Under any set of conditions, do not exceed the specified current rating or a junction temperature of 150°C. Repetitive ±3.0 A Peak, < 3 μs ±6.0 A Package Power Dissipation PD See Thermal Characteristics – – Operating Ambient Temperature TA Range S –20 to 85 ºC Maximum Junction Temperature TJ(max) Fault conditions that produce excessive junction temperature will activate the device’s thermal shutdown circuitry. These conditions can be toler- ated but should be avoided. 150 ºC Storage Temperature Tstg –55 to 150 ºC |
