AOT7N70/AOTF7N70
700V, 7A N-Channel MOSFET
General Description
The AOT7N70 & AOTF7N70 have been fabricated using
an advanced high voltage MOSFET process that is
designed to deliver high levels of performance and
robustness in popular AC-DC applications.
By providing low RDS(on), Ciss and Crss along with guaranteed avalanche capability these parts can be
adopted quickly into new and existing offline power supply
designs.

A. The value of R θJA is measured with the device in a still air environment with T A =25°C.
B. The power dissipation PD is based on TJ(MAX)=150°C, using junction-to-case thermal resistance, and is more useful in setting the upper
dissipation limit for cases where additional heatsinking is used.
C. Repetitive rating, pulse width limited by junction temperature TJ(MAX)=150°C, Ratings are based on low frequency and duty cycles to keep initial TJ
=25°C.
D. The R θJA is the sum of the thermal impedence from junction to case R θJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300 µs pulses, duty cycle 0.5% max.
F. These curves are based on the junction-to-case thermal impedence which is measured with the device mounted to a large heatsink, assuming a
maximum junction temperature of TJ(MAX)=150°C. The SOA curve provides a single pulse ratin g.
G. L=30mH, IAS=5A, VDD=150V, RG=25Ω, Starting TJ=25°C
