| titleOfInvention | Surge protection device |
| abstract | An electrical surge protection device ( 12 ) confers protection to an output node ( 13 ) from electrical surges on a data or power line ( 10 ) incident on an input node ( 11 ). A transistorized surge protection device ( 18 ) is located in a current path between the input node ( 11 ) and the output node ( 13 ) and is configured to assume an isolating state in response to an over-current therethrough. 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 transistorized surge protection device ( 18 ) and a surge sinking node ( 15 ). The voltage-triggered circuit assumes a low-impedance state in response to an electrical surge at output terminal 13 . Consequently a surge current is passed through zener diode ( 14 ) and surge diac ( 16 ) to the surge sinking node. In response to the surge current the transistorized surge protection device ( 18 ) assumes a high impedance configuration thereby isolating output node ( 13 ) from input node ( 11 ). Since neither the zener diode and diac combination, nor the transistorized surge protection device ( 18 ) are subject to sustained surge associated currents, embodiments of the invention can be compactly packaged. |
