On-resistance and gate charge — what they mean for the switching loop
The IPP070N08N3GXKSA1: The 7 mOhm Rds(on) at 10 V gate drive keeps conduction losses low in high-current paths. At 73 A, the voltage drop across the channel is roughly half a volt, which translates to manageable heat in the die when the part is properly heatsunk. The 56 nC gate charge at 10 V is moderate for this current class — it allows fast switching without demanding an aggressive gate driver, but the input capacitance of 3840 pF at 40 V means the gate-drive loop should be kept tight to avoid ringing.
Temperature range and package — field rework and thermal cycling
The -55°C to 175°C junction temperature range covers cold-start in outdoor telecom cabinets and sustained load in engine-bay environments without derating. The TO-220-3 package is a field-service favourite: a standard heatsink clip or screw mount, clear pinout, and easy to lift with hot air or a soldering iron if a replacement is needed. The PG-TO220-3 supplier designation matches the industry-standard footprint, so swapping in another TO-220 from the same class is straightforward.
Lifecycle and sourcing — active production, no LTB risk
The IPP070N08N3GXKSA1 carries an Active lifecycle status, meaning Infineon continues to manufacture it for new designs and ongoing production. There is no last-time-buy window to track. ROHS3 compliant, so it meets current EU and global environmental requirements.
