State-of-the-art MOSFET handles higher peak currents, delivering a cost-effective, high-performance, and enhanced reliability hot swap solution

The AOTL66935 hot swap MOSFET prevents damage to the system by limiting the high inrush current with low power losses due to the very low on-resistance (R_DS(ON)). These features help deliver increased performance and reliability in harsh application conditions required in latest AI server designs. The AOTL66935 is available in TO-Leadless (TOLL) package, which is 30% smaller footprint compared to TO-263 (D2PAK). AOTL66935 is manufactured in IATF 16949-certified facilities. TOLL package technology is compatible with automated optical inspection (AOI) manufacturing requirements.

“48V hot swap in AI servers requires a MOSFET that excels in high current capability while providing exceptional SOA robustness with high reliability. We designed the AOTL66935 to meet these demands, and the low on-resistance reduces the power losses and can enable less devices in parallel,” said Peter H. Wilson, Sr. Director of MOSFET product line at AOS.

Technical Highlights

Pricing and Availability

The AOTL66935 MOSFET is immediately available in production quantities with a lead time of 14-16 weeks. The unit price in 1,000-piece quantities is $4.2.
