400 W peak pulse, 6.5 V standoff — unidirectional TVS in DO-214AC
The Diodes Incorporated SMAJ6.5A-13 is a Zener-type unidirectional TVS diode rated for 400 W peak pulse power dissipation (10/1000 µs waveform). Housed in the standard DO-214AC (SMA) surface-mount package, the part is intended for general-purpose circuit protection on low-voltage DC buses, I/O lines, and power supply inputs where a single unidirectional clamping element is sufficient.
Clamping voltage and peak current — the transient protection envelope
The minimum breakdown voltage of 7.22 V at 1 mA ensures the device enters avalanche before the protected rail exceeds its abs-max rating. Power line protection is not claimed (No per), meaning this TVS is intended for signal and low-power DC rail protection rather than AC mains or high-energy surge paths where a higher-energy MOV or GDT would be specified.
Active production, standard DO-214AC footprint
The DO-214AC package is a widely used SMA footprint shared across the SMAJ series from multiple manufacturers. Board layout is standard: the cathode tab is the die attach pad, and the anode is the opposite end termination.
