Product details

130V rail clamp — one device, both polarities

The single bidirectional channel means one component protects both positive and negative transients on the same line — no need for back-to-back series diodes. This simplifies PCB layout and reduces BOM count on AC signal lines or bipolar DC rails.

500W peak pulse — sizing the clamp for the surge

The 2.4A peak pulse current is the current the device can shunt during the clamp event — confirm your source impedance and surge waveform keep the peak current below this limit.

Frequently asked questions

Is SMAJ130CAE3/TR13 bidirectional or unidirectional?

Bidirectional — one channel. It clamps transients of either polarity on the same line, which is typical for AC-coupled signals or bipolar DC rails.

What is the peak pulse power (PPP) rating of SMAJ130CAE3/TR13?

500W for a 10/1000 µs waveform. This is the maximum power the device can dissipate during a single surge event.
