The EUPEC TT105N16LOF is a professional-grade thyristor module rated for 105A average on-state current and a 1600V repetitive peak off-state voltage. Engineered for high-reliability power conversion, this module integrates thyristor die in a compact, isolated baseplate package suitable for demanding thermal management schemes. Its robust construction meets the performance expectations of OEM equipment designers and field engineers alike, offering stable triggering characteristics, low on-state voltage drop, and the thermal cycling endurance required in continuous industrial duty cycles.

The TT105N16LOF is well suited to a broad range of industrial power electronics applications including AC motor soft starters, DC motor drives, regenerative drive systems, resistance heating controls, and industrial UPS platforms. It is also found in welding equipment, crane and hoist drive systems, and process control rectifiers where high blocking voltage and reliable phase-angle control are critical. EUPEC thyristor modules of this class remain a standard specification component across legacy and current-generation equipment in steel, mining, oil and gas, and heavy manufacturing sectors.

Quick Reference: TT105N16LOF

Key Features of the TT105N16LOF:

• 105A average on-state current (IT(AV)) with 1600V repetitive peak off-state voltage (VDRM/VRRM)
• Isolated copper baseplate for direct heatsink mounting and efficient thermal dissipation
• Low on-state voltage drop (VTM) minimizing conduction losses in continuous duty operation
• High surge current capability (ITSM) providing resilience against transient overload conditions
• Stable gate trigger characteristics with defined IGT and VGT parameters for predictable firing in phase control circuits
• Compact module footprint compatible with standard EUPEC mounting configurations and legacy drive system form factors

With a factory lead time of 99 weeks on new production, the TT105N16LOF presents a serious procurement challenge for any facility facing unplanned downtime or scheduled maintenance. Extended lead times of this magnitude are increasingly common across the EUPEC thyristor module line as legacy part numbers age out of active production cycles. For maintenance engineers managing aging drive infrastructure or procurement teams supporting MRO and capital spares programs, waiting nearly two years for a replacement is not operationally viable. ATI stocks these modules specifically to close that gap and return equipment to service fast.
