Description

IRFP240 is a high-voltage N-channel power MOSFET (from the IR/Infineon family). Key points:
- Ratings: Vds 200 V; Id continuous about 14 A; Rds(on) typically around 0.28 Ω (at Vgs = 10 V, Tc ≈ 25°C).
- Gate drive: Not a logic-level device; needs ~10 V on the gate for low Rds(on).
- Package: Commonly TO-220 (through-hole), with RoHS variants (e.g., PBF).
- Use cases: Switching regulators, DC-DC converters, motor drivers, high-voltage switching circuits.
- Pros/cons: Robust HV device with simple drive; higher Rds(on) and gate charge than many modern HV MOSFETs, so heat sinking and proper drive are important.
- Notes: Widely available, especially in older or hobbyist designs; verify exact part variant and datasheet for thermal limits and conditions.
In short: a rugged 200 V N-channel MOSFET suitable for high-voltage switching, but newer parts can offer lower on-resistance and better efficiency.

Features

Concise features of IRFP240:
- N-channel, enhancement-mode power MOSFET
- VDS = 200 V; ID (continuous) ~14 A
- RDS(on) ≈ 0.18–0.25 Ω at VGS = 10 V (typ)
- Gate threshold ~2–4 V; VGS max ±20 V
- Fast switching suitable for PWM and switching supplies
- Avalanche-rated / rugged for energy absorption
- TO-220AB package (through-hole)
- Used for high-voltage switching and linear power applications
- Manufacturer: International Rectifier (now part of Infineon)

Package

The IRFP240 is an N-channel power MOSFET typically supplied in a TO‑247 three‑lead through‑hole power package (large plastic body with a metal mounting tab, usually tied to the drain).

Pinout

IRFP240 is a 3-pin N-channel power MOSFET. Typical pinout (front view, leads downward):
1. Gate — control terminal (voltage input to turn MOSFET on/off)
2. Drain — high-voltage terminal (connected to the metal tab/heatsink)
3. Source — return/low-side terminal (current flows out here when on)
Function: it’s an N-channel enhancement-mode MOSFET used for switching and linear amplification of high-voltage/high-current signals.

Manufacturer

The IRFP240 is a power N-channel MOSFET originally manufactured by International Rectifier (IR), a U.S. semiconductor company specializing in power-management devices (power MOSFETs, IGBTs, drivers, etc.). International Rectifier was acquired by Infineon Technologies in 2015; Infineon is a German semiconductor manufacturer focused on power semiconductors, automotive, industrial, and security solutions.

Application

IRFP240 is a 200 V, ~14 A N-channel power MOSFET used for high‑voltage switching. Common applications:
- Switch‑mode/offline SMPS and DC–DC converters
- Motor/actuator drivers (DC motors, steppers)
- Inverters and H‑bridge circuits
- Class D audio power amplifiers
- Solar/battery power electronics and other 200 V range switching circuits

Equivalent

Do you mean direct drop‑in replacements (same pinout/package and specs) or modern substitutes? Also specify key parameters you need matched (VDS, ID, RDS(on), package) and the application (audio, switching). I’ll list equivalent parts once you confirm.
