At a 50 kHz switching frequency the average gate-drive current needed is 4 mA — a standard totem-pole driver handles that easily. The input capacitance of 5550 pF at 25 V drain-source determines the rise time the driver sees; a 1 A peak driver charges the gate in about 55 ns, fast enough to keep switching losses in check for hard-switched bridges up to 100 kHz. The gate-source voltage is clamped at ±20 V maximum, so a 10 V or 12 V gate-drive rail is safe. The threshold voltage is specified at 2.4 V maximum with 83 µA drain current — that low threshold means the part is fully enhanced with a 5 V logic-level gate drive, though the 4.5 V minimum drive voltage for rated Rds(on) means you want at least 5 V to get the on-resistance down. ## Junction temperature — 175°C buys headroom Operating junction temperature range is -55°C to 175°C. That 25°C margin over the more common 150°C max matters in a motor-drive or battery-charger enclosure where ambient air can hit 85°C and the heatsink is size-constrained. The 125 W power dissipation at case temperature is the absolute ceiling; real designs derate from that number based on the thermal resistance of the heatsink and the airflow. ## Through-hole TO-220 — mounting and thermal interface The IPP70N10S3L12AKSA1 comes in a PG-TO220-3-1 package, a standard three-lead through-hole TO-220. The tab is the drain — the PCB copper pad under the screw hole or a clip-on heatsink carries the thermal path. For 70 A continuous, a heatsink is not optional; the junction-to-case thermal resistance is low enough that a modest extruded aluminium sink with forced air keeps the junction under 125°C at full load. ## Lifecycle and compliance It is ROHS3 compliant. The OptiMOS series is a mature, widely-sourced platform; stock turns through independent distribution are routine.","metaTitle":"Infineon IPP70N10S3L12AKSA1 N-Channel MOSFET","metaDescription":"Infineon OptiMOS N-channel MOSFET, 100V Vdss, 70A continuous drain, 12.1mOhm Rds(on) at 10V.
