Littelfuse has upgraded its switching thyristor line with the introduction of the SJ Series High Temperature SCR (Silicon-Controlled Rectifier) Switching Thyristors. This new series offers circuit designers blocking voltages (VDRM) up to 600V and current ratings from 4-40A to support a wide range of applications. By offering designers a wider operating margin than earlier SCRs, they make it possible to tolerate insufficient cooling and higher inrush currents at startup.
Typical applications for SJ Series include:
“The SJ Series SCR Switching Thyristors’ high junction temperature of 150°C ensures a wider operating margin, allowing devices in compact packages to provide performance comparable with those in larger packages,” said Koichiro Yoshimoto, Business Development Manager for the Semiconductor Business Unit at Littelfuse.
“That allows designers to achieve higher performance by replacing existing SCRs with new ones with the same package size or they can reduce product size by using SCRs in the more compact packages.”
SJ Series SCR Switching Thyristors offer these key benefits:
Robust clip-attach package design enables high surge capability, so SCRs can tolerate high inrush currents and harsher operating conditions for a longer field life.
