I have read somewhere that a TVS is nothing else than a robust Zener diode. My application requires using 300V zener diodes (that may exist but do not pop up so easily), but TVS at 300V are very common and inexpensive. My question is: can TVS diode be used to regulate the voltage in reverse mode like a usual Zener diode would do ?

  • \$\begingroup\$ An ideal one could. In practice, I'd question the precision of the breakdown voltage; it seems unlikely that TVS diodes, which are made to stop fault conditions, would require as precise a breakdown voltage as Zener/avalanche diodes, which are made to be voltage references. \$\endgroup\$ – Hearth Apr 5 at 13:29
  • \$\begingroup\$ Google "The XY Problem stack exchange", read that and decide whether you might want to explain why you think you need a 300V zener diode. \$\endgroup\$ – K H Apr 6 at 3:42
