Product details

P-Channel power switch for tight spaces

The Texas Instruments CSD25402Q3A is a NexFET™ P-Channel MOSFET in an 8-VSONP (3x3.15) package — a compact footprint for load switching and battery protection in portable or space-constrained gear.

Conduction loss and drive voltage

Rds(on) is 8.9 mOhm maximum at Vgs = 4.5 V and Id = 10 A — that is the number to use for worst-case conduction loss in a 5 V or 3.3 V gate-drive rail. The part is specified for drive voltages as low as 1.8 V (minimum Rds(on) condition) and as high as 4.5 V (maximum Rds(on) condition), so it works with logic-level gate signals from a microcontroller or a dedicated gate driver. Gate charge is 9.7 nC at Vgs = 4.5 V, and input capacitance is 1790 pF at Vds = 10 V.

Temperature range and thermal budget

Maximum power dissipation is 2.8 W at ambient (Ta) and 69 W at case (Tc) — the real thermal limit depends on the PCB copper area under the 8-VSONP pad.

Frequently asked questions

CSD25402Q3A vs CSD25404Q3A: what are the differences?

The CSD25404Q3A is a higher-current sibling in the same NexFET P-Channel family, but the CSD25402Q3A is the 76 A rated version with 8.9 mOhm Rds(on). The CSD25404Q3A typically offers a lower Rds(on) for even higher load currents. Both share the same 8-VSONP footprint and pinout, so they are drop-in alternatives for designs that need more or less conduction loss margin.
