The FQU1N60B is a 600V N-Channel MOSFET from Fairchild Semiconductor (now ON Semiconductor) designed for high-voltage, high-speed switching applications. It is part of the QFET® MOSFET family and is commonly used in power electronics circuits.

Applications:

• Switch Mode Power Supplies (SMPS)
• Power Factor Correction (PFC) circuits
• Uninterruptible Power Supplies (UPS)
• High-voltage DC-DC converters
• Lighting ballasts

Features:

• High Voltage: 600V Drain-Source Voltage (VDS)
• Low On-Resistance: RDS(on) = 6.5 Ohms (max) at VGS = 10V
• High Switching Speed
• Low Gate Charge

Benefits:

• Improved Efficiency: Low on-resistance minimizes conduction losses.
• Reliable Performance: High voltage rating ensures robust operation.
• Simplified Design: Fast switching speed simplifies circuit design.
• Reduced Heat Dissipation: Lower on-resistance reduces heat generation.
• Enhanced System Reliability: Robust design provides long-term reliability.

Additional Details:

The FQU1N60B is fabricated using planar stripe and DMOS technology. It is available in a TO-251 (I-PAK) package, designed for surface mounting. Key specifications include a continuous drain current (ID) of 1A and a pulsed drain current (IDM) of 3A. The gate-source voltage (VGS) is rated at ±30V. The total gate charge (Qg) is typically 4.5 nC. It is RoHS compliant.
