C3SS Series Asymmetrical Operation



 


Description:

The C3SS data series of 5 pin solid state protector modules are designed to provide superior transient and power fault protection for most data line applications, including RS-232. The C3SS is an ideal replacement for applications using 30 volt, 600 & 1500 Watt avalanche and zener diodes. The 30 volt SIDACTOR technology's 75 Amp l0xl000 psec surge rating is over twice that of a typical 1500 Watt, 30 volt avalanche diode or zener diode. With a capacitance rating < l00pf of capacitance at 1Mhz, 20VDC bias, the C3SS is dramatically superior to the > 550pf normally found with diode technologies. Normal breakdown voltage operation for the C3SS is 27-36 VDC with a nominal rating of 30 VDC.

Application:

The C3SS series is well suited to most data line protection applications including RS-232, where added protection is required. These products also provide superior protection for most digital (low loop voltage) telecom applications.
