K40H1203 IGBT Transistor 1200V 80A TO-247

Description

K40H1203 IGBT Transistor 1200V 80A TO-247 The K40H1203 is the marking for the IKW40N120H3, a third-generation high-speed IGBT from Infineon using TRENCHSTOP technology and fieldstop construction. It combines low collector-emitter saturation voltage with high-speed switching and includes an anti-parallel diode with soft, fast recovery characteristics. The datasheet specifies a maximum junction temperature of 175°C and a PG-TO247-3 package. This IGBT is designed for demanding power-electronics applications including uninterruptible power supplies, welding converters, and converters operating at high switching frequencies. The device supports high collector current capability and provides an integrated anti-parallel diode, making it suitable for power conversion stages where controlled switching and reverse-current handling are required. Features: High-speed IGBT technology. TRENCHSTOP technology. Fieldstop construction. Soft and fast recovery anti-parallel diode. Low conduction losses. Low EMI characteristics. Suitable for high-frequency switching. Integrated anti-parallel diode. Through-hole power package. RoHS-compliant lead plating.
