ABSTRACT:
A device for protecting I/O lines using PIN or NIP low capacitance transient voltage suppressors and steering diodes are disclosed. In an exemplary embodiment, a two (2) terminal device with a unidirectional low capacitance TVS diode (1101) and an anti-parallel LC PIN or NIP diode (1102) is disclosed. To provide for a low capacitance TVS with a forward conducting low-voltage characteristic, the LC PIN or NIP diode is placed anti-parallel to the unidirectional low capacitance TVS. This LC PIN or NIP diode must also have a reverse blocking voltage greater than the avalanche breakdown p-n junction voltage (V(BR)) of the unidirectional TVS.
