60 V, 3 A PNP in SOT-89-3
The 2STF2360 is a PNP bipolar transistor rated for 60 V collector-emitter breakdown and 3 A continuous collector current, housed in the SOT-89-3 (TO-243AA) surface-mount package. With a DC current gain minimum of 160 at 1 A, 2 V, it holds useful beta into the ampere range — the saturation voltage stays at 500 mV max at 150 mA base drive and 3 A collector, so the on-state drop is predictable for a medium-current switch.
Switching speed and dissipation ceiling
Transition frequency is 130 MHz, which places this part in the general-purpose switching band — fast enough for DC-DC converter drive stages and relay coil drivers, but not a dedicated RF transistor. Maximum power dissipation is 1.4 W, and the junction temperature limit is 150 °C. In a SOT-89-3, the copper pad area on the PCB sets the effective thermal resistance — a minimal footprint will derate the usable power well below the 1.4 W ceiling.
