Product details

8 Ohm Rds(on) — conduction loss at low current

The STP2N105K5 has 8 Ohm maximum on-resistance at 750 mA and 10 V gate drive. Gate charge is only 10 nC at 10 V, so a simple gate driver or even a microcontroller PWM output can switch it at moderate frequencies without excessive drive current.

Junction temperature range and package

Housed in a TO-220-3 through-hole package with the tab as the drain, it mounts to a heatsink via the mounting hole — the thermal pad area under the tab sets the junction-to-case thermal resistance.

It is ROHS3 compliant with no exemptions.
