2N7002KT1G

2N7002KT1G is an onsemi N-channel MOSFET in a SOT-23-3 package, rated at 60 V drain-source voltage and 320 mA continuous drain current, with on-resistance of 1.6 Ω at 10 V gate drive and an ESD-protected gate — the K-grade of the industry-standard 2N7002 small-signal switch for load switching, level shifting and signal routing. The K is the selection point: it is onsemi's ESD-gate variant of the family, the code to specify where gate handling robustness matters in assembly and field service. Selection advice: 2N7002-class parts from different makers are not datasheet copies of each other — the Vishay 2N7002K-T1-GE3 also listed here is rated 300 mA and 2 Ω, against this part's 320 mA and 1.6 Ω, so qualify the code you actually buy against its own maker's datasheet and do not swap codes on a released BOM without checking on-resistance at your gate voltage. At 1.6 Ω this is a signal and light-load switch, not a power device. Parameters verified against onsemi documentation.
