Vishay launches AEC-Q200 qualified high power resistor for automotive and industrial applications

May 5, 2025 /SemiMedia/ — Vishay Intertechnology, Inc. has introduced a new AEC-Q200 qualified thick film power resistor in the compact SOT-227B package, designed for mounting on a heatsink. The Vishay MCB ISOA200 offers high pulse handling capability and power dissipation up to 200 W at an 80 °C bottom case temperature. The resistor also features an optional NTC thermistor for internal temperature monitoring and comes with pre-applied Phase Change Thermal Interface Material (PC-TIM) to simplify installation.

Unlike traditional metal-tab designs, the device uses an exposed alumina substrate, reducing both cost and weight. This makes it suitable for a wide range of applications in automotive, industrial, and avionics, military, and space (AMS) sectors, where it can serve as a precharge, discharge, active discharge, or snubber resistor. The resistor can handle high energy pulses up to 140 J for 0.1 seconds and is multi-pulsed tested, making it ideal for applications subject to high and repetitive pulse surges.

In addition to the standard features, the ISOA200 can be integrated with an AEC-Q200 qualified, temperature cycle tested NTC thermistor inside the package, simplifying designs and saving valuable board space. The optional PC-TIM streamlines the installation process during production. The high power and energy dissipation capabilities further reduce the need for additional power components, offering cost savings and design simplification.

The ISOA200 has a resistance range from 10 Ω to 1 MΩ, with tolerances of ± 5 % and ± 10 %, and TCR of ± 100 ppm/K and ± 150 ppm/K. It has a maximum operating voltage of 1500 V, an operating temperature range from -55 °C to +150 °C, and a dielectric strength of 4000 Vrms. The RoHS-compliant device offers a non-inductive design and can include two different resistors.

Samples and production quantities of the new resistor are now available, with lead times of 12 weeks.
