UNIT Inductive load turn off IDM = 25 A; VDD 20 V EDSM Non-repetitive clamping energy Tmb = 25C - 550 mJ EDRM Repetitive clamping energy Tmb 95C; f = 250 Hz - 60 mJ 1 Prior to the onset of overvoltage clamping. For voltages above this value, safe operation is limited by the overvoltage clamping energy. 2 A higher Tj is allowed as an overload condition but at the threshold Tj(TO) the over temperature trip operates to protect the switch. 3 All control logic and protection functions are disabled during conduction of the source drain diode. If the protection circuit was previously latched, it would be reset by this condition.
