VCAN26A2-03SHE3-18

Vishay Intertech · TVS · SOT-23

VCAN26A2-03SHE3-18 from Vishay Intertech, in a SOT-23. 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 1 passive Protected line 1 of the 2-line bidirectional symmetrical ESD diode, protected against ±30 kV contact/air discharge with working range ±26.5 V, rated pin 1 to pin 3.
2 2 passive Protected line 2 of the 2-line bidirectional symmetrical ESD diode, protected against ±30 kV contact/air discharge with working range ±26.5 V, rated pin 2 to pin 3.
3 3 passive Common terminal of both protection diodes, the reference for pin 1 and pin 2 in the 150 W 8/20 μs peak pulse power and electrical characteristic ratings (works in either polarity).
