# SMBJ6.8CA (Component) ## Description The SMBJ6.8CA is a bidirectional Transient Voltage Suppression (TVS) diode designed to protect sensitive electronic circuits from voltage transients caused by electrostatic discharge, lightning-induced surges, inductive load switching, and other transient events. It is commonly used in power supplies, communication interfaces, industrial control systems, automotive electronics, and consumer devices requiring robust overvoltage protection. The device utilizes avalanche breakdown technology to rapidly clamp transient voltages to safe levels, helping prevent damage to downstream components. Its bidirectional configuration makes it suitable for protecting AC lines and signal lines where voltage polarity may reverse. The SMB package provides a compact surface-mount solution with high surge-handling capability and excellent reliability for demanding environments. Features Bidirectional transient voltage suppression diode Fast response time to transient events High peak pulse power dissipation capability Low incremental surge resistance Excellent clamping performance Surface-mount SMB package Protection against ESD and lightning-induced surges Suitable for AC and bidirectional signal line protection RoHS-compliant and halogen-free options available from various manufacturers High reliability and long operational life Electrical Characteristics Reverse standoff voltage optimized for low-voltage applications Avalanche breakdown protection mechanism High peak surge current capability Low leakage current during normal operation Bidirectional voltage clamping characteristics Designed for transient suppression in accordance with industry surge standards Applications Power input protection Communication interfaces Industrial automation equipment Automotive electronic modules Consumer electronics Data and signal line protection Telecom equipment Embedded control systems Sensor interface protection Package Information Package Type: SMB (DO-214AA) Surface-mount technology Compact footprint for PCB integration Suitable for automated assembly processes #commonpartslibrary #semiconductor #tvsdiode #esdprotection #surgeprotection #circuitprotection #transientvoltagesuppressor #powerprotection #electronics #surfaceMountDevice #automotiveelectronics #industrialelectronics ## Component Details - **Owner:** lcsc - **Created:** 10/15/2024 - **Last Updated:** 6/2/2026 - **Visibility:** Public - **Part Type:** Pre-ordered Products - **Manufacturer Name:** SHIKUES(时科) - **JLCPCB Part Class:** Extended Part - **Manufacturer Part Number:** SMBJ6.8CA - **Diode Type:** Unidirectional TVS Diode - **Package or Case Code:** SMB_L4.6-W3.6-LS5.3-BI - **Forward Voltage:** 1V - **Datasheet URL:** https://www.lcsc.com/datasheet/C962728.pdf?spm=wm.sxq.inf.ggs&utm_source=octopart&lcsc_vid=FAAIAQFTEVZYVVwCT1ldXwEFRwRWAlRXEVRbUQEFFgAxVlNeR1VeUFxTTlZYVTsOAxUeFF5JWA4NEwsWFhMaSQcJGk4%3D - **Reverse Voltage:** 6.8V - **LCSC Part Number:** C962728 - **Used in:** 84 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
