The SMBJ28HE3/5B is a state-of-the-art low power Transient Voltage Suppressor Diode (TVS). The device offers high power ratings and superior electrical performance over a wide temperature range (−65 °C to 150 °C). This TVS diode is easy to install and is resistant to high levels of electrostatic discharge. It provides reliable protection against overvoltages in a wide range of applications including high-speed data communication, automotive and home electronics.

SMBJ28HE3/5B is a two-line, single-pole, single-throw (SPST) type of TVS diode. It is designed specifically for protecting high-speed telecommunications equipment against overvoltage damage caused by lightning surges and other static discharges. The low capacitance and low clamping voltage of this diode make it the ideal choice for protecting telecom equipment. It offers a great combination of line-drive performance along with high surge capability, making it an ideal solution for all high-speed data applications.

The basic working principle of the SMBJ28HE3/5B is to reduce the voltage (or voltage surge) of an applied signal. It works by utilizing a junction metal oxide semiconductor field effect transistor (MOSFET) and a zener diode. When a voltage past the breakdown voltage (Vce) is applied, the MOSFET acts as a switch and the zener diode clamps the maximum possible voltage. This clamping action limits or completely eliminates an overvoltage surge before it can reach sensitive components in the device.

The SMBJ28HE3/5B is a great choice for protecting any device from damage due to overvoltage. It is suitable for use in a variety of applications including DC/DC converters, automotive, telecom, consumer, industrial, and computer systems. The device offers a maximum surge rating of 28A and is rated with a peak pulse power as high as 500W. The device also offers a very low leakage current rating of 0.1 μA, which makes it ideal for applications where low capacitance is desired.

The SMBJ28HE3/5B is an advanced and reliable form of protection from overvoltage surges. Its high power rating and low clamping voltage make it an ideal choice for any high-speed data communication, automotive, and home electronics application. The device is easy to install and is resistant to electrostatic discharge ensuring complete protection against voltage surges. It is also accompanied by a wide temperature range, making it suitable for a variety of applications. Thus, the SMBJ28HE3/5B is a great choice for any TVS diode application.
