2014 Littelfuse, Inc. Specifications are subject to change without notice. Revised: 12/14/14 Teccor brand Thyristors 4 Amp Sensitive & Standard Triacs Lxx04xx & Qxx04xx Series Description Main Features 4 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. Sensitive type devices guarantee gate control in Quadrants I & IV needed for digital control circuitry. Standard type devices normally operate in Quadrants I & III triggered from AC line. Symbol Value Unit I T(RMS) 4 A V DRM /V RRM 400 to 1000 V I GT (Q1) 3 to 25 mA Absolute Maximum Ratings - Sensitive Triacs (4 Quadrants) Symbol Parameter Value Unit I T(RMS) RMS on-state current (full sine wave) Lxx04Ly / Lxx04Dy T C = 85C 4 A Lxx04Ry / Lxx04Vy T C = 75C I TSM Non repetitive surge peak on-state current (full cycle, T J initial = 25C) f = 50 Hz t = 20 ms 33 A f = 60 Hz t = 16.7 ms 40 I 2 t I 2 t Value for fusing t p = 8.3 ms 6.6 A 2 s di/dt Critical rate of rise of on-state current (I G = 50mA with d 0.1 s rise time) f = 120 Hz T J = 110C 50 A/ s I GTM Peak gate trigger current t p d 10 s T J = 110C 1.2 A P G(AV) Average gate power dissipation T J = 110C 0.3 W T stg Storage temperature range -40 to 150C T J Operating junction temperature range -40 to 110C Note: xx = voltage, y = sensitivity Schematic Symbol MT2 MT1 G Applications Typical applications are AC solid-state switches, power tools, home/brown goods and white goods appliances. Sensitive gate Triacs can be directly driven by microprocessor or popular opto-couplers/isolators. Internally constructed isolated packages are offered for ease of heat sinking with highest isolation voltage. Features & Benefits junctions 1000 V 55 A recognized for 2500Vrms eliminates arcing or contact bounce that create voltage transients from reaction of switching events generation, depending on activation point of sine wave activation pulse in each half-cycle Agency Approval Agency Agency File Number L Package : E71639 RoHS
