FQB5N20L datasheet

Description :

These N-Channel enhancement mode power field effect transistors are produced using Fairchild’s proprietary, planar stripe, DMOS technology. This advanced technology is especially tailored to minimize on-state resistance, provide superior switching performance, and withstand high energy pulse in the avalanche and commutation modes. These devices are well suited for high efficiency switching DC/DC converters, switch mode power supplies, and motor control.


• 4.5A, 200V, RDS(on) = 1.2Ω @VGS = 10 V
• Low gate charge ( typical 4.8 nC)
• Low Crss ( typical 6.0 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
• Low level gate drive requirement allowing direct operation from logic drivers

5LO365R datasheet

Description :

Part Number 5LO365R -> Correct Part Number 5L0365R

The Fairchild Power Switch(FPS) product family is specially designed for an off-line SMPS with minimal external components. The Fairchild Power Switch(FPS) consists of a high voltage power SenseFET and a current mode PWM IC.

Included PWM controller integrates the fixed frequency oscillator, the under voltage lock-out, the leading edge blanking, the optimized gate turn-on/turn-off driver, the thermal shutdown protection, the over voltage protection, and the temperature compensated precision current sources for the loop compensation and the fault protection circuitry.

Compared to a discrete MOSFET and a PWM controller or an RCCsolution, a Fairchild Power Switch(FPS) can reduce the total component count, design size and weight and at the same time increase efficiency, productivity, and system reliability. It has a basic platform well suited for the cost effective design in either a flyback converter or a forward converter.
