Vishay Intertechnology, Inc. 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 device released today provides higher power dissipation and reliability for multiple and repetitive pulse use. The resistor offers a maximum drift of 2 % after 1000 pulses at 25 °C and a drift less than 5 % after 100 000 pulses, with a turn-on time of 500 ms, turn-off time of 11 s, and pulse energy of 18.9 J. 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 Ω to 10 kΩ — 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.
