{"product_id":"skkt500-16e-nbr","title":"SKKT500\/16E-NBR","description":"\u003cp\u003eThe SKKT500\/16E-NBR is a dual SCR (thyristor) power module rated for 500A average on-state current and a 1600V repetitive peak off-state voltage (VDRM\/VRRM). Housed in the industry-standard SKKT pressure-contact stud module package, it features a common cathode configuration optimized for three-phase bridge rectifier and AC phase-control circuits. With a low on-state voltage drop and stable gate trigger characteristics, this module is engineered for continuous heavy-duty operation in high-current industrial power conversion systems where thermal reliability and switching consistency are critical design requirements.\u003c\/p\u003e\u003cp\u003eThe SKKT500\/16E-NBR is well suited for demanding industrial applications including DC motor drives, crane and hoist controls, electrolytic process rectifiers, UPS systems, soft starters, and resistance welding equipment. Its 1600V voltage class provides adequate margin for 690V AC line inputs, while the 500A current rating supports high-power output stages without paralleling devices. This module is also found in legacy and retrofit installations across steel mills, mining equipment, marine propulsion systems, and large HVAC drive platforms where proven thyristor-based topologies remain in active service.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Reference: SKKT500\/16E-NBR\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003ePart Number\u003c\/td\u003e\n\u003ctd\u003eSKKT500\/16E-NBR\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eManufacturer\u003c\/td\u003e\n\u003ctd\u003eATI Accurate Technology\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eType\u003c\/td\u003e\n\u003ctd\u003eDual Thyristor (SCR) Module — Common Cathode\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCurrent Rating\u003c\/td\u003e\n\u003ctd\u003e500A (IT(AV))\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eVoltage Rating\u003c\/td\u003e\n\u003ctd\u003e1600V (VDRM \/ VRRM)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eAvailability\u003c\/td\u003e\n\u003ctd\u003eIn Stock — Same-Day Shipping\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003eCondition\u003c\/td\u003e\n\u003ctd\u003eNew OEM\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\u003c\/table\u003e\u003cp\u003e\u003cstrong\u003eKey Features of the SKKT500\/16E-NBR:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e500A average on-state current (IT(AV)) suitable for high-current rectifier and phase-control stages\u003c\/li\u003e\n\u003cli\u003e1600V VDRM\/VRRM repetitive peak voltage rating providing full margin on 690V AC three-phase inputs\u003c\/li\u003e\n\u003cli\u003eDual SCR common cathode configuration in a single module, reducing component count and bus complexity\u003c\/li\u003e\n\u003cli\u003eLow on-state voltage drop (VT) minimizing conduction losses and heat generation at full load\u003c\/li\u003e\n\u003cli\u003eIndustry-standard SKKT pressure-mount package ensuring drop-in compatibility with existing heatsink assemblies\u003c\/li\u003e\n\u003cli\u003eStable gate trigger sensitivity (IGT\/VGT) across operating temperature range for reliable firing circuit integration\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eThe SKKT500\/16E-NBR presents sourcing challenges across standard distribution channels due to long manufacturer lead times, product line consolidations, and the broad installed base of legacy equipment still requiring exact replacements. Procurement teams supporting aging drive platforms, process rectifiers, or OEM systems originally built around SKKT-series thyristor modules frequently encounter extended lead times of 16 to 52 weeks through conventional channels. ATI Accurate Technology maintains strategic inventory of hard-to-find and long-lead-time power semiconductor modules precisely to close these gaps and keep critical industrial equipment online without extended downtime.\u003c\/p\u003e\u003cp\u003eATI Accurate Technology is a power semiconductor specialist located in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules for immediate shipment.
