Diodes - Rectifiers - Single

SK18-TP is an ultra-fast, ultra-sensitive, low power, low forward voltage drop during turn-on, Self-aligned rectifier diode. It features a double-diffused planar structure and is available in the SOT-3 plastic package. Its robust package and excellent reverse leakage characteristics make it perfect for portable applications, such as consumer electronics, and power supply management. As compared to standard rectifiers, the SK18-TP takes less power and provides a faster response time.

Application Field

SK18-TP is a high-speed, low-power rectifier ideal for portable applications, including consumer electronics and power supply management. It is effectively immune to voltage transients and is often used in applications such as frequency converters, remote sensing schemes, SCR protection circuits, and high-voltage switching. It may also be used in applications that require fast switching and high forward conductance, such as digital power converters and power management.

Working Principle

SK18-TP is a self-aligned, two-terminal, double-diffused rectifier diode featuring a built-in Schottky contact. When connected to an AC or a DC power source, the junction between the anode and the cathode is forward biased, allowing current to flow. The junction between the anode and the cathode is optimally designed, allowing it to remain operational even at very high switching speeds. In addition, its low forward voltage drop minimizes power loss during switching and ensures higher efficiency.

SK18-TP also features an internal Schottky barrier, which prevents reverse current flow and guarantees reverse voltage protection. In addition, it has a low capacitance and may be used in high frequency switching applications, such as frequency converters and power factor correction, where low capacitance is essential.

Conclusion

SK18-TP is an ultra-fast, ultra-sensitive, low power, and low forward voltage drop during turn-on rectifier diode that is perfect for portable applications, such as consumer electronics, and power supply management. It features a double-diffused planar structure and is available in the SOT-3 plastic package. It is ideal for applications that require fast switching and high forward conductance, such as frequency converters and digital power converters, as it has a low forward voltage drop, preventing power loss during switching, and a low capacitance, allowing for use in high frequency switching applications.
