FDA50N50 selection and design context
FDA50N50 is cataloged as a N-Channel MOSFET in the UniFET II family. Its recorded function is 500 V N-channel power MOSFET for high-power switching and power-conversion applications. Selection should be based on the complete electrical limits, package drawing and ordering suffix rather than the abbreviated family code.
- Drain-Source Voltage: 500 V. Check rail compatibility, tolerance and sequencing under worst-case conditions.
- Continuous Drain Current: 48 A at 25°C case. Check steady-state, transient and thermal margin in the intended operating mode.
- RDS(on): 105 mΩ maximum at 10 V gate drive. Confirm the value and its datasheet test conditions for the exact ordering suffix.
- Technology: UniFET II MOSFET. Confirm the value and its datasheet test conditions for the exact ordering suffix.
Application and qualification considerations
When evaluating this switching device, confirm voltage and current margin, gate-drive conditions, on-state loss, switching energy, thermal impedance and safe operating area. For a new design, review power-up behavior, interface timing, absolute maximum ratings, thermal limits and any external-component requirements in the latest manufacturer documentation. Existing-board replacement work should additionally confirm pinout, footprint, firmware assumptions and qualification grade.
Procurement checks for FDA50N50
The recorded package is TO-3PN, the temperature range is -55°C to +150°C junction, and the lifecycle status is Production as of 2026-07-20. Before ordering, confirm the exact MPN on the label, packing format, quantity, date-code requirements, traceability documents and current factory status.
FDA50N50 FAQ
What distinguishes FDA50N50 within the UniFET II family?
