Teccor® brand Thyristors 8 Amp Alternistor Quadrac for LED dimmer applications Q6008LTH1LED Series RoHS ® Description The Quadrac is an internally triggered Triac designed for AC switching and phase control applications. It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components. Q6008LTH1LED series is designed to meet low load current characteristics typical in LED lighting applications. By keeping holding current at 6mA maximum, this Quadrac series is characterized and specified to perform best with LED loads. The Q6008LTH1LED series is best suited for LED dimming controls to obtain the lowest levels of light output with a minimum probability of flickering. Q6008LTH1LED series is offered in the industry standard TO-220AB package with an isolated mounting tab that makes it best suited for adding an external heat sink.

Good design practice should limit the maximum continuous current through the main terminals to 75% of the device rating. Other ways to ensure long life for a power discrete semiconductor are proper heat sinking and selection of voltage ratings for worst case conditions. Overheating, overvoltage (including dv/dt), and surge currents are the main killers of semiconductors. Correct mounting, soldering, and forming of the leads also help protect against component damage. tP TP Temperature Reflow Condition Ramp-up TL tL TS(max) Preheat TS(min) 25 Ramp-do Ramp-down tS time to peak temperature Time Environmental Specifications Test Specifications and Conditions MIL-STD-750: Method 1040, Condition A High Temperature Rated VDRM (VAC-peak), 110°C, 1008 Voltage Blocking hours MIL-STD-750: Method 1051 Temperature Cycling -40°C to 150°C, 15-minute dwell, 100 cycles Biased Temperature & EIA/JEDEC: JESD22-A101 Humidity 320VDC, 85°C, 85%RH, 1008 hours MIL-STD-750: Method 1031 High Temp Storage 150°C, 1008 hours Low-Temp Storage -40°C, 1008 hours Thermal Shock MIL-STD-750: Method 1056 0°C to 100°C, 5-minute dwell, 10-second transfer, 10 cycles Autoclave EIA/JEDEC: JESD22-A102 (Pressure Cooker Test) 121°C, 100%RH, 2atm, 168 hours Resistance to Solder Heat MIL-STD-750: Method 2031 260°C, 10 seconds Solderability ANSI/J-STD-002, Category 3, Test A Lead Bend MIL-STD-750: Method 2036, Condition E © 2014 Littelfuse, Inc.
