Vishay Intertechnology, Inc. (NYSE: VSH) today introduced a new
AEC-Q200-qualified, 25 W thick film power resistor in a compact
surface-mount TO-252 style (DPAK) package. For automotive,
industrial, and military applications, the Vishay Sfernice DTO25
saves space compared with previous-generation solutions while
providing high power dissipation of at least 3 W on the PCB and a
wide range of resistance values.
The DTO25 is non-inductive and provides a resistance range from
0.016 Ω to 700 kΩ. Offering a compact 8.2 mm by 7.3 mm footprint
with a low 2.8 mm profile, the thick film resistor can support 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.
The device released today provides long-term reliability for
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. In these
applications it allows designers to replace several chip resistors
with one device to lower costs, simplify layouts, and reduce the
size of their end products.
Thermal resistance for the DTO25 at 25 W and +25 °C is
5 °C/W junction-to-case. The resistor features a standard
temperature coefficient of ± 150 ppm/°C with standard
tolerances of ± 1 % to ± 10 %. Connections for the new resistor are
tinned copper, and they are specified for operation over a
-55 °C to +150 °C temperature range. The device is
RoHS-compliant, offers a moisture sensitivity level of 1, and
supports soldering temperatures at +270 °C for 10 seconds.
Samples and production quantities of the DTO25 are available
now, with lead times of eight to 10 weeks for larger orders.
