General Information

Electrical Characteristics (@ TA= 25 °C Unless Otherwise Noted)

Thermal Characteristics (@ TA= 25 °C Unless Otherwise Noted)

The markets of portable communications, computing and video equipment are challenging the

semiconductor industry to develop increasingly smaller electronic components.

Bourns offers Transient Voltage Suppressor Array combination diodes for surge and ESD protection

applications in an 8 Lead Narrow Body SOIC package size format. Bourns Chip Diodes conform to

JEDEC standards, are easy to handle on standard pick and place equipment and their flat

configuration minimizes roll away.

The Bourns device®will meet IEC 61000-4-2 (ESD), IEC 61000-4-4 (EFT) and IEC 61000-4-5

(Surge) requirements.
