About this product
SMBJ18CA is a 600W bidirectional TVS (transient voltage suppression) diode in an SMB (DO-214AA) surface-mount package, with an 18V standoff voltage. It clamps fast transients such as switching spikes, lightning-induced surges and ESD events to a safe level, protecting I/O lines and VCC rails in phones, portable devices and power supplies.

Frequently asked questions
What is the price of SMBJ18CA TVS Diode 600W 18V Bidirectional SMB (DO-214AA) in Egypt?

Is SMBJ18CA unidirectional or bidirectional?
It is bidirectional, as indicated by the CA suffix. It clamps voltage spikes in both polarities, so it suits AC lines or signals that swing above and below ground. For a DC line that stays positive, a unidirectional part (SMBJ18A without CA) is commonly used.
How do I choose the right standoff voltage?
The 18V standoff should be higher than the maximum normal operating voltage of the line you protect, so the diode stays inactive during normal operation. Place it between the line and ground, close to the input connector.
