IRFR9220

IRFR9220 is an N-channel enhancement-mode MOSFET from International Rectifier (now Infineon). It’s used as a fast switching element in power electronics such as DC-DC converters, motor drivers, and LED drivers. It typically offers low on-resistance and higher current capability in common power packages (e.g., TO-220AB, D²PAK). The drain is usually the tab, and a TO-220 pinout is Gate–Drain–Source (G–D–S) with the tab tied to Drain; always verify exact package pinout in the datasheet.
Key things to check in the datasheet:
- Vds (voltage rating) and Id (continuous drain current)
- Rds(on) at your gate drive voltage
- Gate charge (Qgs, Qgd) and switching speeds
- Safe operating area (SOA) and avalanche if relevant
- Vgs rating (usually ±8–20 V)
Use a proper gate drive within Vgs limits and ensure cooling for your intended current.

IRFR9220 is an N-channel MOSFET. Common cross equivalents from other brands include:
- IRF3205
- FQP30N06L
- STP60NF06L
- IRLZ44N
- FQP50N06L
Note: verify packaging (TO-220/D²PAK) and exact specs (Vds, Id, Rds(on), Vgs) via a datasheet cross-reference (Digi‑Key, Mouser) for a precise substitution.

IRFR9220 is an N-channel enhancement-mode power MOSFET. Key features:
- High-voltage switching device (Vds around 200 V class)
- Low on-resistance (Rds(on)) for efficient conduction
- High drain current capability (suitable for significant load currents)
- Fast switching with low input capacitance and reduced gate-drive energy
- Rugged device with reliable avalanche energy rating and robust body diode
- Wide operating temperature range for industrial/automotive use
- RoHS compliant
- Available in common packages (DPAK/TO-252, D²PAK/TO-263, and TO-220 variants)
Note: exact values for Vds, Id, Rds(on), Qg, and package options should be taken from the current datasheet for precise application design.

- Pin count: 3 (three-terminal device)
- Function: Power MOSFET used as a switch. Gate controls current between Drain and Source; Drain is usually tied to the metal tab in its package. Includes an intrinsic body diode from Drain to Source.

Manufacturer: International Rectifier (IR), now part of Infineon Technologies.
What kind of company: A semiconductor company specializing in power electronics (power MOSFETs, IGBTs, diodes, etc.). Infineon is a German multinational semiconductor manufacturer.

IRFR9220 is an N-channel enhancement MOSFET with low Rds(on) and fast switching. Common application areas:
- Switch-mode power supplies and DC–DC converters (buck/boost/buck-boost)
- Motor drive and control (BLDC/DC motors, stepper)
- Inverters for solar systems, UPS, and power electronics
- Automotive power electronics ( DC–DC rails, power management)
- Class-D audio amplifiers and other high-efficiency switching stages
- Power-management/modules in servers, telecom, and consumer electronics
Note: choose where low-voltage/high-current switching with fast turn-on/off is needed.
