Product details

70V rail clamp in a rework-friendly SMA package

It handles a 500W peak pulse (10/1000µs waveform) and clamps at 125V max at 4A.

Clamping voltage and peak pulse power

The clamping voltage of 125V at 4A peak pulse current (10/1000µs) defines the protection ceiling — downstream components must survive that voltage for the pulse duration. The 500W peak pulse power rating is the energy-handling envelope for a single surge event.

Microchip lists the SMAJ70CE3/TR13 as Active.

Bidirectional — one device for both polarities

The DO-214AC (SMA) body is symmetrical — no orientation worry during pick-and-place.

Frequently asked questions

Is SMAJ70CE3/TR13 bidirectional?

Yes, it is a single bidirectional channel. It clamps both positive and negative transients symmetrically, so polarity does not matter during installation.

What package does SMAJ70CE3/TR13 come in?

It is supplied in a DO-214AC (SMA) surface-mount package, on tape and reel (TR). The SMA footprint is common and rework-friendly — hand-solder or hot-air removal is straightforward.
