STTH2002CFP

STTH2002CFP Application Field and Working Principle

The STTH2002CFP is a high power rectifier suitable for applications in an uncontrolled rectification in off-line SMPS (Switched Mode Power Supply) and DC/DC converters. The STTH2002CFP is a very efficient surge and avalanche current rectifier (200V, 2000A) and it has a low reverse leakage current making it suitable for applications in the rectification of direct current from alternating current. It is also suitable for continuous high frequency operation.

The STTH2002CFP can be easily isolated from its high voltage environment through its isolated flat package technology. It has a blocking voltage of 200V and a surge rated current of 2000A, making it suitable for applications like lighting ballasts, DC/DC converters, off-line SMPS and AC/DC converters. Its reverse voltage of 15V ensures it can work in both half wave and bridge rectifier configurations. Its overall dimensions are 11.50 mm by 8.10 mm, making it very compact and ideal for high density integration.

Working Principle

The STTH2002CFP rectifier works on the preset principle of reverse biased diode characteristic. When in reverse biased diode characteristics mode, the diode conducts electricity in the forward direction and blocks electricity in the reverse direction. This is the exact basic functionality of a rectifier. The STTH2002CFP is built to a very high standard and can perform poorly when subjected to extreme temperature, humidity, voltage and current.

The rectifier also has a peak reverse current of 0.020 amps, which is a basic criterion for an efficient rectifier performance. Additionally, the working current range is from 200A to 2000A, making the STTH2002CFP suitable for applications requiring ample power, spot welding and power switching. The recovery time of the rectifier is also quite low and the device is able to restore itself within few nanoseconds. This helps it in achieving continuous switching capability in applications like motor control, DC/DC converters, off-line SMPS.

Applications

The STTH2002CFP can be used in a wide range of applications such as: DC/DC converters, off-line SMPS, AC/DC converters, capacitor discharge, welders, solar PV installations, LED lighting ballasts and more. Additionally, this device can also be used in high power switching applications such as motor control, frequency control, island protection and fault detection. As seen, the STTH2002CFP offers an efficient, reliable, and cost effective solution for an array of applications.

Conclusion

The STTH2002CFP is a very useful and reliable high power rectifier designed for operations in extreme temperatures, high voltage and AC conditions. It is highly suitable for a variety of applications which require high power switching and rectification of direct current from alternate current, including lighting ballasts, DC/DC converters, motor control and more. Aside from that, this device is also cost effective and durable, making it an excellent choice for a wide range of applications.
