SMBJ24CA-QH belongs to the family of TVS (Transient Voltage Suppressor) – Diodes. TVS is an electrical component that helps to protect circuits from high voltage, transient glitches and power surge. It is one of the essential components used in today’s high-powered electronic devices.

Application Field

The SMBJ24CA-QH TVS diode is specifically designed for the application field of reverse polarity protection. It is widely used to protect microprocessors from damage caused by negative voltages. The device has an operating voltage equal to 24V and a very low leakage current.

All types of circuits where reverse polarity protection is required can be easily protected by using this diode. It is mainly used in automobile, communications, consumer electronics and aerospace industries. The device is also suitable for high-power and high-current circuits to provide protection from the external ESD (electrostatic discharge).

Working Principle

The working principle of the SMBJ24CA-QH TVS diode involves two stages of protection. It reacts to the surge voltage in the following manner:

First, it acts as a unidirectional short circuit and absorbs the transient energy. This reduces the voltage by clipping it off at a certain level. This protects the connected equipment from the surge.

Second, the device acts as an Open Circuit which limits the current. It reduces the current and also limits the energy flowing into the circuit. This eliminates damage to the connected equipment.

The SMBJ24CA-QH is designed to have a very fast response time which enables it to provide good protection against transient over-voltage conditions. It also has a very low peak pulse power rating which helps in preventing the loss of energy during the high voltage surge.

The device is designed to have high holding voltage and low capacitance. This allows the device to provide effective surge protection to the connected components. It is also highly reliable and has low thermal runaway.

The SMBJ24CA-QH diode is also used in the high-frequency signals in the automotive and aerospace industries. It is used to provide stable protection against ESD and short circuit faults. The device also has a better ESD protection capability as compared to other TVS diodes.

The SMBJ24CA-QH diode is an ideal device for providing protection to sensitive electronic components. It is used in a variety of applications and provides effective protection against high voltage surge, transient glitches, negative voltages and ESD.
