Description

The SMAJ12CA 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 SMAJ12CA is rated for a breakdown voltage of approximately 12 volts, making it suitable for clamping voltage spikes that exceed this threshold. It is designed to handle transient voltages effectively while allowing normal operating voltages to pass through without interference.

  2. Power Dissipation: The device typically has a power dissipation capability of around 400 watts, which allows it to absorb significant energy from transient events without failing. This high power rating ensures reliability in demanding environments.

  3. Package Type: The SMAJ12CA is housed in a DO-214AA (SMA) 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. Response Time: The diode exhibits a fast response time, which is crucial for protecting sensitive components from rapid voltage spikes. This quick action helps to minimize the risk of damage to downstream circuitry.

  5. Temperature Range: The operating temperature range for the SMAJ12CA typically spans from -55°C to +150°C, making it suitable for use in a wide variety of environmental conditions, including harsh industrial and automotive applications.

  6. Capacitance: The device has low capacitance, which is beneficial for high-speed data lines, as it minimizes signal distortion and ensures that the integrity of the data is maintained during operation.

  7. Applications: Common applications for the SMAJ12CA include ESD protection, surge protection in power lines, and safeguarding sensitive components in consumer electronics, automotive systems, and industrial equipment.

Electrical Characteristics:

  • Reverse Stand-off Voltage (V_R): 12V
  • Clamping Voltage (V_C): Typically around 20V at a specified peak pulse current.
  • Peak Pulse Power (P_PP): 400W (for a 10/1000μs waveform).
  • Leakage Current (I_R): Very low, ensuring minimal impact on circuit performance during normal operation.

Conclusion:

The SMAJ12CA 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, fast response time, and compact packaging makes it an ideal choice for a wide range of applications where overvoltage protection is necessary.
