TVS – Diodes are a type of electronic component that are used to protect sensitive electronics from power transients like ESD, EMI, or lightning. The PGSMAJ28CA E3G is a bidirectional Transient Voltage Suppressor (TVS) Diode specifically designed to offer high surge protection against ESD, EFT, and lightning in automotive applications. This TVS diode is low capacitance, low clamping voltage, and is able to absorb ESD and EFT events up to 28kV of Contact Discharge and up to 40kV of Air Discharge.

The PGSMAJ28CA E3G is designed for applications that require excellent protection from ESD and EFT, as well as high levels of reverse leakage current. It has a low maximum on-resistance, low reverse current and fast clamping response time, making it ideal for automotive applications that require high surge protection. In addition, its low capacitance makes it suitable for high frequency applications.

The working principle of the PGSMAJ28CA E3G is based on a zener diode and a transistor. The zener diode is connected in parallel with the transistor, forming a voltage clamp. The zener diode limits the voltage while the transistor conducts the surge current away from the protected circuit to ground. This diode is designed to break down when a specific voltage threshold is reached, providing protection by clamping the maximum voltage and diverting the energy of the transient away from sensitive components or system.

The PGSMAJ28CA E3G can be used in a variety of automotive applications, such as engines controllers, brakes controllers, ECUs, Anti-lock Brake Systems, and more. Its reverse current can be used to detect ashort-circuit, and its low capacitance makes it well-suited for high frequency applications. In addition, its low capacitance also makes this diode the ideal solution for applications that require both ESD protection and fast switching, such as power switching circuits.

The PGSMAJ28CA E3G is designed to provide excellent protection from ESD, EFT, and lightning in automotive applications. Its low on-resistance and fast clamping response time make it well-suited for a wide variety of power applications, and its low capacitance makes it the perfect choice for high frequency applications. This TVS diode is an ideal solution for applications that require both ESD protection and fast switching. It offers reliable and effective protection from transient voltage surges, making it the perfect choice for automotive applications.
