BIDIRECTIONAL 1 Bourns offers Transient Voltage Suppressor Diodes for surge and ESD protection applications in SOD323 package size format. The Transient Voltage Suppressor Diode series offers a choice of voltage types ranging from 12 V to 24 V in a 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 will assist in meeting IEC 61000-4-5 (Surge) requirements. 2 Absolute Maximum Ratings (@ TA = 25 °C Unless Otherwise Noted) CDSOD323Parameter Symbol T12C-DSL T24C-DSL Unit Peak Pulse Current (tp = 8/20 µs) IPPM 11 6 A Peak Pulse Power (tp = 8/20 µs) PPP 350 W TJ -55 to +150 ºC TSTG -55 to +150 ºC ESD ESD ±8 ±30 kV kV ESD ESD ±15 ±30 kV kV Operating Temperature Storage Temperature ESD Protection (per IEC 61000-4-2) Contact Discharge Minimum Maximum Air Discharge Minimum Maximum Electrical & Thermal Characteristics (@ TA = 25 °C Unless Otherwise Noted) CDSOD323Parameter Symbol T12C-DSL T24C-DSL Unit Min.
