CSD87353Q5D Description

Short technical summary and product information.

The CSD87353Q5D is a NexFET power block from Texas Instruments, designed for synchronous buck applications. It integrates two N-channel MOSFETs in a half-bridge configuration, supporting a drain-to-source voltage of 30 V and a continuous drain current of 40 A at 25°C. The device features a logic level gate drive optimized for 5 V, with a maximum gate threshold voltage of 2.1 V at 250 µA. Gate charge is 19 nC at 4.5 V, and input capacitance is 3190 pF at 15 V. Power dissipation is rated at 12 W, with a power loss of 3.3 W at 25 A. The operating temperature range is -55°C to 150°C. The package is an 8-PowerLDFN (8-LSON 5 mm x 6 mm) surface mount package, offering ultra-low inductance for high-frequency operation up to 1.5 MHz. The device is RoHS compliant and halogen free, with lead-free terminal plating.
