The FQPF20N60C is a high-performance N-Channel enhancement-mode power MOSFET designed for high-voltage, high-speed switching applications. Housed in a fully isolated TO-220F plastic package, this power transistor is rated for a breakdown voltage of 600V and a continuous drain current of 20A. It utilizes advanced planar stripe DMOS technology to achieve exceptionally low on-state resistance (\(R_{DS(on)}\)), minimized gate charge, and high ruggedness against voltage surges. This makes it an ideal, dependable component for switched-mode power supplies (SMPS), electronic ballast regulators, active power factor correction (PFC), and standard DC-to-AC power inverter circuits.
FQPF20N60C N-Channel Power MOSFET Transistor (TO-220F)
Product Overview
The FQPF20N60C is an advanced N-Channel enhancement-mode power field-effect transistor engineered with proprietary planar stripe and DMOS technology. This specialized semiconductor is custom-tailored to minimize on-state resistance ($R_{DS(on)}$) while providing high avalanche energy strength and swift switching speeds. Packaged in a fully insulated TO-220F molded chassis, it safely isolates the internal substrate from external mounting hardware, eliminating the need for separate insulation sheets in dense circuit layouts.

Key Features
- High Voltage Tolerance: Built to manage high-stress voltage thresholds with a reliable 600V to 650V drain-source breakdown capability.
- Robust Load Handling: Supports up to 20A of continuous drain current under typical baseline operating conditions. [4, 5]
- Ultra-Low On-Resistance: Uses planar stripe geometries to maintain minimal resistance, effectively limiting power losses and thermal buildup.
- Minimized Gate Charge: Low gate charge (typically $Q_g$) ensures faster switching frequencies and less demanding gate-drive power consumption.
- 100% Avalanche Tested: Factored to withstand rugged voltage spikes and reactive energy feedback caused by inductive loads.
- Fully Isolated TO-220F Enclosure: Features a plastic overmolded tab that reduces the risk of accidental electrical shorts directly to external heatsinks.
