About this product
SMBJ6.8CA is a 600 W bidirectional TVS diode in the SMB (DO-214AA) surface-mount package. It clamps transients of both polarities, making it suited to AC lines and signals that swing above and below ground. Its 6.8 V stand-off voltage targets low-voltage circuits.

Frequently asked questions
When should I choose a bidirectional TVS over a unidirectional one?
Choose bidirectional when the line swings both positive and negative relative to ground, such as AC signals or differential lines. For fixed DC rails, a unidirectional type is usually sufficient.
Is the orientation important when wiring it?
No. Bidirectional TVS diodes have no polarity, so either terminal can be connected to the protected line and the other to ground.
