UNIDIRECTIONAL 1 BIDIRECTIONAL 1 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. 2 2 Electrical & Thermal Characteristics (@ TA = 25 °C Unless Otherwise Noted) Parameter Symbol Value Unit PPP 350 W TJ -55 ˚C to 150 ˚C ˚C TSTG -55 ˚C to 150 ˚C ˚C Peak Pulse Power (tp = 8/20 µs) Operating Temperature Storage Temperature CDSOD323Parameter Symbol UniT03 BiT03C UniT05 BiT05C UniT08 BiT08C UniT12 BiT12C Unit Min.
