Diode Bridge with Integrated
Adjustable OVP Circuit
Description
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.
