SMBJ30A

The SMBJ30A is a type of transient voltage suppressor (TVS) diode manufactured by Shenzhen Jinkaisheng Electronics. 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 SMBJ30A has a breakdown voltage of approximately 30 volts, making it suitable for applications that require clamping at this voltage level. The device is designed to activate and shunt excess voltage away from sensitive components when the voltage exceeds its breakdown threshold.

2. Power Dissipation: The diode can handle a peak power dissipation of around 600 watts, which allows it to absorb significant energy during transient events without failing. This high power rating is crucial for protecting circuits in high-energy environments.

3. Package Type: The SMBJ30A is housed in a surface-mount package, specifically the SMB (DO-214AA) package. This package type is compact and allows for easy integration into printed circuit boards (PCBs), making it ideal for space-constrained applications.

4. Response Time: The device features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to voltage spikes and provide immediate protection to downstream components.

5. Temperature Range: The SMBJ30A operates effectively over a wide temperature range, typically from -55°C to +150°C. This makes it suitable for use in various environments, including industrial and automotive applications.

6. Capacitance: The diode has a low capacitance value, which minimizes its impact on signal integrity in high-speed data lines. This characteristic is particularly important in communication and data transmission applications.

7. Applications: The SMBJ30A is commonly used in a variety of applications, including telecommunications, consumer electronics, automotive electronics, and industrial equipment. It is particularly effective in protecting sensitive ICs, microcontrollers, and other components from voltage transients.

8. Compliance and Standards: The device typically complies with various industry standards for reliability and performance, ensuring that it meets the requirements for use in critical applications.

Conclusion:

The SMBJ30A from Shenzhen Jinkaisheng Electronics is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its combination of high power handling, fast response time, and compact packaging makes it an excellent choice for a wide range of applications where voltage transients pose a risk to sensitive components.
