The SD Series of Bourns Mini Breakers is the first AEC-Q200 tested and approved as automotive grade standard components. The new Model SD Series feature high current and low resistance (less than 4 mΩ) over temperature protection components.

These devices, offered in either a surface mount (SD) or axial leaded / weldable (AD) package. The SD series also offers the option for the TCO device to be either non-automatically resettable (self-hold function) or automatically resettable (non self-hold function).

These devices feature the industry’s widest range of mini-breaker trip temperatures, from 55 °C up to 150 °C, and provide a trip temperature tolerance of ±5 °C The new Model SD Series are RoHS compliant and Bourns designed both families using its highest-rated corrosion resistant bimetal mechanism for better endurance in humid environments compared to standard TCO devices.

The SD Series’ advanced overtemperature protection technologies make them ideal solutions for a broad variety of applications such as automotive heaters (seats, steering wheel, doors, panels, camera, sensors, etc), actuator motors, charging cables, connectors, and printed circuit board components
