designed for continuous repetitive operation.
V
diode has to be limited by the connected load. Note that the power dissipation is higher compared to normal
operating conditions due to the voltage drop across the intrinsic drain-source diode. The temperature
protection is not active during reverse current operation! Input and Status currents have to be limited (see
max. ratings page 3 and circuit page 8).
