Product details

What this TVS diode does on the board

It clamps transients up to 38.9V at 12.8A peak pulse current — enough to protect a 24V rail in industrial control or telecom gear from surge events without blowing the trace.

The 500W peak pulse power rating (10/1000µs) tells you how much energy the diode can absorb in a single surge — enough for IEC 61000-4-5 level 2 on a 24V supply. The 24V reverse standoff means the diode stays off below 24V, so it won't leak or load your rail during normal operation. Breakdown starts at 26.7V min, and clamping hits 38.9V max at 12.8A — that's the voltage the protected IC sees during the event.

Housed in a DO-214AC (SMA) package, this is a standard surface-mount footprint that reflows on a normal lead-free profile. The Tape & Reel delivery suits automated pick-and-place.

That means you can commit it to a BOM without planning a last-time buy or second-source qualification for the next few years.

Frequently asked questions

What is the peak pulse power of SMAJ24AE3/TR13?

500W peak pulse power, measured with a 10/1000µs waveform. That's the energy rating for a single surge event — enough for most industrial 24V rail protection needs.

Is SMAJ24AE3/TR13 RoHS compliant?

The evidence does not list a RoHS compliance statement for this specific order code. Verify with the manufacturer's datasheet or contact us with your compliance requirement — we can check the date code and lot certification on the sourced material.

What package does SMAJ24AE3/TR13 come in?

DO-214AC (SMA) surface-mount package, supplied on Tape & Reel. The footprint is standard for this package type — no special layout needed beyond the usual SMA pad geometry.

What is the closest pin-compatible alternative to SMAJ24AE3/TR13 in this Circuit Protection family?

The evidence does not list a specific cross-reference or equivalent for this order code. Within the SMAJ series, other voltage variants (e.g., SMAJ5.0A through SMAJ170A) share the same DO-214AC package and 500W rating, so a different voltage grade would be footprint-compatible. Confirm the 24V standoff requirement before substituting.
