SDC15

TVS Diode Array for ESD Protection

of 12V Data and Power Lines

Description

Features

Circuit Diagram

Schematic & PIN Configuration

Revision 12/15/04

The SDC15 transient voltage suppressor (TVS) is

designed to protect components which are connected

to data and transmission lines from voltage surges

caused by electrostatic discharge (ESD)

(ESD)

(ESD), electrical fast

transients (EFT)

(EFT)

(EFT) , and lightning

lightning.

TVS diodes are characterized by their high surge

capability, low operating and clamping voltages, and

fast response time. This makes them ideal for use as

board level protection of sensitive semiconductor

components. The dual-junction common-cathode

design allows the user to protect one data or power

line operating at ±12 volts. The low profile SOT23

package allows flexibility in the design of “crowded”

circuit boards.

The SDC15 TVS will meet the surge requirements of

IEC 61000-4-2 (Formerly IEC 801-2), Level 4, “Human

Body Model” for air and contact discharge.
