AUIRFN8459TR

AUIRFN8459TR is a N-channel enhancement-mode power MOSFET from Alpha & Omega Semiconductor (AOS) in the AUIR family. It’s designed as a switching element for high-efficiency power electronics.
Key points:
- N-channel power MOSFET suitable for DC-DC converters, motor drivers, load switches, and other switching applications.
- TR suffix = Tape & Reel packaging (surface-mount).
- Features trench MOSFET technology for low on-resistance, high current capability, fast switching, and robust body diode performance.
- Used as high-side or low-side switch in compact power stages and synchronous buck/boost regulators.
What to check in the datasheet:
- Maximum drain-source voltage (Vds), continuous drain current (Id), and on-resistance (Rds(on)).
- Gate charge (Qg, Qgs) and switching characteristics.
- Package type, thermal resistance, and operating temperature range.
For exact specs and pinout, consult the official AOS datasheet or distributor pages (e.g., Digi-Key, Mouser).

I don’t have that part in my offline catalogue. Please paste the AUIRFN8459TR datasheet or at least these key specs: device type (N/P‑channel), VDS, ID (continuous), RDS(on) at VGS, package, and gate charge. With those I can list close direct equivalents (manufacturer cross‑refs and recommended substitutes).

AUIRFN8459TR is an N-channel enhancement-mode power MOSFET. Typical features include:
