Level 4) ■ IEC 61000-4-4 EFT ■ IEC 61000-4-5 Surge - Peak Pulse Power: 600 watts - Typical temperature coefficient: ΔVBR = 0.1 % x VBR @ 25 °C x ΔT ## POURNS ~~Ei~~ **P6SMB Transient Voltage Suppressor Diode Series** ## ~~**General Information**~~ 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 Diodes for surge and ESD protection applications, in compact chip package DO-214AA (SMB) size format. The Transient Voltage Suppressor series offers a choice of Breakdown Voltages from 6.8 V up to 550 V. Typical fast response times are less than 1.0 picosecond for unidirectional devices and less than 5.0 picoseconds for bidirectional devices from 0 V to Minimum Breakdown Voltage. ## ~~**Additional Information**~~ Click these links for more information: PRODUCT TECHNICAL INVENTORY SAMPLES CONTACT SELECTOR LIBRARY Bourns[®] Chip Diodes conform to JEDEC standards, are easy to handle with standard pick and place equipment and the flat configuration minimizes roll away. ## ~~**Maximum Characteristics (@ T**~~ **A** ~~**= 25 °C Unless Otherwise Noted)**~~ |**Parameter**|**Parameter**|**Symbol**|**Value**|**Unit**| |---|---|---|---|---| |Peak Pulse Power Dissipation (TP = 1 ms)(Note 1,2)||PPK|600|Watts| |Peak Forward Surge Current
