** Bourns follows the prevailing defi nition of “halogen free” in the industry. Bourns considers a product to be “halogen free” if (a) the Bromine (Br ) content is 900 ppm or less;
(b) the Chlorine ( Cl ) content is 900 ppm or less; and (c) the total Bromine (Br) and Chlorine ( Cl ) content is 1500 ppm or less.
Specifi cations are subject to change without notice.
Customers should verify actual device performance in their specifi c applications.
Note: The electrical specifi cations apply in both polarities.
General Information
The markets of portable communications and telecom equipment are challenging the
semiconductor industry to develop increasingly smaller electronic components for high-
speed communication rates.
Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection
applications in SOD323 package size format. The Transient Voltage Suppressor Diode
series offers a choice of voltage types ranging from 12 V to 24 V in a bidirectional
confi guration. Bourns® Chip Diodes conform to JEDEC standards, are easy to handle
on standard pick and place equipment and their fl at confi guration minimizes roll away.
The Bourns® device will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and will
assist in meeting IEC 61000-4-5 (Surge) requirements.
