General Information
Portable communications, computing and video equipment manufacturers are challenging
the semiconductor industry to develop increasingly smaller electronic components.
Bourns oers Transient Voltage Suppressor Array diodes for surge and ESD protection
applications, in compact chip package SOT23 size format. The TransientVoltage Supressor
Array series oers a choice of voltage types ranging from 3 V to 36 V. Bourns® Chip Diodes
conform to JEDEC standards, are easy to handle on standard pick and place equipment
and their at conguration 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.
