CSD17578Q3AT Description

Short technical summary and product information.

The CSD17578Q3AT is an N-Channel MOSFET from Texas Instruments designed for low-voltage power switching applications. It features a drain-source voltage rating of 30V and a continuous drain current of 20A at ambient temperature. The device offers a low on-resistance of 7.3mOhm maximum at 10V gate drive, enabling efficient power conversion.

Key electrical characteristics include a gate threshold voltage of 1.9V maximum at 250µA, a gate charge of 22.2nC at 10V, and an input capacitance of 1590pF at 15V. The maximum power dissipation is 3.2W at ambient temperature and 37W at case temperature. The operating junction temperature range is -55°C to 150°C.

The MOSFET is housed in a surface-mount 8-PowerVDFN package with a supplier device package of 8-VSONP (3x3.3mm). This compact package is suitable for space-constrained designs. The device is RoHS3 compliant (unverified) and has an MSL rating of 1 (unlimited).
