HIGH-SPEED, HIGH-CURRENT SURGE PROTECTORS PMT/UMT (275) Series DESCRIPTION CP Clare’s PMT(275) and UMT(275) Series surge protectors (350-500V and 550-2500V respectively) provide a high level of protection from high-speed, high-current transient surges. These devices are constructed using a proprietary semiconductor junction process which results in nanosecond response times combined with peak current ratings in excess of 20kA. FEATURES s Fast impulse breakdown (≤125% of typical DC APPLICATIONS s s s s breakdown at 5kV/µs) s Tight DC breakdown voltage tolerance (± 10%) s Low capacitance Test equipment Video displays Medical electronics Instrumentation circuits STANDARD VOLTAGES Series PMT(275) DC Breakdown Voltage (typ) 350 400 450 500 550 600 650 750 800 850 1.0 1.5 2.0 2.5 (See detailed specifications for more information.)
