Description
This Power MOSFET is the latest development of
STMicroelectronics unique “single feature size”
strip-based process. The resulting transistor
shows extremely high packing density for low onresistance, moreover the double sides cooling
package with ultra low junction to case thermal
resistance allows to handle higher levels of
current.

The previous curve gives the single pulse safe operating area for unclamped inductive
loads, under the following conditions:
PD(AVE) =0.5*(1.3*BVDSS *IAV)
EAS(AR) =PD(AVE) *tAV
Where:
IAV is the allowable current in avalanche
PD(AVE) is the average power dissipation in avalanche (single pulse)
tAV is the time in avalanche
