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® 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 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 µs) PPP 500 W Bidirectional Peak Pulse Power (tp = 8/20 µs) PPP 400 W TL -55 to +150 ºC TSTG -55 to +150 ºC ESD ±8 ±30 ±15 ±30 Operating Temperature Storage Temperature ESD Protection (per IEC 61000-4-2) Contact - Min.
