I'm looking at the datasheet for a high-side switch (TI TPS2H160B)
I understand the Diode D to protect against revers voltage, but I don't understand what the TVS is doing in this context:
My understanding is that TVS are zeners, so conduct in reverse. But with the ordinary reverse voltage diode D there, how can the TVS be effective? It looks to me like D would still be the limiting factor, and it a TVS is going to be used it should be a single uni-directional TVS without D in series with it. Is this just a case of the datasheet being sloppy or am I not understanding it?
