# 1N4148SOD-123 (Component) ## Description DIODE GP 75V 150mA SOD-123 The 1N4148 (SOD-123) is a silicon epitaxial planar switching diode designed for fast switching applications. It is widely used in surface-mount designs as the SMD version of the classic 1N4148 (DO-35 through-hole type). It is mainly used for low-current, high-speed switching circuits, such as signal clamping, protection, logic circuits, and general rectification in small electronics. Key Features Fast switching speed (reverse recovery time typically ≤ 4 ns) Reverse voltage up to 100 V (peak) Average forward current: ~150 mA Compact SOD-123 surface-mount package (2-pin SMD) Low power dissipation (~400–500 mW depending on manufacturer) Low reverse leakage current (very small, µA or less) Low junction capacitance (~2–4 pF typical) for high-speed operation Wide operating temperature range: -55°C to +150°C Suitable for automatic PCB assembly (SMT reflow compatible) #CommonPartsLibrary #Diode ## Component Details - **Owner:** lcsc - **Created:** 11/5/2024 - **Last Updated:** 6/1/2026 - **Visibility:** Public - **Manufacturer Name:** JKSEMI(金开盛) - **Manufacturer Part Number:** 1N4148SOD-123 - **LCSC Part Number:** C2972760 - **Datasheet URL:** https://www.lcsc.com/datasheet/C2972760.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNeR1JcUldURVBZUTsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Part Type:** Switching Diode - **Package or Case Code:** SOD-123_L2.6-W1.6-LS3.5-RD - **License:** https://creativecommons.org/licenses/by/4.0/ - **JLCPCB Part Class:** Extended Part - **Used in:** 852 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
