Abstract: A protection circuit for use with an electronic DSL component having a tip connection and a ring connection, the protection circuit including: a first unidirectional transient-voltage-suppression (TVS) diode, having a negative TVS breakdown voltage BDV and diode forward voltage DV clamp, connected between Vcc and the tip connection of the DSL component; a second unidirectional TVS diode, having a diode forward voltage DV, connected between the tip connection of the DSL component and a negative ground clamp node; a third unidirectional TVS diode, having a negative TVS breakdown voltage BDV and diode forward voltage DV clamp, connected between Vcc and the ring connection of the DSL component; and a fourth unidirectional TVS diode, having a diode forward voltage DV, connected between the ring connection of the DSL component and the negative ground clamp node.
