This new generation TVS is designed to protect sensitive electronics from the damage due to ESD. The combination of small size and high ESD surge capability makes it ideal for use in portable applications such as cellular phones, digital cameras, and MP3 players The DESD12V0S1BL may be used to meet the ESD immunity requirements of IEC 61000-4-2, Level 4 and IEC 61000-4-5. The TVS diodes provide effective suppression of ESD voltages: ±30kV (air discharge) and ±30kV (contact discharge).
