ProTek Devices' SKCxxxCS series of transient voltage suppressors

These surface mount devices can be connected in a series or in parallel to create very high capability circuit protection solutions.

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). A data sheet is available with complete feature details.

Mechanical Details and Availability Information
The series is delivered in a SMTO-218 (tab) package with an approximate weight of just 6.5 grams. It has high temperature soldering of 260 degrees Celsius for 10 seconds at terminals. The operating and storage temperature is -55 to 150 degrees Celsius.

The SKCxxxCS series is available on tape suffix -T13, in minimum quantities of 400. Pricing information and purchasing details can be obtained by contacting any authorized worldwide distributor, representative, or directly with ProTek Devices. These sales resources are available throughout North America, Europe, Asia, South America, and more. Full contact information for all regions can be found at the company website.
