The CLA100E1200HB from Littelfuse/IXYS is a high-efficiency single SCR thyristor featuring 1200V repetitive peak reverse and forward blocking voltage and 100A average on-state current. It is designed for 50Hz/60Hz line-frequency rectification, AC power control, and high-current power-conversion systems. Its planar-passivated chip construction provides long-term stability and efficient conduction performance.
The device has a maximum on-state voltage of 1.34V at 100A, with a threshold voltage of 0.82V and a slope resistance of 5.2mΩ for power-loss calculations. These characteristics help reduce conduction losses in high-current applications.
CLA100E1200HB supports a non-repetitive peak surge current of approximately 1100A, a critical off-state voltage rise rate of 1000V/μs, and a repetitive critical on-state current rise rate of 150A/μs. These ratings make it suitable for motor soft starters, rectifiers, converters, and power-control systems exposed to high inrush currents.
Maximum gate-trigger current is 40mA at 25°C and 80mA at -40°C, while maximum gate-trigger voltage is 1.5V at 25°C. Maximum latching current is 150mA, and maximum holding current is 100mA. The gate-drive circuit should provide sufficient trigger-current margin under all operating conditions.
The component is supplied in an industry-standard three-lead TO-247AD through-hole package, with the mounting tab electrically connected to the anode. Junction-to-case thermal resistance is 0.2K/W, and case-to-heatsink thermal resistance is 0.15K/W. The operating-temperature range is -40°C to +125°C, with a maximum virtual junction temperature of 150°C.
The device is RoHS compliant, uses UL 94V-0-rated epoxy, and is supplied in tube packaging with 30 units per tube.
