概述

Description

DMN65D8LQ-7 is a N-channel power MOSFET (enhancement mode) in the DMN65D8LQ-7 family from Nexperia/NXP. It’s designed for high‑voltage switching applications such as DC‑DC converters, motor drivers, and load switches.
Key points:
- Voltage/role: High‑voltage N‑channel MOSFET for switching power stages.
- Rating hint: The “65” suggests about 65 V drain–source rating.
- Package: LQ‑type surface-mount package; suitable for compact, thermally managed layouts.
- Performance: Aims for low on‑resistance and fast switching; check the datasheet for exact Id, Rds(on), gate threshold, and thermal data.
- Variant note: The “-7” suffix identifies a particular revision/grade; verify exact electrical specs and footprint in the datasheet.
For precise numbers (Vds, Id, Rds(on) at a given Vgs, thermal resistance, and package footprint), consult the official DMN65D8LQ‑7 datasheet on Nexperia’s site or authorized distributors.

Features

DMN65D8LQ-7 is a compact N-channel enhancement MOSFET. Key features (typical for this family):
- VDS: 65 V
- RDS(on): very low milliohms (typical around 7–8 mΩ at VGS ≈ 4.5 V; lower with higher gate drive)
- High current capability (tens of amps, depends on package and mounting)
- Trench-gate technology for fast switching and low gate charge
- Avalanche ruggedness and good dv/dt tolerance for switching power applications
- Gate drive suitable for logic-level operation (VGS(th) ~1–3 V; designed for efficient switching)
- RoHS-compliant, lead-free; suitable for surface-mount use
- Typical applications: synchronous buck DC-DC converters, power switches in motor drives, and other high-efficiency switching power supplies
Note: exact parameters vary by lot and package. For precise numbers, consult the specific datasheet and package variant.

Package

It’s an 8‑pin QFN (leadless) package.

Pinout

Pin count: 3.
Function: N‑channel enhancement‑mode MOSFET (three terminals: Gate, Drain, Source) used for low‑voltage switching, load control and power switching (control input on Gate, current path between Drain and Source).

Manufacturer

The DMN65D8LQ-7 is made by Diodes Incorporated. Diodes Incorporated is a global semiconductor company that designs and manufactures discrete semiconductors, analog and mixed-signal ICs (including MOSFETs, diodes, rectifiers and power-management devices).

Equivalent

Common equivalents are any logic‑level N‑channel MOSFET in SOT‑23 with VDS ≥ the DMN65D8LQ‑7 rating and similar RDS(on) and VGS(th). Typical drop‑in substitutes: 2N7002, BSS138 and Si2302 (check pinout, RDS(on), VDS and package). Always verify electrical specs and footprint before replacing.
