PMEG4005CEAX

PMEG4005CEAX is a N-channel enhancement-mode power MOSFET from the PMEG family (Nexperia). It is a surface‑mount switching transistor intended for fast, efficient power switching in low-voltage electronics.
Key points:
- Applications: DC-DC converters, load switches, motor drivers, PWM power switching.
- Package: small SMT package suitable for compact boards.
- Ratings (check datasheet for exact numbers): drain-source voltage around 40 V, current capability in the amps, and a finite on-resistance (Rds(on)) suitable for efficient conduction.
- Drive: logic‑level or near‑logic gate drive commonly used in switching circuits.
- Other: features such as fast switching, ruggedness, and typical gate thresholds suitable for standard control voltages.
For precise electrical specs (Vds, Id, Rds(on), Vgs(th), Qg, package type), consult the latest PMEG4005CEAX datasheet.

Pin count: 2 pins. Function: Schottky barrier rectifier diode (PMEG4005CEAX) used for rectification in power supplies. Package: SMA/DO-214AC. Pin 1 = anode, Pin 2 = cathode (cathode indicated by the stripe).

- Manufacturer: Nexperia
- What kind of company: A global semiconductor company that specializes in discrete components (power MOSFETs, diodes, etc.), as well as logic and other solutions. It originated from Philips/NXP and is now an independent company headquartered in the Netherlands.
