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.","metaTitle":"CSD25402Q3A NexFET P-Ch MOSFET, 20V, 76A, 8.9mOhm","metaDescription":"Texas Instruments CSD25402Q3A NexFET P-Channel MOSFET, 20V Vdss, 76A Id, 8.9mOhm Rds(on) at 4.5V.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/texas-instruments/CSD25402Q3A","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/texas-instruments/CSD25402Q3A when reusing this data.
