Bourns CDSOD323-T05C 5V Bidirectional TVS Diode (350W, SOD-323)

Protect sensitive 5V logic lines and bidirectional signal buses against electrostatic discharge (ESD) and high-energy surge transients with the Bourns CDSOD323-T05C TVS diode. Unlike standard unidirectional diodes designed solely for DC power rails, this specialized bidirectional TVS diode handles AC signal swings and bipolar voltage transients that cross above and below ground. This makes it an ideal choice for protecting differential data buses such as CAN bus, RS-485, I2C, and analog audio inputs in industrial automation, automotive electronics, and custom robotics.

Featuring a 5V reverse standoff voltage ($V_{wm}$) and a peak pulse power rating of up to 350 Watts ($8/20\,\mu\text{s}$ impulse), the CDSOD323-T05C provides heavy-duty surge protection while remaining completely passive during normal circuit operation. Housed in the compact SOD-323 surface-mount package, it provides a robust defense against lethal static shocks and inductive kickbacks directly at the connector or interface boundary.

Key Features:

• Bidirectional Surge Protection: Designed specifically for signal lines where voltages fluctuate above and below 0V (CAN, RS-485, AC/audio lines).

• 5V Working Voltage ($V_{wm}$): Perfectly matched for standard 5V digital logic buses, sensor lines, and communications interfaces.

• 350W Peak Pulse Power: Easily absorbs high-energy transient voltage surges and electrostatic discharges (compliant with IEC 61000-4-2 Level 4).

• Compact SOD-323 Package: Takes up minimal PCB footprint while providing superior surge handling over tiny ESD-only diodes.
