The IXYS MCC19-16IO1B is a single-phase thyristor (SCR) module rated at 19A average on-state current and 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in a standard isolated module package with a base-plate optimized for heatsink mounting, this device is engineered for demanding phase-control and switching applications where consistent gate sensitivity, low on-state voltage drop, and high blocking voltage capability are critical. Its robust construction meets the thermal and electrical stress requirements common in continuous-duty industrial environments.

The MCC19-16IO1B is well suited for AC power control in industrial heating systems, soft-start motor drives, DC power supplies, battery chargers, and welding equipment. Its 1600V voltage class provides the necessary margin for line transients found in three-phase 690V distribution systems, while the 19A current rating covers a broad range of medium-power load control tasks. Engineers specifying thyristor modules for variable power regulators, lighting dimmers, or resistance furnace controllers will find this device a direct-fit solution with predictable switching characteristics.

Key Features of the MCC19-16IO1B:

• 1600V VDRM/VRRM blocking voltage rating provides robust margin against line-side transients in 690V three-phase systems
• 19A average on-state current (IT(AV)) supports medium-power phase-control and switching duties in continuous operation
• Isolated copper base-plate package enables direct heatsink mounting without additional isolation hardware, simplifying thermal stack design
• Low gate trigger current (IGT) ensures compatibility with standard logic-level and optocoupler-based firing circuits
• High surge current capability (ITSM) accommodates inrush events during load switching and system startup without device degradation
• Compliant with industry-standard module footprint for straightforward drop-in replacement of equivalent thyristor modules from multiple manufacturers

With a factory lead time of 43 weeks for new production, the MCC19-16IO1B presents a significant procurement challenge for MRO buyers, OEM production lines, and field service teams managing unplanned downtime. Long lead times on IXYS thyristor modules are increasingly common as legacy industrial equipment continues to depend on components that are no longer in high-volume production. ATI Accurate Technology maintains verified inventory of the MCC19-16IO1B specifically to bridge this gap, providing a reliable source for both emergency replacement and planned maintenance stock without the risk of extended production delays.

ATI Accurate Technology is based in Palmetto, Florida and specializes in power semiconductors including IGBTs, thyristors, diodes, and rectifier modules — with particular depth in hard-to-find and long-lead-time parts.
