Recommendation(1) Flat surface heat sink, thermal compound andsufficient mount screw torque (0.5Nm-0.6Nm) will
be necessary for well heat transfer.
(2) In rush current protection application as charge
current limitation resistor, sufficient power derating
will be necessary.
(3) Flammability is UL94V-0,(4) Recommended screw torque is 0.5-0.6Nm.
