5.3.7 Protection during ESD or Over Voltage Condition
All logic pins have ESD protection. A dedicated clamp mechanism protects the logic IC against transient over
voltages. See Figure 20 for details.

In the case (V_S > max V_S(SC))&(V_S < V_SD(CL)), the output transistor is still operational and follows the input.
Parameters are no longer warranted and lifetime is reduced compared to normal mode. This specially impacts the
short circuit robustness, as well as the maximum energy E_AS the device can handle.
The BTF50060-1TEA provides Infineon^® SMART CLAMPING functionality, which suppresses non nominal over
voltages by actively clamping the over voltage across the power stage and the load. This is achieved by controlling
the clamp voltage V_SD(CL) depending on the junction temperature T_j and the load current I_L. See Figure 15 for
details. Please refer also to Chapter 5.1.2.
