M3966m Mosfet Verified Jun 2026

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.

Most commonly found in the PDFN5x6-8L or TO-252 packages, optimized for surface mount technology and heat dissipation. Why "Verified" Matters: Avoiding Counterfeits

The is a high-efficiency, 30V N-channel fast-switching power MOSFET manufactured by uPI Semiconductor (UBIQ) . It is heavily utilized as a critical surface-mount component in modern computer electronics, particularly within the power delivery infrastructure of Asus laptops and motherboards. When repairing hardware or designing high-density power modules, ensuring your component is a verified, genuine M3966M is necessary to prevent terminal circuit failure. Core Specifications Overview m3966m mosfet verified

The M3966M family is manufactured using an optimized trench field-effect transistor technology. This design minimizes gate charge and on-state resistance (

The marking “M3966M” seen on small QFN/PDFN MOSFETs used in laptop and GPU VRAM power circuits most commonly corresponds to the UBIQ (or OEM-labeled) QM3966 family (examples: QM3966M3, QM3966M6). These are N‑channel power MOSFETs in compact packages (PDFN/QFN variants) rated for low voltage (≈30 V) and designed for synchronous buck switching in high-current, space-constrained applications (VRAM/GPU VR rails, CPU/GPU power stages). Note: Pins 5, 6, 7, and 8 are

: Compact DFN3x3 or QFN-8 for space-constrained designs.
