250V,5A N-Channel MOSFET
General Description
Product Summary
The AON7458 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 device can be adopted
quickly into new and existing offline power supply
designs.This device is ideal for boost converters and
synchronous rectifiers for consumer, telecom, industrial
power supplies and LED backlighting.

A. The value of RθJA is measured with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA =25°C. The
Power Dissipation PDSM is based on RθJA t ≤ 10s value and the maximum allowed junction temperature of 150°C. The value in any given
application depends on the user's specific board design.
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 RθJA is the sum of the thermal impedance from junction to case RθJC and case to ambient.
E. The static characteristics in Figures 1 to 6 are obtained using <300µs 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.These tests are performed with the device mounted on 1 in2 FR-4 board with 2oz. Copper, in a still air environment with TA=25°C.
H. L=60mH, IAS=2.1A, VDD=150V, RG=10Ω, Starting TJ=25°C.
