SMBJ5.0A Basic Circuit

Build a basic SMBJ5.0A circuit with labeled pins, component values and connection guidance.

SMBJ5.0A in a circuit

TVS across the input, with coordinated upstream protection.

5 V source through fuse to protected load, banded TVS cathode at rail and anode to ground.
Conceptual topology; choose fuse, source impedance and protector from actual surge requirements.

Connect it, step by step

Follow the component values and pin connections

Protected node

Connect the banded cathode to the protected positive rail.

Short return

Connect the anode directly to the local return.

Coordinate protection

The TVS does not replace a fuse for sustained faults.
