UNISONIC TECHNOLOGIES CO., LTD 20N40 Preliminary Power MOSFET 400V, 23A N-CHANNEL POWER MOSFET DESCRIPTION The UTC 20N40 is an N-channel mode power MOSFET using UTC’s advanced technology to provide customers with planar stripe and DMOS technology. This technology allows a minimum on-state resistance and superior switching performance. It also can withstand high energy pulse in the avalanche and commutation mode. The UTC 20N40 is generally applied in high efficiency switch mode power supplies. FEATURES * RDS(ON)=0.2Ω @ VGS=10V,ID=11.5A * Low Gate Charge (Typical 46nC) * Low CRSS (Typical 25pF) * High Switching Speed SYMBOL ORDERING INFORMATION Ordering Number Lead Free Halogen Free 20N40L-T47-T 20N40G-T47-T Note: Pin Assignment: G: Gate D: Drain S: Source www.unisonic.com.tw Copyright © 2011 Unisonic Technologies Co., Ltd Package TO-247 Pin Assignment 1 2 3 G D S Packing Tube 1 of 6 QW-R502-623.b 20N40 Preliminary Power MOSFET ABSOLUTE MAXIMUM RATINGS (TC=25°C, unless otherwise specified) PARAMETER Drain-Source Voltage Gate-Source Voltage RATINGS 400 ±30 TC=25°C 23 ID Continuous Drain Current TC=100°C 13.8 Pulsed (Note 2) IDM 92 Avalanche Current (Note 2) IAR 23 Single Pulsed (Note 3) EAS 1190 Avalanche Energy Repetitive (Note 2) EAR 23.5 Peak Diode Recovery dv/dt (Note 4) dv/dt 4.5 Power Dissipation (TC=25°C) 235 PD Derate above 25°C 1.8 Junction Temperature TJ +150 Storage Temperature TSTG -55~+150 Notes: 1.
