It is a Triac and DIAC in a single package, which saves user expense by eliminating the need for separate Triac and DIAC components. Standard type devices normally operate in Quadrants I & III triggered from AC line. Alternistor type Quadracs are used in circuits requiring high dv/dt capability. ## LO **Features & Benefits** **Agency Approval** LE Agency Agency File Number **®** L Package : E71639 ~~EE~~ - RoHS Compliant • Surge capability up to 200 A - • Glass – passivated junctions - Voltage capability up to 600 V **==> picture [504 x 90] 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 [243 x 150] intentionally omitted <==** **----- Start of picture text -----**
