Product details

Clamping voltage and the protection threshold it sets

The SMAJ8.0A-13-F: Its 8 V reverse standoff voltage (VRWM) means the protected rail can run at 8 V DC without the diode conducting leakage current; the breakdown voltage range (8.89 V min) triggers clamping when a transient exceeds that threshold.

Peak pulse current and waveform reality

The 29.4 A peak pulse current (Ipp) is specified at the 10/1000 µs exponential waveform per the TVS test standard. A real-world surge — whether from ESD, inductive load dump, or coupled lightning — rarely matches this exact waveshape; the 400 W peak pulse rating is the energy the die can absorb in a single event. For repetitive transients, derate the peak power from the 25 °C rating using the temperature derating curve in the datasheet.

Package and board-level integration

Housed in the DO-214AC (SMA) package, the part is a surface-mount device with a standard footprint shared across the SMAJ series.
