- DescriptionWhether you are designing a custom power supply or protecting a battery-powered IoT node, power efficiency and circuit safety are paramount. The SS14 is a highly reliable Surface Mount Schottky Barrier Rectifier designed to direct heavy currents seamlessly while minimizing power lost to heat.The Schottky Efficiency AdvantageStandard silicon diodes typically suffer from a 0.7V to 1.0V forward voltage drop. When pushing 1 Amp of current, that translates to a significant amount of wasted power and excess heat. The SS14 utilizes Schottky barrier technology to maintain a drastically lower forward voltage drop (typically under 0.5V at 1A). This ensures more power makes it to your load, prolonging battery life and keeping your printed circuit board cool.High-Frequency & FreewheelingBecause Schottky diodes do not have a standard P-N junction recovery time, they can switch incredibly fast. This makes the SS14 a premier choice for high-frequency Switch-Mode Power Supplies (SMPS) and DC-DC step-down converters. Furthermore, its 1A capacity makes it an excellent “flyback” or freewheeling diode, safely dissipating reverse voltage spikes caused by inductive loads like DC motors, solenoids, and mechanical relays.Robust SMA FootprintHoused in an industry-standard SMA (DO-214AC) surface-mount package, the SS14 offers a fantastic balance between compact sizing and thermal dissipation. The flat leads provide a large solderable surface area, making it robust against physical vibration and easy to handle during manual soldering or automated pick-and-place assembly.Key FeaturesUltra-Low Forward Voltage: Minimizes power dissipation, maximizing efficiency in low-voltage and battery-operated circuits.High Current Handling: Safely passes up to 1.0A of continuous current.Fast Switching: Near-zero reverse recovery time makes it ideal for high-frequency power management.Technical SpecificationsComponent Type: Schottky Barrier RectifierMaximum Repetitive Peak Reverse Voltage (VRRM): 40VMaximum RMS Voltage (VRMS): 28VMaximum Average Forward Current (IF(AV)): 1.0APeak Forward Surge Current (IFSM): 40A (for 8.3ms single half sine-wave)Maximum Forward Voltage Drop (VF): 0.50V at 1.0APackage Type: SMA / DO-214AC (Surface Mount)Top Marking Code: SS14Ideal ApplicationsReverse Polarity Protection: Shielding delicate microcontrollers and sensors from backward battery insertion.Power Management: Acting as the primary rectifier in DC-DC buck or boost converters.Inductive Load Protection: Serving as a freewheeling/flyback diode across motors and relays to clamp voltage spikes.Electronics Repair: Replacing blown SMA Schottky diodes in commercial power supplies and charging modules.
