Product details

What this TVS diode clamps and how

For a 7V rail, the 13.3V clamping voltage means the TVS holds the transient to about 1.9× the standoff voltage — a tighter clamp than many general-purpose MOVs. The 45.1A peak pulse current at that clamp gives you the headroom to handle surges from inductive loads or lightning-coupled events on outdoor cabling.

Package, mounting, and storage

Supplied on tape & reel — store the reels dry; the DO-214AA body is not moisture-sensitive by default, but the reel label will list the MSL level if applicable.

Microchip lists this part as Active.

Frequently asked questions

Is SMBJ7.0CE3/TR13 bidirectional?

Yes, it has a single bidirectional channel, clamping both positive and negative transients. No need for series diodes on AC or bipolar rails.

What is the peak pulse power rating of SMBJ7.0CE3?

600W peak pulse power for a 10/1000µs waveform. The clamping voltage at that power is 13.3V max at 45.1A peak pulse current.

What is the closest pin-compatible alternative to SMBJ7.0CE3/TR13?

Within the same SMBJ family, the SMBJ7.0A (unidirectional) and SMBJ7.0CA (bidirectional) are direct alternatives in the same DO-214AA package. The SMBJ7.0CE3/TR13 is the tape-and-reel variant; the SMBJ7.0CA is a common cross-reference. Confirm the breakdown voltage tolerance and clamping specs match your application.
