Input capacitance Ciss is 1440 pF at 15 V Vds; that figure sets the driver's dynamic power budget and the gate-drive loop's resonant frequency. ## Package and thermal path The 8-VSON-CLIP package (3.3x3.3 mm) uses a copper clip over the die, reducing package resistance and pulling heat into the board's copper plane through the exposed pad. Maximum power dissipation at 25 °C ambient is 2.8 W; in practice the board's copper area and airflow set the real thermal limit — the 60 A case rating assumes a heatsink or large copper pour. ## Lifecycle and compliance It is ROHS3 compliant.","metaTitle":"CSD17309Q3 NexFET N-Ch MOSFET, 30V, 5.4mOhm, 8-VSON","metaDescription":"Texas Instruments CSD17309Q3 N-channel NexFET MOSFET, 30V Vdss, 5.4mOhm Rds(on) at 18A.
