MALVERN, PA — Vishay Intertechnology, Inc. (NYSE: VSH) has expanded its D2TO35 series of surface-mount thick film power resistors with the introduction of the D2TO35H. The new Automotive Grade device is AEC-Q200 qualified and capable of delivering higher pulse absorption up to 15 J/0.1 seconds, providing enhanced protection and reliability in demanding applications.
Housed in the TO-263 (D²PAK) package, the D2TO35H offers power dissipation of 35 W at a +25 °C case temperature and boasts a unique design that absorbs 30% more energy than standard D2TO35 resistors. This allows the device to deliver improved stability against short transient pulses, reducing failures in high-stress environments. By requiring fewer components, it also simplifies layouts, conserves board space, and lowers overall solution costs.
Designed for high-performance applications, the resistor operates at temperatures of up to +175 °C and offers a broad resistance range of 1 Ω to 14 kΩ, with precision tolerances down to ± 2%. Its thermal resistance of 4.28 °C/W ensures efficient heat dissipation, while its non-inductive design and solder reflow capability at 270 °C/10 seconds meet the demands of rigorous industrial standards.
The D2TO35H is tailored for critical roles such as active discharge, precharge, or discharge resistors in hybrid electric vehicles (HEVs), electric vehicles (EVs), 48 V board nets, battery management systems (BMS), and on-board chargers. Beyond automotive applications, it is suited for energy monitoring systems, agricultural machinery, industrial motor drives, welding equipment, power tools, and military weapons guidance systems.
This RoHS-compliant resistor exemplifies Vishay’s efforts to deliver durable, efficient solutions for advanced technologies. By enhancing system reliability and offering a cost-effective design, the D2TO35H has the potential to significantly impact the automotive, industrial, and military sectors, meeting stringent requirements while driving innovation.
