**Diodes Incorporated** · ESD And Surge Protection (TVS/ESD) · TSOT-26

D1213A-04TS-7 from Diodes Incorporated, in a TSOT-26. 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 | bidirectional | ESD-protected channel 1 line, rated for IEC 61000-4-2 ±8kV contact and ±15kV air discharge, with channel input capacitance of 0.85pF typical and 1.2pF maximum. |
| 2 | VN | power_in | Negative supply/reference pin: operating supply voltage VP−VN is 3.3V to 5.5V, and all channel voltages are referenced to VN, with DC channel input limited to (VN − 0.5V) to (VP + 0.5V). |
| 3 | CH2 | bidirectional | ESD-protected channel 2 line, rated for IEC 61000-4-2 ±8kV contact and ±15kV air discharge, with channel input capacitance of 0.85pF typical and 1.2pF maximum. |
| 4 | CH3 | bidirectional | ESD-protected channel 3 line, rated for IEC 61000-4-2 ±8kV contact and ±15kV air discharge, with channel input capacitance of 0.85pF typical and 1.2pF maximum. |
| 5 | VP | power_in | Positive supply pin: operating supply voltage VP−VN is 3.3V to 5.5V, with an absolute maximum of 6.0V. |
| 6 | CH4 | bidirectional | ESD-protected channel 4 line, rated for IEC 61000-4-2 ±8kV contact and ±15kV air discharge, with channel input capacitance of 0.85pF typical and 1.2pF maximum. |
