Product details

26V bidirectional TVS – 600W peak pulse in DO-214AA

Single bidirectional channel means one part protects both polarities — no need to series two unidirectional devices for AC or bipolar signal lines. The 28.9V minimum breakdown voltage gives a 2.9V margin above the 26V standoff, which keeps the diode out of conduction during normal rail ripple.

Clamp voltage and surge current — the numbers that matter

At the peak pulse current of 14.25A (10/1000µs), the clamping voltage rises to 42.1V maximum. No power line protection feature — this is a general-purpose TVS for signal and low-power DC rails, not a primary AC mains protector.

The SMB footprint is common across many TVS families, so the board layout is compatible with other SMB-packaged 600W TVS diodes from other manufacturers if a second-source need arises.

Frequently asked questions

Is the SMBJ26CA bidirectional or unidirectional?

Bidirectional — one channel that clamps both polarities. Use it on AC-coupled lines, bipolar supplies, or any rail where the transient can swing positive or negative relative to ground.

Can the SMBJ26CA replace the SMBJ24CA?

The SMBJ24CA has a 24V reverse standoff (typ) versus 26V for the SMBJ26CA. If your rail is 24V nominal, the SMBJ26CA provides 2V more headroom but also a higher clamp voltage. Check the downstream circuit's voltage tolerance before swapping — the SMBJ26CA clamps at 42.1V max versus a lower value for the SMBJ24CA.

Is the SMBJ26CA RoHS compliant?

RoHS compliance is standard for KYOCERA AVX's SMBJ series. The part is lead-free and meets the RoHS directive — confirm the specific date-code compliance with your order.
