TVS (transient voltage suppressor) diodes are advanced protection devices that are designed to protect low voltage electronic equipment in harsh environments, such as industrial and automotive applications. They are typically used to protect against electrostatic discharges (ESD), induced voltage surges, and other transients. The1SMB28AT3GTVS Diode is a popular choice for many applications and is designed to protect against various transients voltages.

The 1SMB28AT3G is a unidirectional transient voltage suppressor diode designed to protect low voltage electronic equipment from the damages of transients such as ESD and voltage spikes. It is housed in a do-35 package with a glass passivated, fast zener diode, and two low capacitance diodes. The diode features a low clamped voltage with a low breakdown voltage of 21.6V and a peak pulse current rate of 28A. It is designed to provide effective protection and has an operating temperature range of -55°C to +150°C.

The 1SMB28AT3G is among the most popular choice for use in sensitive circuits such as data bus lines, automotive systems, and other low voltage electronic equipment. The device is capable of suppressing high-voltage transients in busy industrial and automotive circuits. It helps to protect sensitive circuits and components from the damages caused by electrostatic discharges and voltage spikes. It is also designed to protect against transient overvoltage caused by lightning or other sources of electromagnetic interference.

The device utilizes a zener diode and two low capacitance diodes to provide the required level of protection. When the incoming transient voltage exceeds the zener voltage, the diode conducts a destructive current which is then limited by the two low capacitance diodes. The clamped voltage is then limited to protect the circuit. The combination of the zener diode and the low capacitance diodes helps to provide a high degree of protection from damaging transients.

In addition, the 1SMB28AT3G is designed to have a faster response time compared to traditional transistors or zener diodes found in the same applications. This makes it ideal for use in high-speed circuits due to its fast switching ability and wide potential voltage absorption range. It also has a high surge current rating which is helpful in scenarios like high energy ESD spikes.

The 1SMB28AT3G is an excellent transient voltage suppressor and is a great choice to protect sensitive circuits from ESD and other transients. It has a wide range of applications and features a combination of fast zeners and low capacitance diodes for maximum protection. The device can be used in industrial, automotive, and other low voltage electronic applications where effective protection is needed.
