The STTH102 is a silicon, surface mount ultrafast power rectifier offering up to 1A average rectified current and up to 1.3kV repetitive peak reverse voltage. Combining fast switching speed with electrically-efficient rectification makes this rectifier ideal for power factor correction and power conversion applications.

Applications for the STTH102 include telecom power supplies, computer power supplies, 28V aircraft power circuits, and electronic ballasts. This rectifier can be used in electronic power systems, such as AC-DC, DC-DC and DC-AC power conversion systems. It can also be used in solar systems, LED lamps, and other renewable energy devices. As an ultrafast power rectifier, the STTH102 can provide high frequency switching speeds that can be beneficial for advanced power systems.

The STTH102 has an industry-standard style featuring a low-profile, plastic surface mount package. The package size measures 3.2*3.3mm and weighs only .079g. The STTH102 is compatible with any automated surface mount assembly (SMT) process and can be soldered and assembled easily. Its construction meets the requirements of the lead-free RoHS directive.

The working principle for the STTH102 rectifier is based on the PN junction diode. In this case, electrons flow from the emitter to the collector, allowing the rectifier to pass only the forward bias voltage. If a reverse bias voltage is applied, the current flow will be restricted, preventing the circuit from becoming damaged. When the forward bias voltage is applied, the current flow will be significantly higher, allowing the rectifier to pass higher current levels.

In addition to its standard rectifying capabilities, the STTH102 also offers low efficiency losses, excellent reverse recovery time and low temperature rise. This provides the circuits with a significantly reduced heat load, allowing them to operate more efficiently. Furthermore, due to its ultrafast switching capability, it can provide a higher frequency operation, giving power systems more flexibility and control.

The STTH102 rectifier is a reliable and efficient power device designed for a variety of high power applications. It has a low-profile, surface mount package with a small size and weight, making it compatible with any automated manufacturing process. It has a high current-carrying capacity and offers low power losses, excellent reverse recovery time and low temperature rise, making it an ideal choice for many power systems.
