About this product
SMBJ1A is listed as a 600W unidirectional TVS diode in the SMB (DO-214AA) surface-mount package. It is used to clamp fast transient voltages such as ESD and switching surges on I/O lines and power rails. Confirm the standoff voltage on the manufacturer datasheet before selecting it for a circuit.

Frequently asked questions
What is the standoff voltage of this part?
The listing does not state it, and the standard SMBJ series does not include a 1V device, so confirm the exact part number and standoff voltage on the manufacturer datasheet before use.
How should I connect this TVS diode?
Connect it in parallel with the protected line, with the cathode (marked band) toward the positive line and the anode toward ground.
