General Information
Electrical & 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 diodes for surge and ESD
protection applications, in SOD323 package size format. The Transient Voltage
Supressor Array series offers a choice of voltage types ranging from 3 V to 24 V in a
unidirectional or bidirectional configuration. 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.
Notes:
1. Part numbers with suffix “C” indicate bidirectional device, i.e. CDSOD323-T05C.
2. For bidirectional devices only, the electrical specifications apply in both directions.
