The company says the devices are designed to meet the requirements of drives and switched-mode power supply (SMPS) applications and complement the recently released launched OptiMOS 6 120 V MOSFETs. With the extended portfolio, Infineon says it 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 optimisers, 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%, while the FOM g is reduced by 20%. With the very low R DS(on), their improved switching performance and excellent EMI behavior, both new families are said to deliver unparalleled efficiency, power density, and reliability. A faster and softer body diode delivers an up to 59% lower Q rr, less overshoot and ringing.
The company says the OptiMOS 6 135 V and 150 V MOSFETs are available in a variety of packages to provide customers with a range of options for best-fit products. This broad package portfolio includes TO-220, D 2PAK 3-pin, D 2PAK 7-pin, TOLL, TOLG, TOLT, SuperSO8 5x6 and PQFN 3.3x3.3.
