The Vishay VSKT162/14PBF is a dual SCR thyristor power module engineered for demanding phase-control and AC power regulation applications. Rated at 162A average on-state current and a 1400V repetitive peak off-state voltage (VDRM/VRRM), this module delivers reliable switching performance and high thermal efficiency in a compact, bolt-down form factor. Built to Vishay's PBF (lead-free) specification, the VSKT162/14PBF meets RoHS compliance requirements while maintaining the rugged electrical characteristics required for continuous-duty industrial service.

The VSKT162/14PBF is well-suited for a broad range of industrial power control applications including AC motor soft starters, resistance heating controllers, DC drive converters, crane and hoist controls, and uninterruptible power supplies (UPS). Its dual SCR configuration simplifies converter topologies, reducing component count in single-phase and three-phase bridge rectifier circuits. Engineers specifying equipment for steel processing, plastics extrusion, mining, marine propulsion, and HVAC systems routinely rely on this class of thyristor module for its combination of high current density and proven long-term reliability in harsh environments.

Key Features of the VSKT162/14PBF:

• 162A average on-state current (IT(AV)) with high surge current capability (ITSM) for robust overcurrent tolerance
• 1400V VDRM/VRRM repetitive peak off-state and reverse voltage rating for high-line and three-phase 690V applications
• Dual SCR (anti-parallel or series configurable) topology in a single isolated-base module package simplifies PCB and busbar design
• Low thermal resistance junction-to-case (Rth(j-c)) enabling efficient heat dissipation with standard heatsink mounting
• RoHS-compliant PBF (lead-free) construction meeting current environmental directives without derating
• Industry-standard module footprint ensuring form-fit-function compatibility with legacy designs and existing heatsink hardware

With a current factory lead time of 99 weeks from Vishay, procurement teams managing MRO inventory, OEM production schedules, or emergency equipment repairs cannot afford to wait on new production runs. The VSKT162/14PBF is a long-lead, high-demand component frequently required for drive system repairs and plant maintenance where downtime costs are measured in thousands of dollars per hour. ATI maintains stock of hard-to-find and long-lead thyristor modules precisely to bridge this gap — providing verified new OEM components when the factory pipeline simply cannot respond in time.
