Product details

6.2 mOhm at 15 A, 10 V drive — the conduction loss floor

The Texas Instruments CSD17552Q5A is a NexFET series N-channel MOSFET in an 8-PowerTDFN package, rated for 30 V drain-to-source.

12 nC gate charge — logic-level drive ready

Gate charge is 12 nC max at 4.5 V, which means a 5 V logic-level gate driver can switch this FET without a separate gate-drive boost stage. The drive voltage range of 4.5 V to 10 V for achieving the rated Rds(on) covers both 5 V logic and 10 V gate-drive rails. Input capacitance is 2050 pF at 15 V drain bias — modest enough that the gate driver's peak current capability sets the switching speed, not the FET's input charge.

The 3 W power dissipation at ambient (Ta) is the limit with minimal copper; the actual thermal capability depends on the PCB's copper area under the exposed pad.

It is ROHS3 compliant, with no lead or restricted substances above the threshold.

Frequently asked questions

Is CSD17552Q5A RoHS and lead-free compliant?

Yes, the CSD17552Q5A is listed as ROHS3 compliant, meaning it meets the EU RoHS directive with no restricted substances above the threshold.

What is the Rds(on) of CSD17552Q5A?

The maximum on-resistance is 6.2 mOhm at 15 A drain current with 10 V gate drive. This is the conduction loss figure to use for thermal budgeting at the operating current.

What is the gate charge specification for CSD17552Q5A?

Maximum gate charge is 12 nC at 4.5 V gate voltage. This low Qg allows efficient switching from a 5 V logic-level gate driver without additional gate-drive circuitry.
