SMBJ28CA AI Analysis:
Datasheet, Specs, Alternatives & ECAD

It features a 28V stand-off voltage, 600W peak pulse power, a breakdown voltage range of 31.1V to 34.4V, and a maximum clamping voltage of 45.4V.

It is commonly used in I/O interfaces, AC/DC power supplies, and low-frequency signal transmission lines (like RS232 or RS485) to protect against ESD and surge events.

Engineers should review the peak pulse power rating (10/1000μs waveform), the clamping voltage at the expected peak current, and the thermal derating requirements for the specific operating environment.

The component is widely available from multiple distributors and is currently in active production, presenting a low sourcing risk.
