Introduction

TVS diodes are components used to protect electronic circuits from high-voltage surge events. SMBJ16CAHM4G is a particular type of transient voltage suppression diode designed to protect against high-voltage events. It is designed to minimize the risk of component failure due to transients and surges, and it is also an effective way to ensure product quality.

Application Field

The SMBJ16CAHM4G is a transient voltage suppression diode which is designed for use in electrical and electronic devices such as computers, deep-space rocket systems, smartphones, and tablets. The device can be used to protect against electrostatic discharge (ESD) and electrical fast transient events. It can also be used to protect against surges caused by lightning strikes, power line faults, and other high-power events.The SMBJ16CAHM4G TVS diode is particularly well suited for use in EMI/RFI applications, where it can be used to suppress the electromagnetic and radio frequency interference (EMI/RFI) that can interfere with normal device operation. It can also be used in automotive applications, such as those involving solenoid motors, pumps, and other actuators.

Working Principle

The SMBJ16CAHM4G TVS diode works by suppressing transients that might otherwise damage sensitive electrical components. It is a zener-style diode, which means it will break down at a predetermined voltage. When the voltage across the diode exceeds this breakdown voltage, it triggers an avalanche breakdown that allows current to flow in a reverse direction. This rush of current serves to protect the sensitive components in the circuit.The device also comes with a reverse polarity protection feature, meaning that it can protect against reversed polarity transients. This allows it to be used in circuits with multiple power sources which may be connected with opposite polarities.

Conclusion

The SMBJ16CAHM4G TVS diode is an effective way of protecting electronic circuits from high-voltage surge events. It is particularly well suited for use in EMI/RFI applications and automotive applications. Furthermore, its reverse polarity protection feature makes it suitable for use in circuits with multiple power sources which may be connected with opposite polarities.
