Product details

Gate drive and switching parasitics

Gate charge is 68 nC at 10 V, and input capacitance Ciss is 2530 pF at 25 V Vds. The 4.5 V drive voltage for minimum Rds(on) means it can run from a 5 V logic-level gate signal, though the full 10 V drive delivers the rated 6.4 mOhm. The ±20 V Vgs max gives headroom for gate-drive overshoot in hard-switching topologies.

Thermal budget and package

Maximum power dissipation is 136 W at the case, but the junction-to-ambient thermal path through the PG-TO252 (DPak) surface-mount package limits practical continuous dissipation on a standard PCB.

Frequently asked questions

What is the exact Rds(on) of SPD50N03S2L at 10 V?

Maximum Rds(on) is 6.4 mOhm at 50 A drain current with 10 V gate drive. This is the guaranteed limit at 25 °C junction temperature; actual on-resistance increases with temperature per the normalised curve in the datasheet.
