摘要： A surge protection circuit having an open circuit voltage surge protector, such as a gas discharge tube (GDT), a closed circuit current surge protector, such as a thermistor, and a thyristor. The GDT has a breakdown voltage that is at least a first defined amount higher than an anticipated highest peak voltage. The thermistor has a series resistance associated with a series resistance of electrical equipment being protected and a breakdown voltage that is at least a second defined amount higher than an impulse voltage (voltage required to excite the GDT based on the breakdown voltage) for the GDT. The thyristor has a rated peak current at least a third defined amount greater than a peak current for the thermistor.
