Infineon Technologies has expanded its OptiMOS 6 MOSFET portfolio with the new 135 V and 150 V product families. The devices are designed to meet the requirements of drives and switched-mode power supply (SMPS) applications and complement the recently released OptiMOS 6 120 V MOSFETs. With the extended portfolio, Infineon offers its customers a wide range of alternatives to select the best-fit MOSFETs for various applications. Lower switching losses benefit applications like server SMPS, solar optimizers, high-power USB chargers, and telecom. Improved conduction losses are highly beneficial for motor inverters in e-forklifts and light electric vehicles (LEVs).

Compared to the previous generation (OptiMOS 5 150 V MOSFETs), the new product families offer a reduction in on-state resistance R_DS(on) of up to 50 percent, while the FOM g is reduced by 20 percent. With the very low R_DS(on), their improved switching performance, and excellent EMI behavior, both new families deliver unparalleled efficiency, power density, and reliability. A faster and softer body diode delivers up to 59 percent lower Qrr, less overshoot and ringing.
