DESD1CAN2SOQ-7

Diodes Incorporated · TVS · SOT-23

DESD1CAN2SOQ-7 from Diodes Incorporated, 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	PIN1	passive	ESD protection channel 1 (CAN data line), bidirectional TVS diode to common pin 3; VRWM 24V max, VBR 25.4V min at 1mA.
2	PIN2	passive	ESD protection channel 2 (CAN data line), bidirectional TVS diode to common pin 3; VRWM 24V max, VBR 25.4V min at 1mA.
3	PIN3	passive	Common connection of both TVS diodes, shown as pin 3 in the device schematic; connect to ground reference.
