The Q4015L5 is a 15 Amp Standard TRIAC and part of the 15 A Standard & 16 A Alternistor (High Commutation) series from Littelfuse, Inc. This bi-directional solid-state switch is designed for AC switching and phase control applications, including motor speed control, lighting control, and static switching relays. The device operates in Quadrants I and III for standard types, while the Alternistor variant operates in Quadrants I, II, and III, making it suitable for circuits requiring high dv/dt capability.
Key specifications include a voltage capability of up to 1000 V and a surge capability of 200 A. The device features glass-passivated junctions and is RoHS compliant. The L package offers an isolation rating of 2500 V_RMS and is recognized to UL 1557 as an electrically isolated semiconductor device. The TRIAC requires only a small gate activation pulse in each half-cycle, which contributes to its solid-state switching advantages, such as eliminating arcing and contact bounce.
Applications for the Q4015L5 include AC solid-state switches, light dimmers, power tools, and appliances, particularly in scenarios with inductive loads that demand high commutation performance.
15 Amp and 16 Amp bi-directional solid state switch series is designed for AC switching and phase control applications such as motor speed and temperature modulation controls, lighting controls, and static switching relays.Standard type devices normally operate in Quadrants I & III triggered from AC line.Alternistor type devices only operate in quadrants I, II, & III and are used in circuits requiring high dv/dt capability. RoHS Compliant Glass-passivated junctions Voltage capability up to 1000 V Surge capability up to 200 A L-package is UL Recognized for an isolation voltage of 2.5 kVrms Solid-state switching eliminates arcing or contact bounce that create voltage transients No contacts to wear out from reaction of switching events Restricted (or limited) RFI generation, depending on activation point sine wave Requires only a small gate activation pulse in each half-cycle
