Working Principle

The STTH802B-TR is a 1SMB series Schottky diode that features a high surge capability, low forward voltage drop, low reverse current, and high efficiency. When reverse biased, the diode conducts reverse current and thus serves as a rectifier in power supplies and other applications. While forward-biased, the diode can act as a voltage regulator or a switch in a wide range of applications.When reverse-biased, the STTH802B-TR operates in a non-conducting state and its construction allows for very low forward voltage drops, making it an ideal solution for rectifier applications because of its low power losses. The anti-parallel Zener diode reduces the peak voltage and current, reducing the forward-voltage drop considerably.When forward-biased, the STTH802B-TR operates in a conducting state and acts as a voltage regulator, due to its low forward voltage, and as a switch, due to its fast switching speed. Its high surge capability and fast recovery time mean that the diode also operates successfully in high power applications, such as in motor control and power conditioning, motor and solenoid starting, frequency converters, and high-voltage switching.

Conclusion

The STTH802B-TR is a 1SMB series Schottky diode comprised of a high surge capability, low forward voltage drop, low reverse current, and high efficiency. This makes it an ideal choice for rectifier applications due to its low power losses and fast switching speeds. As well as being suitable for rectifier and high frequency switching, the STTH802B-TR is also suitable for motor control, power conditioning, motor and solenoid starting, voltage regulation, UPS systems, and frequency converters. With its excellent thermal characteristics and wide operating temperature range, the STTH802B-TR is an ideal solution for high-end and rapid switching applications.
