{"product_id":"vskt91-14-vishay","title":"VSKT91\/14-VISHAY","description":"\u003cp\u003eThe Vishay VSKT91\/14 is a dual SCR (silicon controlled rectifier) thyristor module engineered for demanding industrial power conversion applications. Rated at 91A average on-state current and 1400V repetitive peak reverse voltage (VRRM), this module delivers robust controllable rectification in a compact, isolated base package. Its press-fit or screw-mount construction simplifies integration into existing heatsink assemblies, and Vishay's proven thyristor technology ensures consistent gate sensitivity and thermal performance across the full operating range.\u003c\/p\u003e\u003cp\u003eThe VSKT91\/14 is widely deployed in AC motor soft-starters, variable speed drives, industrial DC power supplies, battery chargers, electrochemical processing equipment, and crane and hoist control systems. Its 1400V voltage class provides the necessary margin for 690VAC line-connected applications where transient overvoltages are common. Industries including steel, mining, marine propulsion, oil and gas, and heavy manufacturing rely on this class of SCR module to manage high-power loads with precise phase-angle control and reliable commutation.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eQuick Reference: VSKT91\/14\u003c\/strong\u003e\u003c\/p\u003e\u003ctable\u003e\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003ePart Number\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVSKT91\/14\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eManufacturer\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eVishay\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eType\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eDual SCR Thyristor Module\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCurrent (IT(AV))\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e91A\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eVoltage (VRRM)\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003e1400V\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eAvailability\u003c\/strong\u003e\u003c\/td\u003e\n\u003ctd\u003eIn Stock — Same-Day Shipping\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd\u003e\u003cstrong\u003eCondition\u003c\/strong\u003e\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 VSKT91\/14:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e91A average on-state current (IT(AV)) with high surge current (ITSM) capability for demanding load profiles\u003c\/li\u003e\n\u003cli\u003e1400V repetitive peak reverse voltage (VRRM) providing reliable margin on 690VAC three-phase systems\u003c\/li\u003e\n\u003cli\u003eDual SCR configuration in a single isolated-base module simplifies circuit layout for anti-parallel or bridge topologies\u003c\/li\u003e\n\u003cli\u003eLow thermal resistance (Rth(j-c)) enabling efficient heat transfer to external heatsinks and maximizing continuous power handling\u003c\/li\u003e\n\u003cli\u003eHigh gate sensitivity with well-defined trigger characteristics for consistent phase-angle firing across full current range\u003c\/li\u003e\n\u003cli\u003eIsolated copper base plate rated for full dielectric isolation, reducing system complexity and eliminating the need for additional insulating hardware\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003eWith a current factory lead time of 99 weeks from Vishay, procurement teams sourcing the VSKT91\/14 for new builds, field replacements, or MRO inventory face a significant supply challenge. Legacy industrial equipment — soft-starters, DC drives, and rectifier panels — often cannot wait nearly two years for new production. ATI specializes in exactly this scenario: maintaining verified stock of long-lead-time, hard-to-find, and discontinued SCR modules so that production lines stay running and capital equipment is not prematurely retired due to a single unavailable component.\u003c\/p\u003e\u003cp\u003eATI Accurate Technology is a power semiconductor distributor based in Palmetto, Florida, stocking IGBTs, thyristors, diodes, and rectifier modules for immediate fulfillment. Orders placed before 5PM EST ship same day. Whether you need a single replacement unit or volume pricing for a larger procurement, our team is ready to help.
