# SMBJ14A-HF (Component) ## Description 23.2VC Clamp 25.9A@10/1000us Ipp TVS DIODE SMB(DO-214AA) The SMBJ14A-HF is a unidirectional Transient Voltage Suppressor (TVS) diode designed to protect sensitive electronic circuits from high-voltage transient events such as ESD (electrostatic discharge), lightning-induced surges, and switching spikes. It is part of the SMBJ series, commonly used for general-purpose surge protection in compact surface-mount designs. It is housed in a DO-214AA (SMB) surface-mount package, making it suitable for automated PCB assembly and space-constrained applications. Key Features Working reverse standoff voltage (VRWM): 14 V Breakdown voltage: ~15.6 V to 17.2 V Clamping voltage: ~23.2 V at peak pulse current Peak pulse power: 600 W (10/1000 µs waveform) Peak pulse current: ~25.9 A Unidirectional TVS diode (single channel) Fast response to transient overvoltage events (nanosecond range) Low leakage current (typically ~1 µA) Operating temperature range: −55 °C to +150 °C Surface-mount DO-214AA (SMB) package RoHS compliant, HF (halogen-free) version (“-HF”) #CommonPartsLibrary #Diode ## Component Details - **Owner:** lcsc - **Created:** 11/4/2024 - **Last Updated:** 6/2/2026 - **Visibility:** Public - **Datasheet URL:** https://www.lcsc.com/datasheet/C2444165.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNeR1VeX1BUT1NbXjsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Part Type:** TVS - **License:** https://creativecommons.org/licenses/by/4.0/ - **Manufacturer Part Number:** SMBJ14A-HF - **Manufacturer Name:** Comchip(典琦) - **Package or Case Code:** SMB_L4.3-W3.6-LS5.4-RD - **JLCPCB Part Class:** Extended Part - **LCSC Part Number:** C2444165 - **Used in:** 86 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
