FQA70N10
100V N-Channel MOSFET
August 2000
QFETTM
General Description
These N-Channel enhancement mode power field effect
transistors are produced using Fairchild’s proprietary,
planar stripe, DMOS technology.
This advanced technology has been especially tailored to
minimize on-state resistance, provide superior switching
performance, and withstand high energy pulse in the
avalanche and commutation mode. These devices are well
suited for low voltage applications such as audio amplifier,
high efficiency switching DC/DC converters, and DC motor
control.
Features
• 70A, 100V, RDS(on) = 0.023Ω @VGS = 10 V
• Low gate charge ( typical 85 nC)
• Low Crss ( typical 150 pF)
• Fast switching
• 100% avalanche tested
• Improved dv/dt capability
• 175°C maximum junction temperature rating

Notes:
1. Repetitive Rating : Pulse width limited by maximum junction temperature
2. L = 0.4mH, IAS = 70A, VDD = 25V, RG = 25 Ω, Starting TJ = 25°C
3. ISD ≤ 70A, di/dt ≤ 300A/µs, VDD ≤ BVDSS, Starting TJ = 25°C
4. Pulse Test : Pulse width ≤ 300µs, Duty cycle ≤ 2%
5. Essentially independent of operating temperature
