The layered body formed from the variable resistance layer (102), the semiconductor layer (103), and the second electrode (104) functions as a bidirectional diode element (106).
The electrostatic protection comprises a bidirectional diode (electrostatic protective device) constituted by an MOS transistor connected between an electrode (pad) for connecting the external terminal and a common potential line.
For a use of the triac as a gradator, one often resorts to a network RC, associated if necessary with a diac, bidirectional diode allowing to obtain a dephasing even more important.
A voltage-triggered protective circuit comprising a diac (16) in series with a bi-directional zener diode (14) is connected between the output side of the transistorised surge protection device (18) and a surge sinking node (15).
The fourth region of the first device and the first region of the second device are for connection a cathode terminal of the bi-directional diode.
