  • Publication number: 20110194220
    Abstract: An electronic system including an assembly with a protection clamp for discharging a portion of the incoming pulse, the un-discharged residual pulse (132) including a spike voltage (150, 202) for a first time duration (151, 203) followed by a bulk voltage (160, 302) smaller than the spike voltage for a second time duration (161, 303) greater than the first time duration; an integrated circuit device coupled with the board, the device allowing a peak current (211) at the insulator breakdown voltage (213), and including a pin protection clamp allowing a threshold current (311) at a threshold voltage (313) during the second time duration; and an isolation impedance integrated with the system for weakening the residual pulse, the impedance being the greater of a first resistor (220), determined by dividing the voltage difference between spike and insulator breakdown voltage through the peak current, and a second resistor (320), determined by dividing the voltage difference between the bulk and threshold voltage t
