Product details

The Texas Instruments CSD16322Q5 is a 25 V N-channel NexFET™ power MOSFET in a surface-mount package. It is designed for low-voltage DC-DC conversion, load switching, and battery protection in industrial, telecom, and automotive environments. The 5 mOhm typical on-resistance at 20 A keeps conduction losses low, and the 9.7 nC gate charge at 4.5 V means a modest gate driver can switch it fast.

The 5 mOhm Rds(on) at 20 A and 8 V gate drive determines I²R loss and heatsink requirement. The 3.1 W package limit at 25 °C ambient gives headroom with good board layout.

Gate drive and switching speed

Gate charge is 9.7 nC at 4.5 V, and the drive voltage range for minimum Rds(on) is 3 V to 8 V. Input capacitance Ciss is 1365 pF at 12.5 V Vds.

No direct pin-compatible second source from another brand is listed in the official cross-reference data, so if dual-sourcing is a requirement, qualify a functional equivalent through your own bench validation.
