Technical Deep Dive: The Foundation of Reliability
The SEMIKRON SKKE162/16 isn't just another power module; its design is centered on longevity and thermal stability. This is achieved through specific, field-proven technologies that directly address common failure points in industrial power systems.
Glass Passivated Thyristor Dies
At the heart of the SKKE162/16 are its thyristor chips, which undergo a glass passivation process. This creates a hermetic, inorganic seal around the sensitive semiconductor junction. Application Value: This technique provides superior protection against moisture and contaminants, drastically improving long-term voltage blocking stability and reducing the risk of failure in humid or polluted factory settings. The result is a component you can trust for continuous, multi-year operation without degradation.
Isolated Copper Baseplate Technology
The module utilizes a Direct Bonded Copper (DBC) substrate, which serves as both an electrical insulator and a thermal conductor. This design offers 2500V isolation while providing an exceptionally low thermal resistance path from the silicon die to the heatsink. Application Value: For system designers, this simplifies thermal management. It ensures efficient heat dissipation, allowing the module to run cooler and more reliably under heavy loads. This also simplifies assembly by eliminating the need for separate, often fragile, insulating pads, reducing installation complexity and potential points of failure.
Application-Specific Value of the SKKE162/16
The true strength of the SEMIKRON SKKE162/16 lies in how its features translate to tangible benefits across various industrial applications.
- Industrial Soft Starters: By using the SKKE162/16 for phase-angle control, you can smoothly ramp up motor voltage, eliminating the severe mechanical shock and electrical inrush currents associated with direct-on-line starting. This extends the lifespan of motors, gearboxes, and couplings, significantly reducing maintenance costs.
- AC Voltage Controllers: In applications like large-scale industrial heating or lighting control, the module's robust back-to-back SCR topology delivers precise and reliable power regulation. Its high surge current capability (ITSM) easily handles the demands of resistive and inductive loads.
- Controlled Rectifiers: When used as the front-end for DC power supplies or variable frequency drives, the SKKE162/16 enables the creation of a stable, regulated DC bus from an AC source. Its thermal efficiency ensures dependable operation, which is critical for processes that cannot afford unexpected downtime.

Frequently Asked Questions (FAQ)
- What is the primary difference between this SKKE162/16 thyristor module and an IGBT module?The SKKE162/16 is built with Thyristors (SCRs), which are ideal for low-frequency (line frequency) phase-angle control of AC power and rectification. In contrast, an IGBT inverter module is designed for high-frequency switching (in the kHz range) to create AC waveforms from a DC source, as seen in modern VFDs and solar inverters. They serve fundamentally different purposes in a power conversion system.
- What is the significance of the "glass passivated" feature for my application?Glass passivation provides a rugged, hermetic seal at the chip level. If your equipment operates in environments with temperature fluctuations, high humidity, or industrial airborne particles, this feature ensures the module's high-voltage blocking capability remains stable over its entire lifespan, preventing premature failures and enhancing overall system reliability.
