Product details

The CSD19532Q5B: The 4.9 mOhm maximum Rds(on) at 10 V gate drive sets the conduction loss floor — at 17 A the on-resistance is already specified, giving a clear I²R budget for the thermal design.

Package and thermal — 8-VSON-CLIP with exposed pad

The 8-PowerTDFN package, supplied as 8-VSON-CLIP (5x6 mm), has a large exposed drain pad on the bottom. The datasheet rates 3.1 W dissipation at 25 °C ambient (no heatsink) and 195 W at the case — the actual thermal performance depends on the PCB copper area soldered to the exposed pad. The clip construction reduces package resistance and inductance compared to wire-bonded alternatives, which matters for high-current switching loops.

No official second-source or pin-compatible cross-reference is listed in the Texas Instruments NexFET family, so dual-sourcing requires a parametric alternative with the same 5x6 mm VSON-CLIP footprint.

Frequently asked questions

What are the key specifications of CSD19532Q5B?

Design engineers need to verify if the part meets their circuit requirements before using it.

Where can I buy CSD19532Q5B in stock?

Sourcing buyers need to quickly find available inventory to fill BOM lines and avoid production delays.

Is CSD19532Q5B obsolete?

Brokers and procurement teams need lifecycle status to assess long-term availability and plan for replacements.

What is the cross reference for CSD19532Q5B?

Maintenance techs and buyers need equivalent parts when the original is unavailable or for cost optimization.

What is the lead time for CSD19532Q5B currently?

Sourcing buyers need lead time information to manage production schedules and avoid shortages.

How does CSD19532Q5B compare to its alternatives?

Design engineers evaluating substitutions need to compare parameters like Rds(on), gate charge, and package.
