Description

AO4425 is a high-performance N-channel enhancement-mode power MOSFET from Alpha & Omega Semiconductor. It’s used as a switching device in power electronics, such as DC-DC converters, motor drivers, and load switches. Key features typically include low on-resistance (Rds(on)) for high efficiency, good current handling, and fast switching suitable for high-frequency operation. The device is offered in common surface-mount packages (e.g., D2PAK/TO-252 or SO-8) and comes in variants rated for different maximum drain‑source voltages (Vds) and currents. Because parameters vary by package and grade, always consult the AO4425 datasheet for exact specs (Vds, Id, Rds(on), switching characteristics) for the specific part you’re using.

Features

AO4425 is an N-channel enhancement-mode power MOSFET. Key features:
- VDS: 55 V
- Low RDS(on): typically in the single-digit milliohm range (depends on package)
- High drain current capability (depends on package, commonly 8–15 A)
- Trench MOSFET technology for low gate charge and high density
- Fast switching with low gate drive requirements (VGS 4.5–10 V)
- Rugged avalanche energy rating for inductive loads
- Good dv/dt immunity
- RoHS compliant; available in surface-mount packages (e.g., DPAK/TO-252, D2PAK/TO-263)
- Ideal for DC-DC converters, switching regulators, and other high-speed switching applications
Note: exact numbers (RDS(on), Id) vary by package and operating conditions; consult the datasheet for precise specifications.

Package

AO4425 is a power MOSFET in surface-mount packages. Common options are DPAK (TO-252) and D2PAK (TO-263); always check the specific datasheet or supplier listing for the exact package variant.

Pinout

- Pin count: 3 pins (G, D, S); the drain is typically connected to the package tab in many packages.
- Function: N-channel enhancement-mode power MOSFET used as a high-/low-side switch in switching regulators and power circuits.

Manufacturer

Manufacturer: Alpha & Omega Semiconductor (AOS).
What kind of company: A global semiconductor company that designs and manufactures power semiconductors (e.g., MOSFETs, IGBTs, power ICs) for power-management applications in automotive, consumer, and industrial electronics.

Application

AO4425 is an N-channel power MOSFET. Typical application areas:
- High-efficiency switching regulators (buck/boost, synchronous rectification)
- Power switches in voltage regulators and PMICs
- Motor control (DC motors, BLDC) and gate-drive circuits
- Automotive and industrial power electronics (DC-DC converters, load switching)
- Solar/renewable energy electronics (charge controllers, inverters)
- General power-switching in portable devices and adapters
Low on-resistance and fast switching make it suitable for compact, high-efficiency power paths.
