概述

Description

IRF2804 is a high‑voltage, N‑channel power MOSFET from International Rectifier (now Infineon). It’s used as a switching element in power electronics such as switch‑mode power supplies, motor controllers, and inverters. Key points you’ll find in the datasheet:
- VDS in the hundreds of volts class (roughly 400 V).
- Continuous drain current in the amp-to-tens range.
- RDS(on) designed for efficiency, but typically higher than modern trench MOSFETs.
- Packages include TO‑220 and D²PAK.
Basic usage: source to ground, drain to the load, and gate driven with a suitable positive voltage relative to source (within VGS max, typically up to ±20 V). Include a gate resistor and a protection/diode for inductive loads; provide adequate heatsinking for dissipation.
For precise values (VDS, ID, RDS(on), Qg, thermal data), consult the latest IRF2804 datasheet.

Features

IRF2804 is an N-channel, enhancement-mode power MOSFET. Key features (typical, check datasheet for exact values):
- N-channel power MOSFET with low on-resistance
- High drain current capability with proper heatsinking
- Fast switching, suitable for high-frequency applications
- Robust body diode and avalanche energy rating for inductive loads
- Gate drive compatible with standard gate voltages (check threshold specs)
- Available in multiple packages (TO-220, D2PAK, DPAK, etc.)
- Wide operating temperature range (-55°C to +150°C or similar, depending on variant)
- RoHS compliant and suitable for switching regulators, DC-DC converters, motor drivers, and power amplification
Note: Exact Vds, Id, Rds(on), and package options vary by revision; consult the official datasheet for precise figures.

Package
