TCS-DL Series - TCS™ Dual Transient Current Suppressors
General Information
®
™
The Bourns TCS DL Series High-Speed Protector products contain dual, well-matched,
low resistance, bidirectional, very high-speed Transient Current Suppressors. By limiting
®
™
the maximum current to a safe level, a Bourns TCS DL device offers superior protection
for very high data rate differential lines against faults caused by short circuits, induction
and lightning surges.

®
™
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
and currents during surge events which may cause damage to unprotected high-speed,
low voltage driver and receiver components.
TCS™ Device
®
™
The Bourns TCS High-Speed Protector is provided in a space-saving, surface mount
DFN package meeting industry standard requirements such as RoHS and Pb Free solder reflow profiles.

** Bourns follows the prevailing definition of “halogen free” in the industry. Bourns considers a product to be “halogen free” if (a) the Bromine (Br) content is 900 ppm or less;
(b) the Chlorine (Cl) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine (Cl) content is 1500 ppm or less.
Specifications are subject to change without notice.
The device characteristics and parameters in this data sheet can and do vary in different applications and actual device performance may vary over time.
Users should verify actual device performance in their specific applications.
