LX807MBRP

Littelfuse · TRIACs · SOT-89

LX807MBRP from Littelfuse, in a SOT-89. Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 G input Gate terminal; gate trigger current IGT is max 5 mA in quadrants I-II-III and 7 mA in quadrant IV at VD = 12 V for the LX807 type, with max VGT of 1.3 V.
2 MT2 passive Main terminal 2, labeled Anode in the SOT-89 drawing and electrically connected to the tab; the device is a 0.8 A RMS triac with VDRM/VRRM of 600 V for the LX807MB.
3 MT1 passive Main terminal 1, labeled Cathode in the SOT-89 drawing and used as the reference for all gate polarities; IT(RMS) is 0.8 A at TC = 60°C.
