STMicroelectronics X040 Sensitive gate SCR and Z040 Triterminal bidirectional SCR are 750V devices designed for power regulation and switching applications. A unidirectional X040 sensitive gate SCR can conduct current in one direction and block current in the other. Bi-directional X040 triterminal bi-directional SCR conducts current in both directions and blocks current in both directions. The highly sensitive devices are suitable for use in household appliances, power tools and industrial systems and can drive up to 4A loads.
STMicroelectronics X040 sensitive gate SCR and Z040 Tri-terminal bidirectional SCR are available in Ecopack2-compliant DPAK and IPAK packages with a wide operating temperature range from -40°C to +125°C.
