Additional Details:

The TCK323G,LF(S comes in a small surface-mount package. It has a specific on-resistance (RDS(on)) value, which determines the voltage drop across the switch when it is conducting. The device operates within a specified voltage range and has a defined current limit for overcurrent protection. The 'LF(S' suffix often indicates that the component is lead-free and RoHS compliant.
