# 82400102

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

82400102 from TECH PUBLIC, in a SOT-23-6. 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 I/O line 1, internally tied to pin 6, clamping at 9 V max for IPP = 1A and 12 V max for IPP = 9A (8/20µs). |
| 2 | GND | power_in | Ground reference of the TVS array; I/O-to-GND junction capacitance is 1.0 pF typ and 1.3 pF max at VR = 0V, f = 1MHz. |
| 3 | I/O 2 | passive | ESD-protected I/O line 2, internally tied to pin 4, with 5 V reverse working voltage max and ±30 kV air/contact ESD protection. |
| 4 | I/O 2 | passive | ESD-protected I/O line 2, internally tied to pin 3, with 5 V reverse working voltage max and ±30 kV air/contact ESD protection. |
| 5 | VDD | power_in | Positive supply/reference rail of the diode array to which the steering diodes clamp; operating voltage 5V. |
| 6 | I/O 1 | passive | ESD-protected I/O line 1, internally tied to pin 1, clamping at 9 V max for IPP = 1A and 12 V max for IPP = 9A (8/20µs). |
