Product details

NexFET N-channel — what the 1.6 mOhm buys you

The Texas Instruments CSD16401Q5T is a NexFET N-channel MOSFET rated for 25 V drain-to-source and 100 A continuous drain current at 25 °C case temperature. The 1.6 mOhm max on-resistance at 40 A with a 10 V gate drive suits low-voltage, high-current synchronous buck converter and OR-ing / load-switch applications.

Lifecycle and sourcing

The CSD16401Q5T is listed as Active and ROHS3 compliant. For dual-sourcing resilience, the NexFET family includes several 25 V N-channel parts in the VSON-CLIP package, but pin compatibility should be verified against the specific footprint and gate-drive requirements.

Frequently asked questions

What is the Rds(on) of CSD16401Q5T?

The maximum on-resistance is 1.6 mOhm at 40 A drain current with a 10 V gate drive. At 4.5 V gate drive the Rds(on) is higher — the datasheet curve shows the typical value.

What is the closest pin-compatible alternative to CSD16401Q5T?

Within the TI NexFET family there are several 25 V N-channel parts in the 8-VSON-CLIP package, such as the CSD16403Q5A and CSD16404Q5A. These differ in Rds(on) and gate charge — verify the specific rating against your design's conduction loss and switching loss budget before substituting.
