SS14-E3/61T

The SS14-E3/61T is a Schottky barrier rectifier diode manufactured by Vishay, designed for high-efficiency applications in power management and rectification. Here’s a detailed description of its key features and specifications:

Physical Characteristics:

• Package Type: The SS14 is typically housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) configuration. This package is compact, allowing for efficient use of space on printed circuit boards (PCBs).
• Dimensions: The dimensions of the DO-214AA package are approximately 5.2 mm x 6.0 mm x 1.5 mm, making it suitable for applications where space is a constraint.

Electrical Specifications:

• Reverse Voltage (V_R): The SS14 has a maximum reverse voltage rating of 40 volts, making it suitable for various low to moderate voltage applications.
• Forward Current (I_F): It can handle a continuous forward current of up to 1 ampere, which is adequate for many power supply and rectification tasks.
• Forward Voltage Drop (V_F): One of the key advantages of Schottky diodes is their low forward voltage drop. The SS14 typically exhibits a forward voltage drop of around 0.45 volts at a forward current of 1 ampere, which contributes to higher efficiency and lower heat generation.
• Reverse Recovery Time (t_rr): The SS14 features a very fast reverse recovery time, typically in the range of nanoseconds, which is beneficial for high-frequency applications.

Thermal Characteristics:

• Operating Temperature Range: The diode can operate effectively within a temperature range of -55°C to +150°C, making it suitable for a variety of environmental conditions.
• Junction-to-Case Thermal Resistance (RθJC): The thermal resistance is low, allowing for efficient heat dissipation during operation, which is critical for maintaining reliability and performance.

Applications:

The SS14-E3/61T is commonly used in:

• Power Supply Circuits: As a rectifier in AC to DC conversion applications.
• DC-DC Converters: In switching power supplies where efficiency is paramount.
• Solar Inverters: For rectifying the output from solar panels.
• Battery Chargers: To prevent reverse current flow and ensure efficient charging.

Additional Features:

• Low Leakage Current: The SS14 exhibits low reverse leakage current, which is advantageous for battery-operated devices and energy-efficient designs.
• RoHS Compliant: The device is compliant with the Restriction of Hazardous Substances (RoHS) directive, making it suitable for environmentally friendly applications.

In summary, the SS14-E3/61T from Vishay is a versatile Schottky diode that combines compact size, high efficiency, and robust performance, making it an excellent choice for a wide range of electronic applications.
