SDC15 TVS Diode Array for ESD Protection of 12V Data and Power Lines PROTECTION PRODUCTSPROTECTION PRODUCTS Features Description The SDC15 transient voltage suppressor (TVS) is 300 watts peak pulse power (t = 8/20s) p designed to protect components which are connected 40 watts peak pulse power (t = 10/1000s) p to data and transmission lines from voltage surges Transient protection for data and power lines to caused by electrostatic discharge (ESD)(ESD)(ESD), electrical fast (ESD)(ESD) IEC 61000-4-2 (ESD) 15kV (air), 8kV (contact) (EFT)(EFT) lightninglightning transients (EFT)(EFT) , and (EFT) lightninglightning.lightning IEC 61000-4-4 (EFT) 40A (5/50ns) TVS diodes are characterized by their high surge IEC 61000-4-5 (Lightning) 12A (1.2/50s) capability, low operating and clamping voltages, and Protects one bidirectional line fast response time. This makes them ideal for use as Low clamping voltage board level protection of sensitive semiconductor Low leakage current components. The dual-junction common-cathode High surge capability design allows the user to protect one data or power Solid-state silicon avalanche technology line operating at 12 volts. The low profile SOT23 package allows flexibility in the design of crowded Mechanical Characteristics circuit boards. JEDEC SOT23 package The SDC15 TVS will meet the surge requirements of Molding compound flammability rating: UL 94V-0 IEC 61000-4-2 (Formerly IEC 801-2), Level 4, Human Marking : DC15 Body Model for air and contact discharge.
