What this small-signal MOSFET does on your board
The 2N7002H6327XTSA2: Infineon OptiMOS N-Channel MOSFET, 60 V drain-source, 300 mA continuous drain, SOT-23-3 package.
60 V Vdss and 300 mA Id — the voltage and current ceiling
The 60 V drain-source rating gives comfortable headroom for 12 V and 24 V industrial buses, automotive battery lines, and 48 V telecom rails. Derate for temperature: at 85°C ambient the current capability drops roughly linearly, so budget 200 mA or less for reliable operation in a warm enclosure.
3 Ohm Rds(on) and 0.6 nC gate charge — what they mean for drive and heat
Maximum on-resistance is 3 Ohm at 500 mA with 10 V gate drive. Gate charge is 0.6 nC at 10 V.
Supplier device package is PG-SOT23.
