10.6 A continuous drain — sizing the load budget
The 10.6 A figure is the thermal limit at the case; actual current in a 85 °C ambient with a moderate heatsink will be lower, but it gives you headroom for a 3–5 A steady-state load in a power supply or motor drive. The TO-220-3 through-hole package (PG-TO220-3) lets you bolt it to a heatsink with a single screw — the tab is the drain, so the heatsink path is electrically live. Plan an insulating pad or a mica washer if the heatsink is chassis-grounded.
Rds(on) — the number that sets the conduction loss
Rds(on) for the IPP60R380P6 is 380 mOhm typical at 25 °C junction temperature. That is the on-resistance that determines I²R heating in the channel. At 5 A drain current, expect about 9.5 W conduction loss at 25 °C — a manageable figure for a TO-220 with a modest heatsink, but it rises with temperature, so budget derating for a 100 °C junction.
Wide temperature range — fits industrial and automotive environments
The 150 °C max junction is the absolute ceiling for silicon — keep the thermal design below 125 °C for long-term reliability.
