The SM3407SRL is a MOSFET P Trench, 30V, 4.3A, 3V toggle switch manufactured by SPS. It is a SOT-23-3 RoHS-compliant package, which offers high on-resistance of 60 mΩ @ 4.3A and 10V, and a low off-state current of 250uA. This device is ideal for applications requiring low power switch, such as battery operated applications. It also helps to reduce EMI/RFI in switching applications.
