概述

Description

FDS6670AS is a dual N‑channel enhancement MOSFET pair from Fairchild/On Semiconductor used for compact, high‑efficiency power switching. In a single package it provides two logic‑level N‑channel FETs suitable for synchronous buck converters, load switching, and motor control.
Key points
- Packaged as a dual MOSFET in a small SMD footprint (typically 8-pin style such as SO-8/DFN variants; check the exact package from the datasheet).
- Designed for low on‑resistance and low gate charge to maximize efficiency at modest gate drives.
- Suitable for high-speed switching with common body diodes for reverse current protection.
- Gate threshold and drive requirements are compatible with logic-level controllers.
Typical use cases
- DC‑DC converters (synchronous rectification)
- Power switches and load switches in portable devices
- Small motor drives and other switching applications
For exact electrical ratings (Vds, Id, Rds(on)), package options, and thermal data, consult the official datasheet from On Semiconductor/Fairchild.

Features

Here are the key features of FDS6670AS:
- Dual N-channel enhancement-mode MOSFETs in one package
- Designed for high-efficiency power switching (suitable for synchronous buck and similar apps)
- Low on-resistance (low conduction losses)
- Logic-level gate drive (works well with standard gate voltages)
- Fast switching with low gate charge
- High current capability per FET
- Built-in body diodes with good avalanche ruggedness
- Advanced MOSFET structure (e.g., trench) for performance
- Compact package (RoHS-compliant, e.g., SO-8 or similar) for tight PCB layouts
For exact electrical ratings (Vds, Id, Rds(on), gate charge) and packaging details, please consult the official datasheet.

Package

The FDS6670AS is a dual N‑channel MOSFET supplied in an 8‑lead SOIC/SOP surface‑mount package (SO‑8).

Pinout

Pin count: 8 pins (SOIC/SO-8 style package).
Function: dual N‑channel enhancement‑mode power MOSFET — two discrete N‑channel MOSFETs in one package for low RDS(on) power switching (gates, drains and sources for each transistor). Typical uses: synchronous rectification, load switching, DC‑DC converters and other high‑speed low‑loss switching applications.

Manufacturer

The FDS6670AS is a product of Fairchild Semiconductor (now part of ON Semiconductor after Fairchild’s 2016 acquisition). Fairchild was a semiconductor company that designed and manufactured discrete and integrated semiconductor devices—particularly power MOSFETs, analog ICs and power-management components.

Application

FDS6670AS is a dual N-channel MOSFET used in power-management circuits. Applications: synchronous buck/boost DC-DC converters, load-switches and high-side/low-side switch circuits, LED driver power stages, motor-control circuits, and battery-powered portable equipment and automotive electronics.
