Features

The IRFP460A is a robust N-channel MOSFET with the following key features:
- Voltage Rating: 500V, suitable for high-voltage applications.
- Current Handling: Up to 20A continuous drain current.
- Low On-Resistance: 0.27Ω (max) for reduced conduction losses.
- Fast Switching: Optimized for efficiency in switching circuits.
- High Power Dissipation: 280W (with proper heat sinking).
- Avalanche Energy Rated: Enhances reliability in inductive loads.
- TO-247 Package: Ensures good thermal performance.
Commonly used in power supplies, inverters, and motor drives.

Pinout

The IRFP460A is a TO-247AC packaged N-channel MOSFET with 3 pins:
1. Gate (G) – Controls the switching operation (typically driven by 4–10V).
2. Drain (D) – Handles high current/voltage (rated for 500V, 20A).
3. Source (S) – Common return path, connected to ground.
Key Features:
- 500V drain-source voltage (VDS)
- 20A continuous drain current (ID)
- Low on-resistance (RDS(on) ~ 0.27Ω)
- Fast switching for power applications (e.g., inverters, SMPS).
Used in high-power switching circuits, motor drives, and amplifiers. Requires proper heat sinking due to high power dissipation.

Application

The IRFP460A, a 500V/20A N-channel MOSFET, is widely used in:
1. Power Supplies – High-voltage switch-mode power supplies (SMPS) and inverters.
2. Motor Drives – Industrial and automotive motor control systems.
3. Audio Amplifiers – High-power Class-D amplifiers.
4. Induction Heating – Efficient energy conversion in heating systems.
5. Renewable Energy – Solar inverters and wind power converters.
6. Welding Equipment – High-current switching applications.
Its high voltage tolerance, low on-resistance, and robust design make it ideal for demanding power electronics.

Package

The IRFP460A is a power MOSFET housed in a TO-247AC package. This package type features a robust, three-lead design with a metal tab for efficient heat dissipation, making it suitable for high-power applications. The TO-247AC is larger than the TO-220, offering better thermal performance and higher current-handling capability.
