AEC-Q200-Qualified 25 W Thick Film Power Resistor

New AEC-Q200-Qualified 25 W Thick Film Power Resistor Saves Space, Lowers Costs in Automotive and Industrial Applications

Vishay Intertechnology introduces a new AEC-Q200-qualified, 25 W thick film power resistor in a compact, surface-mount TO-252 style (DPACK) package.

For automotive, industrial, and military applications, the Vishay Sfernice DTO25 saves space over previous-generation solutions, while providing high power dissipation of at least 3 W on the PCB and a wide range of resistance values.

  • Measures just 8.2 mm by 7.3 mm with a low 2.8 mm profile
  • Supports more than 10 times more energy than competing components in the DPAK package — up to 5 kW+ for a 10-5 second pulse and 10 J for a 0.1 second pulse
  • Provides long-term reliability
  • Allows designers to replace several chip resistors with one device to lower costs, simplify layouts, and reduce the size of their end products

The Key Specifications:

  • Rated power: 25 W at +25 °C case temperature and 3 W on the PCB
  • Resistance range: 0.016 Ω to 700 k Ω
  • Thermal resistance (junction-to-case): 5 °C/W at 25 W and +25 °C
  • Temperature coefficient: ± 150 ppm/°C
  • Dielectric Strength: 1500 Vrms
  • Tolerance: ± 1 %, ± 2 %, ± 5 %, and ± 10 %
  • Operating temperature range: -55 °C to +150 °C

Product Benefits:

  • AEC-Q200 qualified
  • Compact, surface-mount TO-252 style (DPAK) package
  • High power dissipation of at least 3 W on the PCB
  • Wide range of resistance values from 0.016  to 700 k
  • Non-inductive
  • Tinned copper connections specified for operation over a -55 °C to +150 °C temperature range
  • Moisture sensitivity level of 1
  • RoHS compliant and Supports soldering temperatures at +270 °C for 10 seconds

Market Applications:

  • Power supply, load resistor, snubber, power conversion, and pre-charging and discharging in battery management systems for hybrid and electric cars, missile control boards, and UPS


  • Samples and production quantities of the DTO25 are available now, with lead times of eight to 10 weeks for larger orders.
