Applications
The SMAJ13CAE3/TR13 bidirectional TVS diode provides transient overvoltage protection on AC signal lines, data communication interfaces, and power supply inputs where both polarities of voltage spikes can occur. Its 500 W peak power handling and 21.5 V maximum clamping voltage make it suitable for protecting RS-485, CAN bus, and analog signal lines in industrial equipment from ESD and lightning-induced surges. The SMA package allows placement directly at board-level input connectors for effective line protection.

Frequently Asked Questions
For RS-485 bus protection, how does the SMAJ13CAE3/TR13 clamp transient voltages on signal lines?
The SMAJ13CAE3/TR13 clamps transient voltages to a maximum of 21.5 V during a surge event on an RS-485 line, protecting downstream transceivers rated below that level. Its bidirectional configuration handles both positive and negative transients, and its 500 W peak pulse power dissipation absorbs surge energy from ESD events and conducted transients.
What is the breakdown voltage range of the SMAJ13CAE3/TR13, and how is it selected for 12 V system protection?
The SMAJ13CAE3/TR13 has a breakdown voltage ranging from 14.4 V to 15.9 V with a nominal of 15.15 V, making it appropriate for protecting 12 V bus circuits. At 12 V nominal operation, the standoff voltage of 13 V ensures the TVS diode remains non-conducting during normal operation while triggering on transient overvoltages above 14.4 V.
Can the SMAJ13CAE3/TR13 be used on both AC and DC supply lines given its bidirectional design?
Yes, the SMAJ13CAE3/TR13 is rated as a bidirectional TVS diode capable of clamping transient voltages on AC signal and supply lines in both positive and negative directions. With 500 W peak pulse power and a 21.5 V maximum clamping voltage, it is suitable for protecting 12 V AC and DC circuits including motor drive signals and sensor supply rails.
How does the SMA package of the SMAJ13CAE3/TR13 support high-volume automated PCB assembly?
The SMAJ13CAE3/TR13 uses a 2-pin SMA surface-mount package supplied in tape-and-reel format (TR13), directly compatible with standard automated pick-and-place equipment. The moulded non-polarized package simplifies assembly orientation rules since both polarities are handled by the bidirectional TVS, reducing placement errors in high-volume production.
