The Infineon TT142N16KOF is a thyristor (SCR) module rated for 142A average on-state current and 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in Infineon's compact KOF industry-standard package, this module integrates two thyristors in a common-cathode or series configuration suitable for controlled rectifier and AC switching topologies. It is engineered for low thermal resistance, robust gate triggering, and high surge current capability — making it a dependable choice for engineers designing or maintaining high-power industrial equipment.

The TT142N16KOF is widely deployed in industrial AC motor drives, soft starters, resistance heating controllers, phase-angle power regulators, and UPS input rectifier stages. Its 1600V blocking voltage provides the necessary margin for 690VAC line voltages with transient headroom, while the 142A current rating suits medium-power converter stages in steel processing, plastics extrusion, crane drives, and mining equipment. Retrofit and board-level replacement applications are equally common given the prevalence of Infineon thyristor modules across legacy industrial platforms.

Quick Reference: TT142N16KOF

Key Features of the TT142N16KOF:

• 142A average on-state current (IT(AV)) with high surge current (ITSM) capability for robust overcurrent tolerance
• 1600V VDRM/VRRM repetitive peak blocking voltage, providing design margin on 690VAC three-phase systems
• Low thermal resistance junction-to-case (RthJC) enabling efficient heat transfer to chassis or liquid-cooled heatsinks
• Infineon KOF package with industry-standard footprint for direct drop-in replacement across multiple drive and rectifier platforms
• Isolated copper baseplate construction for reliable electrical isolation and consistent thermal contact with heatsink surfaces
• Gate-cathode characteristics optimized for reliable triggering with standard SCR gate drive circuits across specified temperature range

With a confirmed factory lead time of 99 weeks for new production, the TT142N16KOF represents exactly the type of long-lead-time, supply-constrained component that halts equipment repair and new builds alike. Whether you're maintaining legacy industrial machinery that depends on this exact module or managing procurement risk on a new design, waiting nearly two years for factory stock is not a viable option. ATI specializes in bridging this gap — maintaining inventory of hard-to-find Infineon thyristor modules so your production line or service schedule doesn't stall on a single component.
