Pin	Signal	Direction	Function
1	S1 Current terminal	Current terminal	Source. It sets the gate-voltage reference and is the intrinsic diode anode.
2	G1 Input	Input	Gate. Drive with the rated voltage relative to its own source.
3	S2 Current terminal	Current terminal	Source. It sets the gate-voltage reference and is the intrinsic diode anode.
4	G2 Input	Input	Gate. Drive with the rated voltage relative to its own source.
5	D2 Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.
6	D2 Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.
7	D1 Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.
8	D1 Current terminal	Current terminal	Drain. It connects to the switched load and is the intrinsic diode cathode.
