CSD17578Q3A Description

Short technical summary and product information.

The CSD17578Q3A is a 30V N-Channel NexFET power MOSFET from Texas Instruments, designed for high-efficiency power conversion. It offers a maximum drain-source voltage of 30V and a continuous drain current of 20A at 25°C ambient (54A at case temperature). The device features a low on-resistance of 7.3mΩ maximum at 10V gate drive and 9.4mΩ at 4.5V, enabling reduced conduction losses. With a typical gate charge of 7.9nC and input capacitance of 1590pF, it supports fast switching. The logic-level gate threshold (1.5V typical) allows direct drive from low-voltage controllers. The MOSFET is avalanche rated and operates over a junction temperature range of -55°C to 150°C. It is housed in a compact surface-mount 8-PowerVDFN package (3.3mm x 3.3mm), making it suitable for space-constrained designs. The device is Pb-Free, RoHS3 compliant, and halogen free.
