# AZ1015-02S

**TECH PUBLIC** · ESD And Surge Protection (TVS/ESD) · SOT-23-5

AZ1015-02S from TECH PUBLIC, in a SOT-23-5. 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 | NC | unconnected | No connect; the pin is not connected to the internal diode array in the pin configuration diagram. |
| 2 | GND | power_in | Ground reference for the TVS diode array; internally tied to the diode steering network and the zener cathode/anode return. |
| 3 | I/O 1 | passive | Protected data line 1 with low-capacitance steering diodes (0.6 pF typ, 1.1 pF max IO to IO), rated for ±30 kV ESD contact and air discharge. |
| 4 | I/O 2 | passive | Protected data line 2 with low-capacitance steering diodes (0.6 pF typ, 1.1 pF max IO to IO), rated for ±30 kV ESD contact and air discharge. |
| 5 | VDD | power_in | Positive supply/rail pin connected to the TVS zener, with 5 V max reverse working voltage and 6 V min breakdown at 1 mA. |
