IRFR9220

IRFR9220 is a N‑channel enhancement‑mode power MOSFET from International Rectifier (now Infineon). It’s used as a fast, efficient switch in power electronics (e.g., DC‑DC converters, motor drives, load switches).
Key points:
- Type: N‑channel MOSFET; conducts when Vgs is above threshold.
- Drive: Typically driven with a gate voltage high enough (commonly around 10 V; some logic‑level variants use 4.5–5 V). Check the exact datasheet for your part.
- Performance: Low drain‑source on-resistance (Rds(on)) under proper gate drive, enabling high current with minimal heat.
- Protection: Includes a body diode; ensure proper gate protection and thermal management.
- Important specs to verify: Vds rating, Id (continuous drain current), Rds(on) at your Vgs, total gate charge (Qg), and package/thermal ratings.
Typical applications: switching regulators, buck/boost converters, motor controllers, and other high‑current switching circuits.
For exact numbers and packaging, consult the specific IRFR9220 datasheet or part variant you’re using.

IRFR9220 features (concise):
- N-channel enhancement-mode power MOSFET
- Voltage rating: around 55 V; rugged for inductive loads
- Very low on-resistance (low Rds(on)) for high efficiency
- High continuous drain current (tens of amps)
- Logic-level gate drive: conducts well at Vgs ≈ 4–10 V
- Fast switching with low gate charge and input capacitance
- Avalanche/short-circuit ruggedness for protection against inductive spikes
- Packages: TO-220AB, D2PAK, DPAK (surface-mount options)
- RoHS compliant; suitable for switching converters, motor drives, and similar applications
Note: exact electrical values depend on the device revision and package; consult the datasheet for precise specifications.

The IRFR9220 is a power MOSFET typically supplied in a TO-220 (TO-220AB) through‑hole package; some manufacturers also offer surface‑mount variants like DPAK/TO‑252. Check the device datasheet for the exact package option.

The IRFR9220 is a 3‑pin N‑channel enhancement‑mode power MOSFET (commonly in a TO‑220/TO‑220FP package).
Pin functions (front view, pins left→right):
1. Gate — control terminal (voltage input that turns the channel on/off).
2. Drain — main current input; also connected to the metal tab/heatsink.
3. Source — current output/return/reference for the load.
Typical use: high‑current, low‑RDS(on) switching and power amplification.
