Alpha and Omega Semiconductor’s (AOS) AOTL037V60DE2 600-V MOSFET is the first device in production that’s manufactured on the company’s MOS E2 platform. The platform, and its resulting products, were created to meet the needs of high‑power switched‑mode power supplies (SMPS) and inverter systems. It brings higher efficiency, greater power density, lower overall system cost, and high robustness to a wide range of applications, including servers, workstations, telecom rectifiers, solar inverters, motor drives, and industrial power systems.

Suitable for totem-pole PFC, LLC, PSFB, and CrCM H-4/Cyclo Inverter applications, the device is fabricated on AOS’s advanced MOS E2 platform are based on structure that’s optimized for soft‑switching topologies with exceptionally low switching losses. 

It also includes a robust intrinsic body diode, featuring reduced QRR, which reliably handles hard commutation scenarios. One example is reverse recovery of the freewheeling body diode that can occur during abnormal events, such as short‑circuits or startup transients. Other advanced features include strong UIS, inrush current handling, wide SOA capabilities, and resistance to self-turn-on conditions. 

The AOTL037V60DE2, housed in a TOLL package, features a maximum RDS(ON) of 37 mΩ. It’s presently available in production quantities with a lead time of 16 weeks and a unit price in 1,000-piece quantities of $5.58.
