Semikron SKKD162/16 IGBT Module

Semikron SKKD162/16 | Robust Thyristor/Diode Module for High-Power Control

The Semikron SKKD162/16 is a high-reliability thyristor/diode module engineered for demanding industrial power conversion applications. Housed in the industry-standard SEMIPACK® 2 package, this module integrates a thyristor and a diode in a single, robust component. It is the go-to solution for engineers designing efficient AC voltage controllers, high-current rectifiers, and resilient motor soft starters where long-term operational stability is non-negotiable.

Technical Deep Dive: Engineered for Longevity and Reliability

The exceptional durability of the SKKD162/16 is not an accident; it's the result of deliberate design choices that directly address common failure points in power electronics.

• Pressure Contact Technology: Unlike conventional soldered modules, this device utilizes an advanced pressure contact technology. This design eliminates solder fatigue, a primary cause of module failure under thermal stress. For applications with frequent power cycles, such as motor soft starters or industrial heating controls, this translates directly to a significantly longer service life and reduced maintenance overhead.
• Glass Passivated Chips: The heart of the module—the silicon chips—are protected by a hermetic glass passivation layer. This robust seal shields the sensitive semiconductor junctions from humidity and contaminants, ensuring stable blocking voltage and low leakage currents throughout the module's entire operational lifespan, even in harsh industrial atmospheres.

Multi-Dimensional Application Scenarios

The unique features of the Semikron SKKD162/16 deliver tangible value across several key industrial applications:

• Industrial Motor Soft Starters: By precisely controlling the firing angle of the thyristors, the SKKD162/16 smoothly ramps up voltage to AC motors. This mitigates severe mechanical shock on gearboxes and conveyors and drastically reduces electrical inrush currents that can destabilize the power grid, enhancing the longevity of the entire motor-driven system.
• High-Power Rectifier Bridges: For DC power supplies, battery chargers, and electroplating systems, these modules can be configured to build highly efficient and cost-effective controlled rectifiers. Their high current handling and low forward voltage drop minimize conduction losses, leading to lower operating temperatures and reduced energy consumption.
• AC Voltage Controllers: In applications like large-scale industrial heating or architectural lighting control, the module's phase-angle control capability allows for precise power regulation. This not only provides the required process control but also optimizes energy usage compared to simple on/off control systems.

Selection Guidance: Half vs. Full Control

When selecting a power module, it's crucial to match the topology to the application. The SKKD162/16 is a half-controlled module (thyristor/diode). This makes it an excellent and cost-effective choice for two-quadrant applications like controlled rectifiers or AC controllers where current flow is unidirectional. For applications requiring four-quadrant operation, such as regenerative DC motor drives, a fully controlled module with two thyristors per leg would be necessary. If your system does not require regeneration, the SKKD162/16 simplifies gate drive design and reduces overall system cost.
