STK4065

No. 2148—2/9

°C, R

* It is guaranteed that load short causes no damage for 2 seconds. In actual applications, the thermal shutdown protector provides sufficient guarantee against load

short. However, refer to “Notes for Applying the STK4065”, because the saturation current varies with the thermal resistance of the heat sink.
