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/VRRM 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 = 85°C 4 A Lxx04Ry / Lxx04Vy T C = 75°C I TSM Non repetitive surge peak on-state current (full cycle, T J initial = 25°C) f = 50 Hz t = 20 ms 33 A f = 60 Hz t = 16.7 ms 40 I2t I2t Value for fusing t p = 8.3 ms 6.6 A2s di/dt Critical rate of rise of on-state current (I G = 50mA with ≤ 0.1μs rise time) f = 120 Hz T J = 110°C 50 A/μs I GTM Peak gate trigger current t p ≤ 10 μs T J = 110°C 1.2 A P G(AV) Average gate power dissipation T J = 110°C 0.3 W T stg Storage temperature range -40 to 150 °C T J Operating junction temperature range -40 to 110 °C 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 • RoHS Compliant • Glass – passivated junctions • Voltage capability up to 1000 V • Surge capability up to 55 A • Electrically isolated “L-Package” is UL recognized for 2500Vrms • 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 of sine wave • Requires only a small gate activation pulse in each half-cycle Agency Approval Agency Agency File Number ® L Package : E71639 ® |
