Product Overview

• PN: 5SHY3545L0003
• Equivalent part code: 336A4954ARP1, 3BHB003154R0101
• Brand: ABB
• Series: 5SHY series IGCT high-power semiconductor components
• Type: Asymmetric Integrated Gate Commutated Thyristor Module

• FunctionIt serves as core power switching device inside ABB ACS5000 medium voltage three-level frequency converter. It undertakes DC bus chopping and AC inversion work, converts direct current into variable frequency alternating current to drive high-power motors such as large fans, water pumps and mine conveyors. Cooperating with dedicated trigger drive board, it realizes fast turn-on and turn-off control, suppresses grid impact current during motor startup, and supports energy feedback back to power grid in four-quadrant working condition. It adopts crimp press-fit packaging without internal solder joints, improving anti-vibration performance and heat conduction efficiency for long-term stable operation under heavy load.
