About this product
The SMBJ20CA is a bidirectional transient voltage suppression (TVS) diode in an SMB package. It clamps voltage spikes and protects sensitive circuits from ESD and transient surges. The CA suffix indicates bidirectional operation, which suits AC or signal lines that see voltage of either polarity.

Frequently asked questions
What is the price of SMBJ20CA 20V Bidirectional ESD TVS Protection Diode, SMB in Egypt?
SMBJ20CA 20V Bidirectional ESD TVS Protection Diode, SMB currently costs 5.7 EGP in Egypt.
Where can I buy SMBJ20CA 20V Bidirectional ESD TVS Protection Diode, SMB in Egypt?
SMBJ20CA 20V Bidirectional ESD TVS Protection Diode, SMB is available from UGE. Compare the offers above to find the best price.
Where should I place it in a circuit?
Connect it across the line you want to protect, between the signal or power line and ground, and place it as close as possible to the connector or entry point. Keep the connection to ground short.
Do I need the bidirectional version for a DC supply line?
Not always. A unidirectional TVS is common on DC rails with a fixed polarity. The bidirectional SMBJ20CA suits AC lines or signal lines that swing both ways. In either case, the 20 V standoff voltage must be above the normal operating voltage of the line.
