New high-temperature SCRs (Silicon-Controlled Rectifiers) from STMicroelectronics allow manufacturers of voltage regulators, inrush current limiters for switch-mode power supplies, motor-control circuits, and industrial solid-state relays to improve the reliability of their applications or reduce costs by using smaller heatsinks.
Addressing a wide range of industrial and two/three-wheel vehicle applications, ST's high-temperature SCRs are particularly well suited to motorcycle voltage regulators in markets where low cost and high reliability are key requirements.
The new devices can operate with junction temperatures of up to 150°C and offer on-state RMS current ratings of 12, 16, and 20A. They are designed to offer tight control of the gate triggering current, leading to enhanced reproducibility on the customers' assembly lines with corresponding improvements in the reliability of the end products.
Other key technical features include:
Several versions of the 12A, 16A, and 20A devices are available now in volume production in TO-220AB and TO-220FPAB packages (also in D2PAK for the 12A device).
