IRF2804

IRF2804 is a N-channel enhancement-mode power MOSFET from International Rectifier (now Infineon). It is used as a high-current switching device in power electronics (switching power supplies, DC-DC converters, motor drives, inverters). It typically comes in common power packages (e.g., TO-220, D²PAK) with Gate–Drain–Source pins. The device requires a gate drive (around 10 V for low on-resistance; Vth is lower but not sufficient for full enhancement). Ratings (Drains current, Drain–Source voltage, Rds(on)) vary by variant, so consult the exact datasheet for your part. Important design notes: mount on a heatsink for thermal management, respect Vds and Vgs limits (usually up to ±20 V on Vgs), ensure proper gate drive, and use protection elements (snubbers, flyback diodes, TVS) as appropriate. For precise specs and package options, refer to the specific IRF2804 datasheet revision you’re using.

IRF2804 is an N‑channel power MOSFET. Equivalent parts depend on matching Vds, Id, Rds(on) and package. Common substitutes with similar ratings: IRF3205, IRFZ44N, IRLZ44N, FQP30N06L, STP55NF06 (and STP75NF75). For a precise cross, provide the IRF2804 datasheet (Vds, Id, Rds(on), package) and gate drive; I’ll map exact replacements.

IRF2804 features (concise):
- N-channel HEXFET power MOSFET
- Vds: 55 V
- Id (continuous): ≈ 32 A
- Rds(on): ≈ 0.04 Ω (typ) at Vgs = 10 V
- Gate threshold: ~2–4 V; not a logic-level device (drive at ~10 V for low Rds(on))
- Fast switching with low gate charge
- Avalanche-rated for inductive-load switching
- Package options: TO-220AB and D2PAK; Pb-free/RoHS compliant
- Wide operating temp: up to ~150 °C junction
- Applications: SMPS, DC-DC converters, motor control, switching regulators

- Pin count: 3 leads (Gate, Drain, Source) with the metal tab also tied to Drain (TO‑220 package).
- Function: N‑channel enhancement‑mode power MOSFET used as a high‑current switching device in power supplies, motor drivers, etc. Pinout (front view, left to right): Gate, Drain, Source; tab = Drain.

Manufacturer: International Rectifier (IR). It is a semiconductor company specializing in power management devices (power MOSFETs, diodes, IGBTs, etc.). IR is now part of Infineon Technologies (German semiconductor company).
