# D1213A-01LP

**TECH PUBLIC** · Electrostatic And Surge Protection (TVS/ESD) · DFN1006-2

D1213A-01LP from TECH PUBLIC, in a DFN1006-2. 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 | Terminal 1 of the 1-line uni-directional TVS diode, shown at the top of the pin configuration schematic; the datasheet gives Reverse Working Voltage VRWM 3.3 V max, Breakdown VBR 4.2 V min at 1 mA, and Junction Capacitance 0.45 pF typ / 0.5 pF max (VR = 0 V, 1 MHz, Pin 1 to Pin 2). |
| 2 | 2 | passive | Terminal 2 of the 1-line uni-directional TVS diode, shown at the bottom of the pin configuration schematic and forming the other end of the protected line with Pin 1; the datasheet gives Clamping Voltage 10 V at Ipp = 1 A and 15 V at Ipp = 4 A (8x20 us pulse). |
