Product details

Active 600W Zener TVS in DO-214AA

It delivers 600W peak pulse power per the 10/1000µs waveform, clamping at 23.8V max on a 25.2A peak pulse current. The 13V reverse standoff voltage suits 12V nominal rails, while the 14.4V minimum breakdown ensures the device stays off during normal operation. Packaged in DO-214AA (SMB) for surface-mount assembly, supplied on Tape & Reel.

Clamping and breakdown margins

The 14.4V minimum breakdown sits comfortably above the 13V standoff, giving margin against transient noise on a 12V bus without false triggering. Single unidirectional channel, no power-line protection — this is a signal-rail or low-side TVS, not for AC mains or high-energy bus clamping.

For a drop-in parametric match within the same package, the SMBJ13A (unidirectional, 13V standoff, 600W) from other brands may be evaluated — but always verify the clamping and breakdown specs against your rail tolerance before substituting.

Frequently asked questions

Is SMBJ13E3/TR13 equivalent to SMBJ13A?

Both are 600W unidirectional Zener TVS diodes with a 13V reverse standoff and the same DO-214AA footprint. The SMBJ13A typically has a 14.4V min breakdown and 23.8V clamping — same as this part. However, the suffix indicates Microchip's own part numbering; always compare the full datasheet curves (breakdown tolerance, clamping at temperature) before substituting across brands.
