2 A2 passive Anode of diode 2 (isolated diode paired with pin 5 cathode); VRRM 75 V, IO 150 mA, IFSM 2.0 A.
3 A3 passive Anode of diode 3 (isolated diode paired with pin 4 cathode); VRRM 75 V, IO 150 mA, IFSM 2.0 A.
4 K3 passive Cathode of diode 3 (paired with pin 3 anode); forward voltage max 1.25 V at IF=150 mA.
5 K2 passive Cathode of diode 2 (paired with pin 2 anode); forward voltage max 1.25 V at IF=150 mA.
6 K1 passive Cathode of diode 1 (paired with pin 1 anode); forward voltage max 1.25 V at IF=150 mA.
