Bourns announces the CDSOD323-TxxSC-Q Series, an automotive‑grade transient voltage suppressor (TVS) diode family designed to protect a single signal line from electrostatic discharge (ESD) and surge events in space‑constrained designs. The series combines up to ±30 kV ESD protection with a compact SOD‑323 surface‑mount package, supporting high‑reliability interface protection across consumer and automotive electronics.

The CDSOD323-TxxSC-Q Series delivers bidirectional protection in a single device, reducing component count and board space in designs where interface density and immunity requirements compete for layout real estate. The series maintains compliance with common ESD, EFT, and surge standards without requiring additional external protection components.

“This series provides designers with a compact TVS option that aligns with current miniaturization trends while maintaining automotive qualification and standardized immunity performance,” - Rollin Roos, Product Line Manager, Semiconductor Products at Bourns.
