M3966m Mosfet Verified

  1. A house number (custom marking for a specific OEM like a power supply or car audio manufacturer).
  2. A proprietary part from a Chinese or Taiwanese brand (e.g., MikroElektronika, Master Instrument, or a generic brand).
  3. A misread marking (common with SOT-23 packages where "M3966" might be a date/batch code).

Type:

Engineers typically verify the M3966M for applications requiring stable voltage regulation and high-speed switching. N-Channel MOSFET. Voltage Rating ( VDScap V sub cap D cap S end-sub ): Approximately 30V . Continuous Drain Current ( IDcap I sub cap D ): Up to 2.5A under standard operating conditions. On-Resistance (

Note: Pins 5, 6, 7, and 8 are often tied internally to the large thermal pad on the underside of the chip, providing better heat dissipation. m3966m mosfet verified
