概述

Description

FCH040N65S3-F155 is a high-voltage N-channel power MOSFET (Fairchild/ON Semiconductor). It is designed for switching applications in offline power supplies, PFC stages, DC-DC converters, and motor drives.
Key points:
- Voltage class: around 650 V (Vds rating)
- On-resistance: low (tens of milliohms, ~0.04 Ω typical), enabling efficient conduction
- Package: S3 (power package; check datasheet for exact pinout)
- Gate drive: typically driven with ~10 V for lowest Rds(on); Vgs(th) usually a few volts
- -F155: date/lot code; see datasheet for exact electricals and thermal specs (Id, Qgs, Qgd, switching speed, Rth(j-a))
Note: Always consult the latest datasheet for exact specs and safe operating area before design.

Features

Key features of FCH040N65S3-F155:
- 650 V N-channel enhancement-mode MOSFET
- Low on-resistance: ~40 mΩ (typ) at VGS = 10 V
- High current capability and robust switching for offline power/converter use
- Avalanche-rated with rugged body diode for inductive load switching
- Fast switching characteristics with relatively low gate charge
- Wide-temperature operation (typical performance specified from -55°C to +150°C)
- Package: S3 (TO-263/D²PAK style), RoHS-compliant and lead-free
- Suitable for switched-mode power supplies, PFC, DC-DC converters, motor drives
Note: For exact parameters (Id rating, packaging options, and thermal limits) refer to the manufacturer’s datasheet.

Package

D²PAK (TO-263) surface-mount package.

Pinout

Pin count: 3 electrical pins plus a heatsink/mounting tab (the tab is electrically the drain).
Pin functions (standard MOSFET pinout):
- Pin 1: Gate — control input.
- Pin 2: Drain — main current input/output (also connected to the metal tab).
- Pin 3: Source — return/ground for the channel.
For exact package pin numbering and mechanical details, confirm with the device datasheet.
