Product details

Package and mounting — the 8-VSON-CLIP footprint

The CSD18510Q5BT: The part comes in an 8-PowerTDFN (5x6 mm). The large exposed pad on the bottom is the drain connection and the primary thermal path — it must be soldered to a copper plane on the PCB, with sufficient vias to the inner layers, to get anywhere near the 156 W power dissipation rating. Surface-mount only; no through-hole option.

Lifecycle and compliance

ROHS3 compliant, no exemptions. The -55°C to 150°C junction-temperature range covers automotive under-hood and industrial environments where the PCB may see sustained heat.

Frequently asked questions

What package does CSD18510Q5BT use?

The package is an 8-PowerTDFN, also designated 8-VSON-CLIP (5x6 mm). It is a surface-mount package with an exposed drain pad for thermal management.

What is the closest pin-compatible alternative to CSD18510Q5BT?

The evidence does not list a direct pin-compatible second source or cross-reference. For a functional equivalent within the NexFET family, review TI's 40 V NexFET portfolio with similar Rds(on) and gate charge — package and pinout should be verified against the specific alternative datasheet.

Is CSD18510Q5BT RoHS compliant?

Yes, the part is ROHS3 compliant.
