Other features include a glass passivated junction and a bidirectional configuration. In addition, the TVS components provide a low slope resistance and a repetition rate (duty cycle) of 0.01%. They offer very low capacitance of 5 pf. The modules are all hazardous substance free and are compliant with RoHS (exemption #7).
The circuit protection components have typical trigger voltages ranging from 1100.0 to 1300.0 volts. Their maximum current ratings are 1.0, 2.5, 5, and 10KA, at 8/20 microseconds. The typical clamping voltage ranges from 1000.0 to 1300.0.
The devices and their AC or DC volts are: the PHCR660-1.0 and 440.0 VAC or 620.0 VDC; the PHCR880-1.0 and 660.0 VAC or 880.0 VDC; the PHCR660-2.5 and 440.0 VAC or 620.0 VDC; the PHCR880-2.5 and 660.0 VAC or 880.0 VDC; the PHCR660-5 and 440.0 VAC or 620.0 VDC; the PHCR880-5 and 660.0 VAC or 880.0 VDC; the PHCR660-10 and 440.0 VAC or 620.0 VDC; and finally the PHCR880-10 and 660.0 VAC or 880.0 VDC.
ProTek Devices’ PHCR series of high-powered TVS components are epoxy encapsulated devices. They offer high temperature soldering of 260°C / ten seconds at the terminals. They also have a flammability rating of UL 94V-0. The operating temperature is 85°C and the storage temperature range is -55 to +150°C.
