Unidirectional TVS as a diode?

cupoftea · Tuesday at 6:54 PM

Hi, for a unidirectional TVS like SMAJ33A, what are its diode characteristics like in the forward direction?
Does it have the forward recovery time of a general
purpose mains diode (eg 20ns or so) ? Does it have the reverse recovery characteristic of eg an ultra fast 75ns diode?

They generally have slightly higher forward drop - and are slow to recover - just like any zener/avalanche diode.

The forward turn on is relatively quick.
