Additional Details:

The SMAJ6.0A-E3/61T features a standoff voltage of 6.0 V, with a breakdown voltage ranging from 6.67 V to 7.37 V. It has a peak pulse power dissipation of 400 W at a 10/1000 μs waveform. The operating junction temperature range is -55 °C to +150 °C. The device is unidirectional, meaning it provides protection against positive voltage transients. The package is a DO-214AC (SMA). Clamping voltage at peak pulse current is 11.2 V. The low incremental surge resistance ensures efficient clamping of transient voltages. The fast response time is crucial for protecting sensitive components from fast transient events. It is compliant with RoHS standards, restricting the use of certain hazardous substances. By diverting excess voltage away from sensitive components, it prevents damage and ensures continuous operation of the protected equipment.
