ProTek Devices Intros High Current Voltage Suppressor SMDs for DC and AC Protection

SKCxxxCS Series Press Release

The New Series Consisting of Four Devices is Ideal for AC Line Protection and High-Power DC Bus Clamping, Remote Transmission Lines, and Industrial Wiring Applications.

ProTek Devices has introduced a new series of 10kA bidirectional transient voltage suppressors for circuit protection in DC and AC, in telecommunications infrastructure, and other similar industrial applications. These surface mount devices can be connected in a series or in parallel to create very high capability circuit protection solutions.

The SKCxxxCS series consists of four devices. The SKC-058CS has a reverse stand-off voltage of 58.0 volts, the SKC-066CS is 66.0 volts, the SKC-076CS is 76.0 volts, and the SKC-086CS is 86.0 volts. The devices provide a clamping voltage lower than the avalanche voltage. Thus, any voltage rise due to increased current conduction is contained to a minimum, providing the best possible protection level.

The series features compatibility with IEC standards 61000-4-2 (ESD): air plus or minus 30kV, contact plus or minus 30kV; with 61000-4-4 (EFT): 40A, 5/50ns; and with 61000-4-5 10kA (surge). They feature 1600 kilowatts peak pulse power (typical = 8/20 microseconds). Other features include a glass passivated junction and low slope resistance. The series also is RoHS complaint (exemption #7).
