SMCJ12CA

The SMCJ12CA is a specific model of transient voltage suppressor (TVS) diode manufactured by Bourns, Inc. This component is designed to protect sensitive electronic devices from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or power surges.

Key Features and Specifications:

1. Type and Functionality:

   • The SMCJ12CA is a unidirectional TVS diode, meaning it is designed to clamp voltage in one direction, providing protection for circuits that require a specific polarity.

2. Voltage Rating:

   • The device has a breakdown voltage of approximately 12 volts, which means it will start to conduct and clamp the voltage when it exceeds this threshold. This is crucial for protecting downstream components from overvoltage conditions.

3. Peak Power Rating:

   • The SMCJ12CA can handle a peak power rating of around 600 watts, making it suitable for applications that may experience significant transient events.

4. Package Type:

   • It is typically housed in a DO-214AA (SMC) package, which is a surface-mount device (SMD) that allows for easy integration into various circuit designs. The package is designed for efficient thermal dissipation and robust performance.

5. Clamping Voltage:

   • The clamping voltage is specified at a certain peak pulse current, which indicates the maximum voltage the diode will allow to pass through during a transient event. This is a critical parameter for ensuring that sensitive components are not exposed to damaging voltages.

6. Capacitance:

   • The SMCJ12CA features low capacitance, which is beneficial for high-speed data lines, as it minimizes signal distortion and maintains signal integrity.

7. Operating Temperature Range:

   • The device is rated for a wide operating temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

8. Applications:

   • This TVS diode is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial applications where overvoltage protection is essential.

9. Compliance and Standards:

   • The SMCJ12CA is compliant with various industry standards, ensuring reliability and performance in critical applications.

Summary:

The SMCJ12CA from Bourns, Inc. is a robust transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. With its specific voltage rating, high power handling capability, and compact package design, it is an ideal choice for a wide range of applications requiring reliable overvoltage protection.
