASE). |+| 2 | K | passive | Common cathode of both internal Schottky dies, electrically tied to the metal CASE / heatsink tab. Handles up to 68 A per device continuous forward current and blocks 1200 V (VRRM) against the two anodes (pins 1 and 3). Case must be treated as live at cathode potential for isolation and creepage design. |+| 3 | A2 | passive | Anode of internal Schottky die 2.
