Product details

Gate charge and switching speed

With a maximum gate charge of 11.6 nC at 4.5 V, the CSD17310Q5A switches fast with a modest gate driver. The 1560 pF input capacitance at 15 V drain is moderate — a standard gate driver will slew the gate in tens of nanoseconds.

Temperature range and environment

The junction temperature range spans -55°C to 150°C, covering automotive under-hood, industrial motor drives, and outdoor telecom equipment. The 150°C maximum junction allows operation in hot environments, but the 3.1 W ambient power limit means the designer must keep the junction below 150°C by managing the thermal resistance from the VSONP pad to ambient.

Lifecycle and sourcing

No end-of-life notice or last-time-buy schedule is in effect. For dual-source planning, TI's NexFET family includes several 30 V N-channel parts in the same VSONP footprint — check the TI cross-reference tool for pin-compatible options with different Rds(on) or current ratings.

Frequently asked questions

What is the equivalent of CSD17310Q5A?

TI's NexFET family includes several 30 V N-channel MOSFETs in the 8-VSONP package with similar Rds(on) and current ratings. The closest pin-compatible alternative would be another TI NexFET part in the same 5x6 VSONP footprint — use the TI cross-reference tool to match Rds(on) and gate charge to your specific switching frequency and load current.

Is CSD17310Q5A compatible with 5V gate drive?

Yes. The drive voltage range is 3 V to 8 V, so a 5 V gate drive signal will turn the MOSFET on. However, the Rds(on) at 5 V will be higher than the 5.1 mOhm figure quoted at 8 V — expect roughly 6 to 7 mOhm at 5 V gate drive. For lowest conduction loss, drive the gate to 8 V if your controller allows it.
