Product details

The SMBJ13A100 is a Zener-type TVS diode from onsemi's SMBJ series, designed for general-purpose surge protection on a 13 V rail. The 14.4 V minimum breakdown voltage ensures the device triggers before the protected circuitry sees overvoltage, while the 21.5 V clamp holds the transient below typical downstream component ratings.

No official successor or direct replacement is recorded from onsemi.

The single unidirectional channel and surface-mount footprint simplify PCB layout for a single-rail clamp.

Frequently asked questions

What is the replacement for the onsemi SMBJ13A100?

onsemi has not published a direct replacement for the SMBJ13A100. For a functionally equivalent TVS, look for a 13 V standoff, 600 W peak pulse, unidirectional Zener in DO-214AA from other manufacturers — confirm the breakdown and clamping voltages match your rail before substituting.
