D1213A-01SO-7

Diodes Incorporated · TVS · SOT-23

D1213A-01SO-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 CH1 passive ESD-protected channel input with 0.85pF typical capacitance (1.2pF max), clamped by steering diodes to VP and VN, with DC input range of (VN - 0.5) to (VP + 0.5) V.
2 VP passive Positive supply/reference rail of the TVS array, operating range 3.3V typical to 5.5V max with a maximum rating of 6.0V (VP - VN) and 8.0uA maximum supply current at 3.3V.
3 VN passive Negative reference rail of the TVS array, normally connected to ground (VN = 0V in the test conditions).
