POWER-GATE solid state rectifier-relays are designed to behave like an ideal diode, allowing current to flow in a uni-directional fashion from Source to Load when a trigger signal is applied via the provided control harness. When trigger voltage is removed, the device will behave like a non-conducting open relay.
The rectifier-relay is a modification of our standard single rectifier device. With the single rectifier, current can always flow from anode to cathode whenever the device is forward-biased (even if the device loses its ground connection which is required for the internal circuit board to operate properly); there is no way to stop the current flow in this case. The rectifier-relay has a modified MOSFET array that allows the user to trigger the device between two modes: 1) With the trigger not activated, current flow will be blocked in both directions (analogous to the operation of the bi-directional relay), even if the device is forward biased, and 2) with the trigger activated, the device will act like our standard single rectifier (ideal diode), allowing current to flow from anode-to-cathode when the device is forward biased, and blocking current from flowing from cathode-to-anode when the device is reverse biased. You can think of the rectifier-relay as internally consisting of a bi-directional relay in series with a single rectifier.
