SMBJ6.5HE3/5B

The SMBJ6.5HE3/5B is a member of the transient voltage suppression (TVS) diode group, responsible for protecting all of the sensitive electrical components from damage resulting from transient voltages or electrostatic discharges. In this article, we will discuss the application field and working principle of this diode.

Applications of the SMBJ6.5HE3/5B TVS Diode

The SMBJ6.5HE3/5B is a unidirectional, 5W TVS diode. It is suitable for use in a variety of applications and environments, particularly those that require protection from transient voltages or electrostatic discharges. These applications include industrial equipment, medical devices, commercial close-circuit television (CCTV) systems, computers and peripherals, automotive industry components, and consumer electronic products.

In particular, this diode is designed to safeguard sensitive components, such as microprocessors, logic devices, and other semiconductor circuits, from transient voltages or electrostatic discharges that may cause damage or disruption to the system. As such, this diode is ideal for use in any application that requires reliable protection from such disturbances.

Working Principle of the SMBJ6.5HE3/5B TVS Diode

The SMBJ6.5HE3/5B TVS diode works by absorbing the energy from a rise in the voltage level of a signal. It does this by clamping the signal at a predetermined voltage and limiting the current through it. This process is called ``clamping.\'\' The diode can either reduce the magnitude of a voltage transient for a short period of time or completely eliminate it.

When the voltage on the diode rises above its breakdown voltage, the diode begins to conduct current. This in turn causes a voltage drop across the diode and the current is limited to a safe level. As a result, the voltage across the diode falls back to a safe level, clamping the incoming signal and thus protecting the system from any damage.

The diode also works by diverting excessive current away from the system, thereby protecting the sensitive components from overvoltage and current surges. This is done by controlling the current\'s flow from one terminal to the other, ensuring that it does not exceed a safe level.

Conclusion

The SMBJ6.5HE3/5B is a member of the transient voltage suppression (TVS) diode family and is designed to protect sensitive components from transient voltages or electrostatic discharges. It is suitable for use in a variety of applications, including industrial equipment, medical devices, computers and peripherals, automobiles, and consumer electronics. The diode works by clamping the voltage and limiting the current when the voltage rises beyond a predetermined level, and by diverting excessive current away from the system, thereby protecting sensitive components from damage.
