Product details

Gate charge and drive voltage range

The drive voltage range spans 4.5 V to 10 V, allowing flexibility in the gate supply rail. 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.

Frequently asked questions

What is the closest pin-compatible alternative to RJK0349DSP-01#J0?

For dual-sourcing, evaluate other 30 V N-channel MOSFETs in the 8-SOIC package with similar Rds(on) and gate charge — the 3.8 mOhm at 10 V and 25 nC Qg are the key matching parameters.

What package does RJK0349DSP-01#J0 use?

The device is supplied in an 8-SOIC package (0.154-inch body width, 3.90 mm width) for surface-mount assembly.
