Product details

Gate drive and conduction loss — the numbers that decide the BOM

Drive voltage for minimum on-resistance is 4.5 V; maximum Rds(on) also specified at 1.8 V drive. 180 mOhm at 500 mA and 4.5 V. 1.4 nC gate charge at 4.5 V.

Package and mounting — plan the stencil

It sits flush on the PCB, so the solder paste stencil aperture and reflow profile need to match the small pad geometry.

Lifecycle and compliance — no obsolescence worry

The NexFET series from TI is a mature, widely used family, and this part number is still a standard catalog item.

Frequently asked questions

What is the closest pin-compatible alternative to CSD13381F4?

The CSD13381F4 is a unique 3-PICOSTAR footprint part. Within the same NexFET family, the CSD13380F4 is a similar N-channel 12 V FET but with a different on-resistance and current rating — verify the pinout and electrical specs before substituting. No direct second-source cross is listed in the official documentation.
