# SS14 (Component) ## Description 40V Independent Type 1A 550mV@1A SMA(DO-214AC) The SS14 is a surface-mount Schottky Barrier Rectifier Diode commonly used for power management, reverse-polarity protection, DC/DC converters, freewheeling circuits, and high-frequency switching applications. It is valued for its low forward voltage drop, fast switching speed, and high efficiency compared to standard silicon rectifier diodes. Key Features Schottky barrier rectifier Maximum repetitive reverse voltage (VRRM): 40 V Average forward current (IF): 1 A Low forward voltage drop: typically around 0.5 V at 1 A High surge current capability: up to 30–40 A (non-repetitive surge) Fast switching performance Low power loss and high efficiency Guard ring protection for improved overvoltage reliability Surface-mount SMA (DO-214AC) package Operating junction temperature up to 150°C RoHS-compliant versions available Typical Applications DC/DC converters Switching power supplies (SMPS) Reverse-polarity protection circuits Freewheeling and flyback paths Battery-powered devices High-frequency inverters General low-voltage power rectification #CommonPartsLibrary # ## Component Details - **Owner:** lcsc - **Created:** 10/10/2024 - **Last Updated:** 6/1/2026 - **Visibility:** Public - **Forward Voltage:** 0.45V-0.50V - **Max Reverse Voltage:** 40V - **Package or Case Code:** SMA_L4.3-W2.7-LS5.1-RD - **Manufacturer Part Number:** SS14 - **License:** https://creativecommons.org/licenses/by/4.0/ - **Datasheet URL:** https://www.lcsc.com/datasheet/C2766061.pdf?spm=wm.sxq.inf.ggs&lcsc_vid=FlkNBAIDRQULVABfFAVZBgZVFVZYBgZSQ1NeBVIFQlExVlNeR1JfUFRQQFlfUzsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **LCSC Part Number:** C2766061 - **Diode Type:** Schottky Diode - **Manufacturer Name:** WPMtek(维攀) - **JLCPCB Part Class:** Extended Part - **Part Type:** Schottky Barrier Diodes (SBD) - **Used in:** 192 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
