55 V, 100 A — TO-220-3 power switch for PSU and motor drives
The IPP100N06S2L05AKSA2: The TO-220-3 through-hole package (PG-TO220-3-1) allows direct mounting to a heatsink with a screw or clip.
4.7 mOhm Rds(on) — conduction loss floor
Maximum on-resistance is 4.7 mOhm at 80 A drain current with 10 V gate drive. This is the number that sets the I²R heat in the pass element — at 80 A the conduction loss is under 30 W, which the 300 W package power rating (Tc) can handle with adequate heatsinking. The 4.5 V logic-level threshold lets a 5 V PWM signal from a microcontroller or gate driver turn the device fully on, though the 10 V drive delivers the lowest Rds(on).
Gate charge and switching speed
Total gate charge is 230 nC at 10 V. That is a substantial charge — the gate driver must source and sink this per switching cycle. At 50 kHz switching, the average gate current is about 11.5 mA; at 100 kHz it doubles to 23 mA. Pair with a driver rated for at least 2 A peak to keep the Miller plateau short. Input capacitance is 5660 pF at 25 V drain-source, consistent with a large-die device.
175 °C junction — thermal headroom
The 175 °C rating covers hot spots during overload transients in motor stall or short-circuit conditions.
