The SEMIKRON SKT160/16E is a phase-control thyristor module rated for 160A average on-state current and a 1600V repetitive peak off-state voltage (VDRM/VRRM). Housed in the industry-standard SKT package with isolated baseplate construction, this module is engineered for robust performance in high-power AC/DC conversion circuits. Its low thermal resistance and high surge current capability make it a proven choice in rectifier bridges, AC controllers, and soft-starter assemblies where long-term reliability under continuous load cycling is non-negotiable.

The SKT160/16E sees widespread deployment across heavy industrial platforms including DC motor drives, crane and hoist controls, resistance welding equipment, UPS systems, and electrochemical process rectifiers. Its voltage class and current rating align well with medium-voltage input stages in three-phase controlled rectifier topologies. The module is also specified in heating and temperature control systems, battery formation equipment, and traction auxiliary power supplies where phase-angle firing and precise power regulation are critical operational requirements.

Key Features of the SKT160/16E:

• 160A average on-state current (IT(AV)) with high surge current (ITSM) capability for fault-tolerant designs
• 1600V VDRM/VRRM voltage class suitable for 690V and higher AC input systems with adequate blocking margin
• Isolated copper baseplate construction enabling direct heatsink mounting without additional isolation hardware
• Low thermal resistance junction-to-case (RthJC) supporting high power density in space-constrained assemblies
• Gate trigger specifications optimized for compatibility with standard SCR firing boards and phase-control ICs
• SKT package footprint ensures form-fit-function interchangeability with equivalent modules from other qualified manufacturers

With a current factory lead time of 38 weeks for new production, the SKT160/16E presents a genuine procurement challenge for MRO teams managing planned shutdowns or OEMs building forward inventory. SEMIKRON thyristor modules in the 1600V class are routinely constrained due to wafer allocation and specialized assembly processes. Procurement professionals are advised to initiate purchase orders well ahead of scheduled maintenance windows. ATI Accurate Technology actively monitors distributor channels, broker networks, and factory pipelines to locate genuine stock of long lead time and allocated power semiconductors like the SKT160/16E.

ATI Accurate Technology is based in Palmetto, Florida and stocks a broad range of IGBTs, thyristors, diodes, and rectifier modules for same-day shipping on orders placed before 5PM EST.
