SMBJ28A

The SMBJ28A is a type of transient voltage suppressor (TVS) diode manufactured by FTR (Fujitsu Component Limited). It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as electrostatic discharge (ESD), lightning strikes, or power surges.

Key Features:

1. Voltage Rating: The SMBJ28A has a breakdown voltage of approximately 28 volts, making it suitable for applications where the operating voltage is around this level. It is designed to clamp voltage spikes effectively while allowing normal operation under standard conditions.

2. Power Dissipation: This component can handle a peak power dissipation of up to 600 watts, which is crucial for absorbing high-energy transients without failing. This capability ensures that the connected devices remain protected during voltage surges.

3. Package Type: The SMBJ28A is housed in a surface-mount package, specifically the SMB (DO-214AA) package. This package type is compact and allows for easy integration into various circuit designs, making it ideal for modern electronic applications.

4. Response Time: The diode exhibits a fast response time, which is essential for effectively clamping voltage spikes before they can damage sensitive components. This rapid response helps in maintaining the integrity of the circuit.

5. Temperature Range: The operating temperature range for the SMBJ28A typically spans from -55°C to +150°C, allowing it to function reliably in a wide variety of environmental conditions.

6. Capacitance: The diode has a low capacitance value, which minimizes the impact on signal integrity in high-speed applications. This feature is particularly important in data communication and RF applications where signal distortion must be kept to a minimum.

7. Applications: The SMBJ28A is commonly used in various applications, including telecommunications, consumer electronics, automotive electronics, and industrial equipment. It is particularly useful in protecting circuits that are exposed to high-voltage transients.

Summary:

In summary, the SMBJ28A from FTR is a robust transient voltage suppressor diode that provides effective protection against voltage spikes in a compact surface-mount package. Its high power dissipation capability, fast response time, and wide operating temperature range make it an excellent choice for safeguarding sensitive electronic components in diverse applications.
