AOK18N65
650V,18A N-Channel MOSFET
General Description
Product Summary
The AOK18N65 is 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 this part 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 impedance 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 impedance 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 rating.
G. L=60mH, IAS=6.3A, VDD=150V, RG=25Ω, Starting TJ=25°C
