The IXYS MCC19-08IO1B is a thyristor (SCR) power module designed for demanding phase-control and AC switching applications. Rated at 19A average on-state current and an 800V repetitive peak off-state voltage (VDRM/VRRM), this module delivers robust, gate-controlled rectification in a compact, isolated base package. Its thermally efficient construction enables direct heatsink mounting, simplifying thermal management in space-constrained enclosures. The MCC19-08IO1B is engineered to meet the reliability requirements of continuous industrial duty cycles, making it a dependable choice for engineers replacing failed modules or designing new power conversion stages.

The MCC19-08IO1B is well suited for a broad range of industrial power control applications. Typical deployments include AC motor soft starters, resistance heating controllers, power regulators, light dimming systems, and static AC switches where phase-angle firing control is required. It is also found in UPS input stages, battery chargers, and DC drive converters operating from single- or three-phase line voltages up to 800V. Its isolated base construction makes it interchangeable across a variety of existing drive and control platforms, reducing redesign effort during field replacements or system upgrades.

Key Features of the MCC19-08IO1B:

• 19A average on-state current (IT(AV)) with 800V repetitive peak off-state voltage for medium-power AC control circuits
• Isolated copper base plate for direct heatsink mounting, supporting efficient junction-to-case thermal dissipation
• Low on-state voltage drop (VTM) minimizes conduction losses in continuous phase-control duty
• Gate trigger current and voltage specifications compatible with standard SCR firing boards and gate driver ICs
• Compact IO1B power module package enables high-density PCB or bus-bar integration in drives and controllers
• Designed and qualified to IXYS reliability standards for long operational life in industrial environments

With a factory lead time of 39 weeks for new production, the MCC19-08IO1B presents a significant procurement challenge for maintenance teams dealing with unplanned failures or production line downtime. IXYS thyristor modules in the MCC series are widely deployed across legacy drive platforms and industrial controls, many of which are no longer in active production support. Waiting nearly ten months for a factory order is not a viable option for most operations. ATI Accurate Technology maintains inventory of hard-to-find and long-lead-time IXYS modules precisely to bridge this gap, providing immediate access when it matters most.
