ProTek Devices has introduced an ultra-low-capacitance surge protection component for circuit protection in applications such as automotive infotainment systems, industrial cameras, Thunderbolt and more. The very low capacitance for the new PTB05-ULC is 0.15pF max (I/O to GND). Other applications include V-by-One HS, HDMI 2.0, and LVDS. The PTB05-ULC is designed to protect high speed data lines – up to eight – from electrostatic discharges (ESD) and electrical over-stress (EOS).

It is compatible with IEC standards 61000-4-2 (ESD): contact ±15kV, air ±15kV; with 61000-4-4 (EFT): 40A - 5/50ns; and with 61000-4-5 (surge): 7A - 8/20 micro seconds. It boasts a PCB single-connect and flow-through design. It also leverages solid-state silicon-avalanche technology. In addition, the PTB05-ULC is RoHS and REACH compliant.

The PTB05-ULC surge protector is now available and is provided in a molded DFN-18 package. Other key mechanical characteristics include lead-free pure-tin plating (annealed) and a solder reflow temperature of (pure-tin - Sn, 100) 260 to 270ºC.

It has a flammability rating of UL 94V-0. It is delivered on 12mm tape and reel, per EIA standard 481, in minimum quantities of 3,000. Pricing information and purchasing details can be had by contacting any authorised distributor, representative, or directly with ProTek Devices.
