# IP4234CZ6

**Nexperia** · ESD And Surge Protection (TVS/ESD) · TSOP-6

IP4234CZ6 from Nexperia, in a TSOP-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 channel 1 | passive | ESD protection I/O channel 1 (rail-to-rail π-filter diode path) with 3.1 pF typical and 3.8 pF maximum capacitance to ground, and 100 nA maximum reverse leakage at VI = 3.0 V, protecting to ±8 kV contact discharge per IEC 61000-4-2 level 4. |
| 2 | GND | power_in | Ground reference pin; the input voltage limit is stated relative to GND as GND − 0.5 V minimum to +5.5 V maximum. |
| 3 | I/O channel 1 | passive | ESD protection I/O channel 1 (second terminal of channel 1) with 3.1 pF typical and 3.8 pF maximum capacitance to ground, and 100 nA maximum reverse leakage at VI = 3.0 V, protecting to ±8 kV contact discharge per IEC 61000-4-2 level 4. |
| 4 | I/O channel 2 | passive | ESD protection I/O channel 2 with 3.1 pF typical and 3.8 pF maximum capacitance to ground, and 100 nA maximum reverse leakage at VI = 3.0 V, protecting to ±8 kV contact discharge per IEC 61000-4-2 level 4. |
| 5 | VCC | power_in | Supply voltage pin tied to the integrated Zener diode (pin 5 to pin 2), with 6 V to 9 V breakdown at 1 mA and 40 pF typical capacitance to ground. |
| 6 | I/O channel 2 | passive | ESD protection I/O channel 2 (second terminal of channel 2) with 3.1 pF typical and 3.8 pF maximum capacitance to ground, and 100 nA maximum reverse leakage at VI = 3.0 V, protecting to ±8 kV contact discharge per IEC 61000-4-2 level 4. |
