The SDT06S60 is a single-channel ultra-fast recovery diode (UFRD) that is part of the Vishay Siliconix family of discrete semiconductors. It is designed to meet the high-frequency needs of switching power supplies, voltage multipliers, and other high-frequency power conversion applications that involve the conversion of energy from one form to another.

These high-speed UFRDs provide higher dynamic levels and higher frequency operation than standard fast recovery diodes, with a maximum recommended operating frequency of up to 1 MHz. They also feature low forward voltage, low reverse recovery current, and soft recovery characteristics.

The SDT06S60 is designed in a standard TO-247 package, allowing for easy integration into existing power paths and easy thermal and electrical connection. It also has a variety of pin definitions for different application needs.

The SDT06S60 has a very short reverse recovery time of 250 ns, along with a moderate reverse current increase at temperatures of up to 150°C. In addition, it typically has a low forward voltage drop of 1.25 V.

The primary application fields of SDT06S60 include AC-DC rectifiers, DC-DC converters, high-frequency resonant converters and inversion circuits. All these circuits convert electrical energy from one form to another, and do so by utilizing fast recovery diodes for their functionality and benefits.

This diode is also used in ultra-low EMI switching power supplies, DC-AC inverters, motor drives, and high-end power supplies, as these circuits require fast switching between a conductive state and a non-conductive state.

The working principle of the SDT06S60 UFRD is based on the electrical property of the p-n junction, known as the reverse recovery characteristic. During forward operation, the device behaves as a conventional diode, with current passing through it when it is properly biased. When the bias is reversed, the device enters the reverse recovery state, in which the stored energy is dissipated as the junction capacitance is driven to zero. Therefore, the reverse current returns to its original value much faster than with a conventional diode, allowing faster switching between conductive and non-conductive states.

The SDT06S60 is also an excellent choice for energy conservation applications. Since it can switch between on and off states faster than other diode solutions, it helps reduce power loss through related components. This makes it an ideal choice for applications that need high-performance power conversion solutions with reduced power dissipation.

In summary, the SDT06S60 is a high-performance single-channel ultra-fast recovery diode, part of the Vishay Siliconix family of discrete semiconductor products. It offers high-speed switching operation with a reverse recovery time of 250 ns and a low forward voltage drop of 1.25 V, and is suitable for a wide variety of applications including AC-DC rectifiers, DC-DC converters, and energy conservation applications. Thanks to its standard TO-247 package, it is an easy-to-integrate solution for existing power paths.
