Working Principle

The SBR30A45CTB-13 is an enhancement-mode, bidirectional switch with built-in body diode and operates with input voltages of up to 20 V. It can effectively control current and voltage flow in either directions in ICs, logic gates, and power supplies.

The device consists of a junction field-effect transistor (JFET) integrated with a body diode. The integrated diode is connected between the drain and source terminals, while the gate terminal is connected to a voltage source. Whenever the gate voltage is equal or above the threshold voltage, the diode conducts current.

When the gate voltage is less than the threshold voltage, the circuit behaves like an open switch, which means that no current can flow through it. This allows the device to be used for applications like AC output circuits for computer power supplies, synchronous rectification circuits, LED driver circuits, and more.

The SBR30A45CTB-13 is a highly efficient device with low on-state resistance and low RDS(on). Additionally, the device is rated for operation in high-temperature applications.
