Silicon-controlled rectifiers (SCRs), also called thyristors, are semiconductor power devices with a four-layer three-way junction framework (PNPN). Because its intro in the 1950s, SCRs have been ...

Abstract: In this paper, a novel ring silicon-controlled rectifier (NRSCR) for electrostatic discharge (ESD) protection is proposed. Compared with conventional SCR, the trigger voltage of NRSCR is ...

STMicroelectronics announced a new high-temperature SCRs (Silicon-Controlled Rectifiers) that allow manufacturers of voltage regulators, inrush current limiters for switch-mode power supplies, ...
