Bourns Announces CDSOD323 TxxSC Q Automotive Grade TVS Diodes for High ESD Protection in SOD 323 Packages
24 June 2026 Bourns has announced the CDSOD323-TxxSC-Q Series, an automotiveâgrade transient voltage suppressor (TVS) diode family designed to protect a single signal line from electrostatic discharge (ESD) and surge events in spaceâconstrained designs.
The companys says the series combines up to ±30 kV ESD protection with a compact SODâ323 surfaceâmount package, supporting highâreliability interface protection across consumer and automotive electronics.
The CDSOD323-TxxSC-Q Series can deliver 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.
