ABB 5SHY5045L0020 belongs to ABB 5SHY high power asymmetric IGCT family. This pressure contact power semiconductor integrates GCT chip and anti-parallel freewheeling diode, supporting large current and high voltage switching. It is designed for medium voltage inverter, rectifier and grid power conditioning equipment with outstanding thermal stability and anti-shock capability.

5SHY stands for ABB asymmetric IGCT series. 50 means rated continuous current 5000A, 45 represents rated blocking voltage 4500V. L0020 is version code for production identification, ordering and stock management. Alternative part codes:5SXE08-0167,3BHE014105R0001.

Rated repetitive off-state blocking voltage reaches 4500V and rated continuous current is 5000A. Typical on-state voltage is below 2.2V under rated load. Usable switching frequency ranges from 200Hz up to 1000Hz. Operating junction temperature covers -40°C to +175°C. Water cooling is the standard cooling solution. Adopts press-fit pressure contact package with overall weight around 2.8kg and dimension about 240×180×60mm.

Equipped with main high-current power terminals and independent dedicated gate drive terminals. Gate port matches ABB special gate drive unit with isolated driving design to suppress external electromagnetic interference. No extra communication port reserved, external control signal connects via matched dedicated driving board.

It completes high voltage large current circuit switch-on and switch-off for AC-DC and DC-AC power conversion. It provides rapid overcurrent shutdown protection against short-circuit fault of rear-end equipment. Low loss characteristic improves overall working efficiency of converter system. Pressure contact structure strengthens heat conduction and enhances long-term operational stability.

It is widely configured on ABB ACS6000 medium voltage drives for mining, metallurgy, oil gas and cement large motor control. Applied on large wind power converters and centralized photovoltaic inverter equipment. Used in power grid FACTS, SVC, STATCOM and partial HVDC conversion devices. Also applicable to heavy industry high power rectifier and industrial high-power UPS equipment.

Fix the module tightly on deionized water cooling heatsink with specified mounting torque and guarantee uniform pressing force. Use low inductance copper busbar for main power wiring and tighten terminals according to required torque value. Equip matched original ABB gate drive unit before commissioning and isolate high power wiring and gate signal wiring. Regularly inspect cooling water flow rate, water quality and pipeline leakage condition every quarter. No internal replaceable spare parts, whole module replacement is required once permanent hardware damage happens. Store and operate in dry environment away from violent vibration and corrosive gas.
