DT1452-02SOQ-7

Diodes Incorporated · TVS · SOT-23

DT1452-02SOQ-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 I/O 1 passive ESD-protected channel 1 input/output, clamped to VSS with 1.2pF typical capacitance, VBR 7V min, 12A peak pulse (8/20µs) and ±16kV IEC61000-4-2 contact/air.
2 I/O 2 passive ESD-protected channel 2 input/output, clamped to VSS with 1.2pF typical capacitance, VBR 7V min, 12A peak pulse (8/20µs) and ±16kV IEC61000-4-2 contact/air.
3 VSS power_in Common reference/ground pin of the TVS array to which both I/O channels are clamped.
