P4SMA6.8CA is a 400W bidirectional TVS diode in a DO-214AC (SMA) package for surge protection. Finding a replacement requires matching its 5.8V standoff voltage, package, and power ratings.

AI replacement insight

Electrical riskmedium

Candidates have different standoff voltages and peak current ratings that must be verified for the application.

Package risklow

Several alternatives exist in the same DO-214AC (SMA) package.

Sourcing risklow

The SMAJ and P4SMA series are widely available from multiple vendors.

Can it be replaced directly?

No direct drop-in replacement has been identified. All candidates have parametric differences that require engineering evaluation.

Best replacement path

Parametric alternatives in the same SMA package, like SMAJ6.5CA, are the closest path but require review of voltage and current ratings.

Main risk

The main risk is a mismatch in standoff voltage or peak current rating, which could lead to inadequate circuit protection or false clamping.
