Best Alternatives to IP4220CZ6

Package: TSOP6LeiditechProgrammersNumber of Protected Lines: 4 I/O + 1 VccCapacitance (Typ): 0.3 pFReverse Working Voltage: 5 VClamping Voltage (Typ): 8.5 VResponse Time: < 1 ns

IP4220CZ6 is a 4-line, 5V low-capacitance TVS array for ESD protection in high-speed interfaces. Finding a substitute requires matching the SOT23-6 package, 0.3pF capacitance, and 300W power rating.

AI replacement insight

Electrical riskhigh

Using a part with higher capacitance or lower power can lead to signal degradation or protection failure.

Package riskmedium

Pinout must be verified. Incorrect pin mapping will cause circuit failure.

Firmware risklow

This is a passive component with no firmware interaction.

Can it be replaced directly?

Direct replacement for IP4220CZ6 should use only Datasheet verified or Strong match candidates; many approved options still require engineering review.

Best replacement path

USBLC6-4SC6 offers the closest parametric match and should be the first part to evaluate.

Main risk

The primary risk is pinout incompatibility, even with a matching package. A secondary risk is selecting a part with higher capacitance or a lower power rating.
