... Please note, that in case of an inverse current no protection function is active. The power dissipation is higher compared to normal operation in forward mode due to the voltage drop across the drain-source diode ( with reverse polaritiy). If this mode lasts for a too long time the device can be destroyed. Infineon Technologies AG Symbol each of the two channels =-40° ...
