Electrical Characteristics
Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating Conditions.
Note 2: Thermal resistance without a heat sink for junction to case temperature is 3˚C/W (TO-220). Thermal resistance for TO-220 case to ambient temperature is
50˚C/W.
Note 3: These parameters are guaranteed and 100% production tested.
Note 4: To ensure constant junction temperature, low duty cycle pulse testing is used.
