High-temperature SCRs

22 February 2017 Power Electronics / Power Management

High-temperature silicon-controlled rectifiers (SCRs) 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 and/or reduce costs by using smaller heatsinks. Addressing a wide range of industrial and two- and three-wheel vehicle applications, ST’s high-temperature SCRs are particularly well suited to voltage regulators in markets where cost efficiency and high reliability are key requirements.

Operating with junction temperatures of up to 150°C, the TN4015H SCRs offer on-state RMS current ratings of 40 A, extending and complementing the existing 12 A – 20 A product range. 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. The new SCRs are also more gate-sensitive compared with previous generations, while delivering best-in-class electrical noise immunity.
