SMBJ10CA

The SMBJ10CA is a type of transient voltage suppressor (TVS) diode manufactured by Thinking Electronics, designed to protect sensitive electronic components from voltage spikes and transients. This component is particularly useful in applications where overvoltage protection is critical, such as in power supply circuits, telecommunications, and automotive electronics.

Key Features:

1. Voltage Rating: The SMBJ10CA is rated for a breakdown voltage of approximately 10 volts, making it suitable for clamping voltage spikes that exceed this threshold. It is designed to respond quickly to transient events, ensuring that connected devices are shielded from potential damage.

2. Power Dissipation: The device can handle a peak power dissipation of around 600 watts, which allows it to absorb significant energy from transient events without failing. This high power rating is essential for applications that may experience severe voltage surges.

3. Package Type: The SMBJ10CA is housed in a DO-214AA (SMB) package, which is a surface-mount design that facilitates easy integration into various circuit boards. The compact size of the package allows for efficient use of space in electronic designs.

4. Temperature Range: The operating temperature range for the SMBJ10CA typically spans from -55°C to +150°C, making it suitable for use in a wide variety of environments, including harsh industrial settings.

5. Low Clamping Voltage: One of the critical advantages of the SMBJ10CA is its low clamping voltage during transient events. This characteristic ensures that the voltage seen by the protected components remains within safe limits, thereby enhancing the reliability of the overall system.

6. Fast Response Time: The device is designed to respond rapidly to voltage spikes, which is crucial for protecting sensitive electronics that can be damaged by even brief overvoltage conditions.

7. Applications: The SMBJ10CA is commonly used in applications such as:

   • Power supply circuits
   • Data line protection
   • Automotive electronics
   • Telecommunications equipment
   • Consumer electronics

Electrical Characteristics:

• Reverse Stand-off Voltage (VRWM): 10V
• Breakdown Voltage (VBR): Typically around 11.2V
• Clamping Voltage (VC): Approximately 15V at a specified peak pulse current
• Peak Pulse Power (PPP): 600W (for 8/20μs waveform)

Conclusion:

The SMBJ10CA from Thinking Electronics is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its combination of high power handling, low clamping voltage, and wide operating temperature range makes it an ideal choice for a variety of applications where overvoltage protection is paramount.
