Unidirectional DC TVS Diodes
A unidirectional TVS diode avalanches for one voltage polarity and behaves as a forward-biased diode for the opposite polarity.

Product & engineering
Understand the product.
Polarity and surge-return routing determine protection behaviour; a pulse-power rating does not specify permissible continuous DC dissipation.
What turns activity into demand
Circuit topology defines rectification, switching, reference or transient-protection duty. Usable demand is constrained by voltage, current, recovery, capacitance and the available thermal path.
The commercial boundary
Material, junction function and package are separate specifications. A similar exterior cannot establish the reverse-voltage, pulse or switching boundary.
Which voltage and pulse conditions define protection?
Polarity and surge-return routing determine protection behaviour; a pulse-power rating does not specify permissible continuous DC dissipation.
