It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components. Q6012LTH1LED series is designed to meet low load current characteristics typical in LED lighting applications. By keeping holding current at 8mA maximum, this Quadrac series is characterized and specified to perform best with LED loads. The Q6012LTH1LED series is best suited for LED dimming controls to obtain the lowest levels of light output with a minimum probability of flickering. **==> picture [379 x 162] intentionally omitted <==** **----- Start of picture text -----**

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. **==> picture [246 x 458] intentionally omitted <==** **----- Start of picture text -----**
