69819070-P4SMA550A
SMD TVS diode, Unidirectional, 400 W, 495 V, DO-214AC, P4SMA550A
The maximum voltage that a diode can withstand in the reverse direction without breaking down or avalanching.If this voltage is exceeded the diode may be destroyed. Diodes must have a peak inverse voltage rating that is higher than the maximum voltage that will be applied to them in a given application.
