CPC7556 Diode Bridge with Integrated Adjustable OVP Circuit INTEGRATED CIRCUITS DIVISION Bridge Characteristics Parameter Description Rating Units Reverse Voltage 100 V Forward Current 240 mArms Thyristor Current 120 mA Features • Monolithic Construction • Surface Mount Package Applications • Telecommunications Protection Clamp • High Voltage Multiplexer/Switch • High Voltage ESD Clamp 100V Diode Bridge with an integrated Over-Voltage Protection (OVP) thyristor uses IXYS Integrated Circuits Division's High Voltage SOI technology. The CPC7556N integrated diode bridge offers protection from high voltage transients by means of an adjustable voltage clamp. The clamp performs two actions, first to limit the voltage across the diode bridge rectified outputs to a value determined by external resistors and the gate voltage and second to fully discharge the V+ to V outputs when the Gate’s trigger threshold is exceeded during the voltage limiting function. The rectified outputs are discharged as a result of the voltage fold-back function of the OVP device. Voltage fold back of the OVP circuit will continue until the current through the protector falls below the hold current threshold. Terminating the gate to V will disable the clamp voltage feature up to the thyristor’s off state voltage.
