For the following circuit I need a TVS. Ideally it should be a bidirectional TVS like SMBJ400CA. But since I only have access to its unidirectional version (SMBJ400A), considering the half wave nature of the circuit which blocks the current in the opposite direction, is it possible to use the unidirectional TVS instead?
Answer:
Thanks for your answers that gave me the idea and running the simulation confirmed the solution at least in theory. Please let me know if I'm wrong...
