INFINEON (International Rectifier)
IR Company (International Rectifier, acquired by Infineon) was established in 1947 and is an established power semiconductor manufacturer. Over the past fifty years, International Rectifier has achieved many world firsts in the semiconductor industry: Released the first commercial Zener diode and solar cell in 1958 Released the first silicon controlled rectifier device in 1959 (SCR) · In 1962, he took the lead in developing the epitaxial process to produce the most stable high-voltage SCR in the industry. In 1974, he used the glass passivation process to produce power transistors and high-power Darlington tubes. In 1979, he sold the first hexagonal- celled power MOSFET · Released the first smart power IC and the first high-voltage power IC in 1983 · In 1996, the 4-mask MOSFET process was used for the first time to produce fifth-generation HEXFET power. #POWER #IC #MOSFET #VOLTAGE #SCR #INFINEON #EPITAXIAL Infineon Technologies AG
