# AOZ8904CIL

**Alpha Omega Semicon** · ESD And Surge Protection (TVS/ESD) · SOT-23-6

AOZ8904CIL from Alpha Omega Semicon, 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 | CH1 | bidirectional | Protected data line channel 1; the internal steering diodes clamp ESD and transients on this I/O to VP or VN, rated ±24kV for IEC 61000-4-2 contact and air and ±24kV HBM. |
| 2 | VN | power_in | Negative reference pin of the TVS and steering diodes (the ground-side clamp reference); the VP-VN absolute maximum is 6V and VRWM is 5.5V between pins 5 and 2. |
| 3 | CH2 | bidirectional | Protected data line channel 2; the internal steering diodes clamp ESD and transients on this I/O to VP or VN, rated ±24kV for IEC 61000-4-2 contact and air and ±24kV HBM. |
| 4 | CH3 | bidirectional | Protected data line channel 3; the internal steering diodes clamp ESD and transients on this I/O to VP or VN, rated ±24kV for IEC 61000-4-2 contact and air and ±24kV HBM. |
| 5 | VP | power_in | Positive reference pin of the internal TVS (low operating voltage of 5.0V per the features list); VP-VN absolute maximum is 6V, and the electrical characteristics are specified with VP floating or biased to 3.3V. |
| 6 | CH4 | bidirectional | Protected data line channel 4; the internal steering diodes clamp ESD and transients on this I/O to VP or VN, rated ±24kV for IEC 61000-4-2 contact and air and ±24kV HBM. |
