Additional Details:

The SMAJ36CA-E3/61T features a standoff voltage of 36 V and a breakdown voltage between 40 V and 44.4 V. It has a peak pulse power dissipation of 400 W at 10/1000 μs waveform. The operating junction temperature range is -55 °C to +150 °C. The device is bidirectional, meaning it provides protection against both positive and negative voltage transients. The package is a DO-214AC (SMA). The clamping voltage at peak pulse current is 58.1 V. It is designed to meet various industry standards for surge protection, ensuring reliable performance in harsh environments. Its fast response time is critical for protecting sensitive components from fast transient events. This TVS diode effectively shunts transient energy away from protected circuits, safeguarding them from damage.
