IRF730 5.5A 400V N-Channel MOSFET

The IRF730 5.5A 400V N-Channel MOSFET is a high-voltage switching transistor engineered for efficient power management in demanding electronic applications. It supports continuous drain currents up to 5.5 A and a drain‑source voltage rating of 400 V, providing reliable performance in circuits that require elevated voltage tolerance and stable operation.

• 5.5A continuous drain current for dependable operation under moderate loads.
• 400V drain‑source voltage rating suited for high-voltage power designs.
• Low gate charge to enable faster switching and reduced energy loss during transitions.
• RDS(on) of approximately 1.5 ohms to minimize conduction losses where applicable.
• Compact TO‑220 package for straightforward mounting and effective heat dissipation in constrained spaces.

Designed to balance voltage endurance, current handling and switching efficiency, the IRF730 leverages semiconductor design choices that reduce gate capacitance and lower thermal resistance relative to less optimized packages. These characteristics contribute to quicker switching cycles, reduced heat generation during operation and improved overall efficiency when integrated into power conversion, motor drive, or switching regulator circuits.

Well suited for both hobbyist and professional projects, the IRF730 offers a versatile option when mid‑range power transistor specifications are required and when reliable high‑voltage switching is a priority.
