Notes: * Ambient temperature will affect the current rating. For details, see the Thermal Ratings chart.
** Operating Frequency: 25 to 65 Hz (operates at 400 Hz with 6 times the offstate leakage)
***jc = Thermal resistance from internal junction to base. Maximum internal junction temperature is 110 °C.
