Vishay Intertechnology Releases New Top-Side Cooling Mount Thick Film Power Resistor in Compact TO-263 (D²PAK) Package
Vishay Intertechnology introduced the Vishay Sfernice D2TO35S, an Automotive Grade top-side cooling thick film power resistor in the compact TO-263 (D²PAK) surface-mount package. The device delivers 35 W power dissipation at 25 °C and up to nine times greater dissipation than standard PCB-mounted devices when paired with a heatsink, targeting automotive applications where thermal constraints dominate design.
