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 Steering Diode/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.
