How are protective diodes like TVS and Zener diodes shown in schematics?
In schematics, protective diodes such as TVS (Transient Voltage Suppressor) and Zener diodes are represented by the standard diode symbol with an additional element. For Zener diodes, a bent line at the cathode indicates voltage regulation. For TVS diodes, specific labeling is used to denote their transient suppression function.
