UNIDIRECTIONAL 1 BIDIRECTIONAL 1 Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection applications in SOD323 package size format. The Transient Voltage Suppressor series offers a choice of voltage types ranging from 3 V to 36 V in a unidirectional or bidirectional configuration. Bourns(R) 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(R) device meets 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 Unidirectional Peak Pulse Power (tp = 8/20 s) PPP 500 W Bidirectional Peak Pulse Power (tp = 8/20 s) PPP 400 W TL -55 to +150 C TSTG -55 to +150 C ESD 8 30 15 30 Operating Temperature Storage Temperature ESD Protection (per IEC 61000-4-2) Contact - Min.
