SS14-M3/61T

The SS14-M3/61T is a Schottky barrier rectifier diode manufactured by Vishay, designed for high-efficiency applications in power management and rectification circuits. 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 DO-214AA package generally measures approximately 5.2 mm in length, 3.5 mm in width, and 1.5 mm in height, making it suitable for applications where space is a constraint.

Electrical Specifications:

• Reverse Voltage (VR): The SS14 is rated for a maximum reverse voltage of 40 volts, making it suitable for a variety of low to moderate voltage applications.
• Forward Current (IF): It can handle a continuous forward current of up to 1 ampere, which is adequate for many consumer electronics and power supply circuits.
• Forward Voltage Drop (VF): One of the key advantages of Schottky diodes is their low forward voltage drop. The SS14 typically has 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 in circuits.
• Reverse Recovery Time (trr): The SS14 features a very fast reverse recovery time, which is characteristic of Schottky diodes. This allows for rapid switching applications, reducing losses during operation.

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 wide range of environmental conditions.
• Thermal Resistance: The thermal resistance junction-to-ambient is low, which helps in dissipating heat efficiently during operation.

Applications:

The SS14-M3/61T is commonly used in:

• Power Supply Circuits: As a rectifier in AC to DC conversion.
• Switching Power Supplies: For efficient power management.
• Solar Inverters: To improve efficiency in renewable energy applications.
• Battery Chargers: To prevent reverse current flow and enhance charging efficiency.
• LED Drivers: In circuits where low forward voltage drop is critical.

Additional Features:

• Low Leakage Current: The SS14 exhibits low reverse leakage current, which is beneficial for battery-operated devices, as it helps in conserving battery life.
• RoHS Compliance: The device is compliant with RoHS (Restriction of Hazardous Substances) standards, ensuring it is environmentally friendly and safe for use in consumer electronics.

In summary, the SS14-M3/61T from Vishay is a versatile Schottky diode that combines compact size, high efficiency, and robust performance, making it an excellent choice for a variety of electronic applications.
