5SHY3545L0016: Product OverviewThe 5SHY3545L0016 is a high-power IGBT (Insulated Gate Bipolar Transistor) module from ABB’s StakPak series, designed for robust performance in medium-voltage power electronic systems. This press-pack IGBT serves as a core switching element in voltage source converters (VSCs) used in applications such as medium-voltage variable frequency drives (VFDs) for industrial motors, static synchronous compensators (STATCOMs) for grid voltage stabilization, and other high-power conversion equipment. Its primary function is to switch high currents at high voltages with precise timing to synthesize controlled AC waveforms from a DC bus.The module utilizes a press-pack housing, which is a key differentiator from standard module packages. This design allows for double-sided cooling, enabling efficient heat dissipation from both sides of the semiconductor die. This is critical for managing the significant thermal losses generated during switching operations at high power levels. The housing is mechanically robust, allowing multiple devices to be pressed together in a stack configuration to be connected in series, thereby achieving the high voltage-blocking capabilities required for medium-voltage systems (typically in the multi-kilovolt range).

Core Features & Customer ValueThe press-pack design with double-sided cooling offers a significant advantage in thermal management. By extracting heat from both sides of the semiconductor, the power density of the converter can be increased, leading to more compact equipment designs. For end-users, this translates to a smaller physical footprint for drive cabinets and potentially lower cooling system requirements. The robust mechanical construction also enhances reliability under thermal cycling, which is a common stressor in power electronic equipment.A critical feature of the press-pack design is its failure mode. Unlike conventional modules that may fail to an open circuit, press-pack IGBTs are designed to fail to a short circuit. This is a safety-critical characteristic in series-stacked configurations used for high voltage. A short-circuit failure is more manageable and predictable, allowing system designers to implement bypass mechanisms. This prevents a single device failure from causing a catastrophic overvoltage condition across the entire stack, thereby increasing system availability and enabling fault-tolerant operation.Typical ApplicationsIn a medium-voltage variable frequency drive for a pump or fan, multiple 5SHY3545L0016 IGBTs are used in the inverter section. They switch the DC link voltage to create a variable frequency and amplitude AC output, enabling precise speed control of large industrial motors (in the MW range), leading to substantial energy savings.In a STATCOM, these IGBTs form part of a voltage source converter that injects or absorbs reactive power to stabilize grid voltage. Their fast switching capability allows for rapid response to grid disturbances, improving power quality and stability.
