Additional Details:

The SMAJ6.8A features a standoff voltage of 6.8 V, and a breakdown voltage between 7.56 V and 8.36 V. The peak pulse power dissipation is 400 W at a 10/1000 μs waveform. The operating junction temperature range is -55 °C to +150 °C. The clamping voltage at peak pulse current is 12.3 V. The package is a DO-214AC (SMA). The device is unidirectional, meaning it provides protection against positive voltage transients. The fast response time is crucial for protecting sensitive components. The low incremental surge resistance ensures efficient clamping of transient voltages. By diverting excess voltage away from sensitive components, it prevents damage and ensures the continuous operation of the protected equipment.
