# SS56 (Component) ## Description 60V Independent Type 700mV@5A 5A SMA(DO-214AC) Schottky Diodes ROHS The MDD SS56 is a Schottky barrier rectifier diode in a compact SMA (DO-214AC) surface-mount package, designed for high-efficiency power rectification in low-voltage, high-current applications such as DC-DC converters, power supplies, and polarity protection circuits. It uses a Schottky metal-semiconductor junction, which enables low forward voltage drop and fast switching performance, making it more efficient than standard PN junction diodes in switching power designs. Key Features Schottky technology for low forward voltage drop (~0.7 V at 5 A typical) Maximum repetitive reverse voltage: 60 V Average forward current: 5 A High surge current capability: up to 125 A (8.3 ms half-sine) Low power loss / high efficiency operation Fast switching (no significant reverse recovery delay) Low reverse leakage current (~1 mA at 60 V typical) High junction temperature rating: up to ~150°C Surface-mount SMA (DO-214AC) package for compact PCB design Typical Applications DC-DC converters (buck / boost converters) Power rectification in SMPS (switch-mode power supplies) Reverse polarity protection Freewheeling / flyback diode in inductive loads Battery-powered and portable electronics High-efficiency power management circuits #CommonPartsLibrary #Diode ## Component Details - **Owner:** lcsc - **Created:** 10/15/2024 - **Last Updated:** 5/28/2026 - **Visibility:** Public - **JLCPCB Part Class:** Extended Part - **Manufacturer Part Number:** SS56 - **Datasheet URL:** https://www.lcsc.com/datasheet/C65009.pdf?spm=wm.sxq.inf.ggs___wm.ssy.bg.0.xh&lcsc_vid=T1kIXgFeT1NaU1RXQFBbUlUHT1cKU1NXFVBeX1VSTlAxVlNRTlhaXlxfQlZWUjsOAxUeFF5JWBYZEEoKFBINSQcJGk4dAgUUFAk%3D - **Diode Type:** Schottky Diode - **License:** https://creativecommons.org/licenses/by/4.0/ - **Part Type:** Schottky Barrier Diodes (SBD) - **Package or Case Code:** SMC_L6.9-W5.9-LS7.9-R-RD - **LCSC Part Number:** C65009 - **Manufacturer Name:** MDD(Microdiode Semiconductor) - **Forward Voltage:** 0.55V - **Reverse Voltage:** 60V - **Used in:** 269 projects ## Distributor Pricing (qty 1) *Pricing shown for quantity 1.
