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 3C/W (TO-220). Thermal resistance for TO-220 case to ambient temperature is
50C/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.
