Product 1 : Infineon OptiMOS™ power MOSFET in TOLT package
For power semiconductor devices, in order to pursue higher power density, in addition to working hard on processes and materials, exploring new packaging with better thermal performance is also an important technical path.
Infineon has further expanded its OptiMOS power MOSFET product line with the introduction of the TO-Leaded Top-Cooled (TOLT) package. The TOLT package offers the same high-current, low-profile advantages of the TOLL package, but also features top-side cooling for optimal thermal performance. Specifically, top-side cooling exposes the drain electrode to the package surface, allowing 95% of the heat to be dissipated directly to the heat sink. Compared to the TOLL package, the TOLT package improves junction-to-case thermal resistance by 20% and junction-to-ambient thermal resistance by 50% .
The TOLT package, combined with the excellent features of the OptiMOS 5 Power Block MOSFET series, achieves benchmark efficiency and high current handling capability. These power MOSFETs include 80V and 100V models with high current ratings exceeding 300A, making them ideal for high power density designs.

Product 2: Molex Mini-Fit Sigma Connector
While ensuring the electrical performance required by the design, connectors with more compact size and stronger reliability will obviously be more popular with developers.
Molex 's Mini-Fit Sigma connector is one such interconnect solution, featuring a slim-profile design suitable for thin PCBs, a 4.2mm pitch, and support for 14A. The Mini-Fit Sigma connector complies with glow-wire specifications and utilizes the latest Mini-Fit TPA2 contacts, easily mating with standard Mini-Fit Junior receptacles of the appropriate circuit size.
The Mini-Fit Sigma connector's sealing solution prevents the ingress of water, foam, and dust. A rubber cap wraps around the back of the housing, and panel-mounting ears on the plug housing provide secure and stable insertion into the panel. Overall, this connector is ideal for automotive, consumer, appliance, industrial, medical, and telecommunication network applications.
