SP720ABTG from Littelfuse, in a SOIC-16. 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 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 2 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 3 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 4 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 5 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 6 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 7 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 8 | V- | power_in | Negative supply pin; an input is clamped to V- when it falls one VBE diode threshold below V-, and the supply (V+) - (V-) operating range is 2V to 30V. |
| 9 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 10 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 11 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 12 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 13 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 14 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 15 | IN | input | Protected signal input that is clamped to V+ when it rises more than one VBE above V+, with a single-ended range to +30V and a differential range to ±15V. |
| 16 | V+ | power_in | Positive supply pin; the SCR clamp to V+ triggers at one VBE diode threshold above V+, and the supply (V+) - (V-) operating range is 2V to 30V with absolute maximum 35V. |
