Product details

What the 17V standoff and 30.5V clamp mean for your rail

When a transient hits, it clamps at 30.5V maximum while shunting 19.7A of peak pulse current in the standard 10/1000µs waveform. For a 17V bus — say a 12V system with margin or a 15V regulated rail — the standoff gives you headroom before the diode starts to leak. The clamp at 30.5V means downstream components rated for 30V or higher survive the transient.

Package and mounting — DO-214AA SMB on tape and reel

The DO-214AA (SMB) package is a standard surface-mount outline for TVS diodes. The /TR13 suffix confirms it ships on Tape & Reel, which is the format pick-and-place lines expect.

Microchip lists the SMBJ17CE3/TR13 as Active.

Frequently asked questions

Is SMBJ17CE3/TR13 bidirectional?

Yes, it is a single bidirectional channel, meaning it clamps both positive and negative transients symmetrically. That makes it a direct fit for AC-coupled signal lines or DC rails where reverse polarity protection is not already in place.

What is the closest pin-compatible alternative in the same family?

Within the SMBJ series, the SMBJ17A (unidirectional) and SMBJ17CA (bidirectional) share the same DO-214AA footprint and 17V standoff. The key difference is the clamping voltage and peak current — check the specific datasheet values for your transient energy budget.
