IRF830 MOSFET Transistor TO-220 (SH) Code: 56300894

The IRF830 is a popular, high-voltage, N-channel power MOSFET widely used in switching voltage regulators, DC-DC converters, and motor control circuits. It features a maximum drain-to-source voltage of 500 V, a continuous drain current of 4.5 A, and an on-state resistance of 1.5 Ω.

Pinout Configuration

The IRF830 comes in a standard 3-pin TO-220 package, making it easy to mount onto a heatsink for improved heat dissipation.

1. Gate (Pin 1):Controls the biasing of the MOSFET (Threshold voltage is typically 4 V to 10 V).
2. Drain (Pin 2):The input terminal where the current flows in.
3. Source (Pin 3):The output terminal where the current flows out.
