# TPSP1326-01LTG

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOD-523

TPSP1326-01LTG from TECH PUBLIC, in a SOD-523. 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 | Bi-directional ESD protection terminal connected to the protected line, 6V max reverse working voltage, 20pF max junction capacitance. |
| 2 | 2 | passive | Second bi-directional ESD protection terminal (to the protected line or ground, since polarity is symmetric), 6V max reverse working voltage, ±30kV air and contact ESD per IEC 61000-4-2. |
