概述

Description

STD45N10F7 is an STMicroelectronics N-channel enhancement-mode power MOSFET used for high-current, high-voltage switching. It targets the 100 V class with roughly 45 A continuous current, and features low on-resistance (in the tens of milliohms range) for efficient switching. The gate threshold is a few volts, with good drive characteristics at typical gate voltages used in power electronics. It’s commonly used in applications like DC-DC converters, motor drivers, and power inverters, and comes in standard power-MOSFET packages (surface-mount or through-hole variants). For exact ratings, package type, thermal data, safe-operating-area, and pinout, consult the official datasheet.

Features

STD45N10F7 is STMicroelectronics’ 450 V N-channel MOSFET (STD series). Key features include:
- N-channel enhancement-mode power MOSFET
- VDS = 450 V; ID = 10 A (continuous)
- RDS(on) typical around 0.9 Ω at VGS = 10 V (datasheet specifies exact limits)
- Gate threshold roughly 2–4 V
- Avalanche-energy rugged for switching applications
- Fast switching capability with moderate gate charge
- Wide operating temperature (up to ~150°C)
- RoHS compliant
- Available in standard package variants (e.g., surface-mount or through-hole with F7 suffix variants)
Note: exact RDS(on), max ratings, and available packages should be confirmed in the official datasheet for the specific lot and packaging.

Pinout

Pin count: 3 electrical pins (plus a metal mounting tab).
Functions (typical pin assignment, front view left-to-right):
- Pin 1: Gate — voltage input that controls the MOSFET channel.
- Pin 2: Drain — power input/output; also connected to the metal tab for heatsinking.
- Pin 3: Source — return/reference for the load (usually connected to ground in low-side switch).
(Std45N10F7 is an N-channel power MOSFET; verify package-specific pin ordering in the datasheet for your exact package.)

Manufacturer

Manufacturer: STMicroelectronics (ST).
What kind of company: STMicroelectronics is a global semiconductor company that designs, develops and manufactures integrated circuits and discrete semiconductor devices (including power MOSFETs, microcontrollers, analog ICs, sensors and related components).

Application
