## **Features** - High static dV/dt - High dynamic commutation - 150 °C maximum Tj - Three quadrants - Built-in ceramic for tab insulation - Compliance to UL1557 standard (ref : E81734) - ECOPACK[®] 2 compliant component - Complies with UL94,V0 - Surge capability VDSM, VRSM = 900 V ## **Benefits** - Device is less likely to have false turn-on thanks to high dV/dt - Better turn-off in high temperature environments thanks to (dI/dt)c - Increase of thermal margin due to extended working Tj up to 150 °C - Better thermal resistance due to the ceramic inside the package Available in through-hole package, the T835T-8I Triac can be used for the on/off or phase angle control function in general purpose AC switching where high commutation capability is required. This device can be used without a snubber RC circuit when the limits defined are respected. TO-220AB insulated provides tab insulation, UL1557 certified, rated at 2.5 kV RMS and UL-94, V0 resin compliance. Package environmentally friendly ECOPACK[®] 2 graded (RoHS and Halogen Free compliance).
