Vishay Intertechnology, Inc. has introduced a new automotive grade surface-mount thick film power resistor in the TO-263 (D2PAK) package. For automotive applications, the AEC-Q200 qualified Vishay Sfernice D2TO35M combines multi-pulse capabilities with high power dissipation of 35 W at 25° C.
Compared to standard devices in the TO-263 (D2PAK) package, the new device provides higher power dissipation and reliability for multiple and repetitive pulse use. The resistor offers a maximum drift of 2% after

The device withstands 1000 cycles of rapid change of temperature (RCT) testing and offers a load life of 1000 hours.
Offering a non-inductive design, the D2TO35M features a resistance range from 10 W to 10 kW — with tolerances of ± 2%, ± 5%, and ± 10% — thermal resistance of 4.28° C/W, TCR of 150 ± ppm/° C, and a wide operating temperature range from -55° C to 175° C. The RoHS-compliant device is solder reflow secure at 270° C/10 s.
Samples and production quantities of the D2TO35M are available now with standard lead time.
