Bourns® TCS™ High-Speed Protectors are typically used in conjunction with low capacitance TVS devices to form an extremely low let-through energy barrier to excessive voltages or currents during surge events which may damage high-speed, low voltage driver and receiver components. By limiting the maximum current to a safe level, a Bourns® TCS™ device offers superior protection for very high data rate differential lines against faults caused by short circuits, induction and lightning surges.

The Bourns® TCS™ DL Series High-Speed Protector products contain a dual, well matched, low resistance, bidirectional and very high-speed Transient Current Suppressor device.

The Bourns® TCS™ High-Speed Protectors are provided in a space-saving, surface mount DFN package meeting industry standard requirements such as RoHS and Pb Free solder reflow profiles.
