Frequently Asked Questions
What is the standoff voltage and peak pulse power rating of the SMAJ13CA?
The SMAJ13CA has a standoff voltage of 13 V and a peak pulse power rating of 400 W at a 10/1000 µs waveform. Its breakdown voltage ranges from 14.4 V to 15.9 V, and it clamps transient events to a maximum of 21.5 V, protecting downstream circuits effectively.
Can the SMAJ13CA suppress transients in both directions on a signal line?
Yes, the SMAJ13CA is a bidirectional (CA suffix) TVS diode, meaning it clamps voltage spikes in both polarities. This makes it ideal for protecting AC signal lines, RS-485 buses, and CAN interfaces where transients can occur in either direction. Its maximum clamping voltage is 21.5 V at test current conditions.
Which package does the SMAJ13CA use, and how does it affect PCB layout?
The SMAJ13CA is housed in a DO-214AC (SMA) surface mount package, which measures approximately 4.4 mm × 2.6 mm and sits low on the PCB. The SMA package supports automated SMT assembly, offers a compact 2-pin footprint, and its low parasitic inductance enables fast transient clamping response times in the picosecond to nanosecond range.
