CSD87333Q3D Description

Short technical summary and product information.

The CSD87333Q3D is a 30V, 15A dual N-channel MOSFET array from Texas Instruments, part of the NexFET power block family. It is designed for synchronous buck and boost applications, offering high efficiency and high-frequency operation up to 1.5 MHz. The device integrates two asymmetrical N-channel MOSFETs in a half-bridge configuration, optimized for 5V gate drive.

Key electrical specifications include a maximum drain-source on-resistance of 14.3 mΩ at 4A and 8V, a maximum gate charge of 4.6 nC at 4.5V, and an input capacitance of 662 pF at 15V. The power block achieves 94.7% system efficiency at 8A with a power loss of 1.5W.

The device is housed in a compact 8-PowerTDFN package (3.3mm x 3.3mm) with surface mount mounting. It supports an operating temperature range of -55°C to 150°C and is RoHS compliant, halogen free, and lead-free. Typical applications include motor control and power supply circuits.
