SL1122 Hybrid Arrester Series
Crydom Hybrid Arrester over-voltage surge protection device utilizing both tube semiconductor technologies, resulting package that delivers high current handling capability with speed silicon device. Compatible with standard tube arrester outlines, easily fitted exchanged into most board magazine connection systems, e.g., KroneLSA plus Quante 79126-506 magazines. electronic equipment becomes ever more complex, also become more sensitive therefore prone damage transients lower voltage levels. hybrid series provides protection sensitive electronic equipment where standard installation proves ineffective allowing much through voltage against ultra fast transients. precision matching semiconductor eliminates dv/dt switching delay normally associated with GDTs resulting lower clamping levels better protection while maintaining ability divert high-energy pulses (i.e., 8/20 µs). Already approved trialed British Telecom, hybrid provides ultimate over-voltage circuit protection.
Fast response, i.e., dv/dt switching delay High current handling capability, 8/20 defined 1000-4-5 High insulation resistance Typical capacitance series resistive element switching coordination Compatible with most connection systems Approved British Telecom systems Integral fail-safe
BENEFITS
Increased level protection sensitive electronic equipment need separate primary secondary protectors leakage current used most telecom electronic applications extra component cost modifications existing hardware Proven performance highest standards Prevents hazardous temperature conditions

voltage below voltage breakdown silicon diode. Under slow ramp rates (i.e., less than V/ms) breakdown Hybrid determined sparkover (typically ramp rate transient increases further dv/dt switching delay causes increased level through voltage before sparkover (would normally around kV/µs). this instance diodes clamp voltage (typically 200V) until sufficient time ionize, therefore breaking over diverting remaining energy pulse.
