AONR66820 and AONS66811 are Power MOSFETs in DFN3.3x3.3 and DFN 5x6 package, respectively. AONR66820 is perfectly suited for isolated DC-DC converters used in telecom applications. AONS66811 is appropriate for synchronous rectification and provides improved reverse recovery charge and reduced voltage overshoot, which provides higher efficiency and more robustness to the power supply.

The AOTL66810 (80V) in TOLL package has approximately 25% smaller footprint than a standard wire-bonded TO-263 (D2PAK) package. This new device offers a higher power density compared to existing solutions. It is ideally suited for industrial BLDC motor applications and battery management to reduce the number of MOSFETs in parallel. The AOTL66810 has a 1.25mOhms max at 10Vgs with a maximum drain current of 420A at 25°C. The pulsed current at 1700A, is limited by the maximum junction temperature of 175°C.

“With the significant performance improvement with clip technology in a robust TOLL package enables higher current density and higher current capability. The AOTL66810 simplifies new designs to enable savings in overall system cost due to a reduced number of devices in parallel. AOS’s TOLL package is best suited for high power applications,” said Peter H. Wilson, Director of LV/MV MOSFETs at AOS.
