Thyristors Surface Mount – 120V - 240V > MKP3V120, MKP3V240 MKP3V120, MKP3V240 Pb Description Bidirectional devices designed for direct interface with the ac power line. Upon reaching the breakover voltage in each direction, the device switches from a blocking state to a low voltage on−state. Conduction will continue like a Triac until the main terminal current drops below the holding current. The plastic axial lead package provides high pulse current capability at low cost. Glass passivation insures reliable operation. Features • High Pressure Sodium Vapor Lighting • Strobes and Flashers • Ignitors • High Voltage Regulators • Pulse Generators Axial Lead • Used to Trigger Gates of SCR’s and Triac • Indicates UL Registered − File #E128662 AXIAL LEAD • These are Pb−Free Devices CASE 59 STYLE 2 Functional Diagram Additional Information Datasheet Resources Samples © 2017 Littelfuse, Inc.
