The 3850 pF input capacitance at 10 V drain-source sets the switching energy per cycle; paired with the low Qg, it supports switching frequencies in the tens of kilohertz with modest gate-drive power. ## Package and thermal budgeting The thermal path relies on the copper pad area on the PCB — a 1 oz pour under the package reduces junction-to-ambient thermal resistance. For continuous 20 A operation, the board-level copper area and airflow must be sized to keep the junction below 150 °C.","metaTitle":"RJK0349DSP-01#J0 MOSFET N-CH 30V 20A 8-SOIC, 3.8 mOhm","metaDescription":"Renesas RJK0349DSP-01#J0 N-channel MOSFET, 30 V drain-source, 20 A continuous, 3.8 mOhm Rds(on) at 10 V.
