SMAJ13CA-TR TVS - Diodes by STMicroelectronics

The SMAJ13CA-TR is a specific type of transient voltage suppressor (TVS) diode manufactured by STMicroelectronics. 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 inductive load switching.

Key Features:

1. Type and Configuration:

   • The SMAJ13CA-TR is a unidirectional TVS diode, meaning it is designed to conduct current in one direction and clamp voltage spikes to a safe level in that direction.

2. Voltage Rating:

   • The device has a breakdown voltage of approximately 13 volts, making it suitable for protecting circuits operating at or below this voltage level.

3. Peak Power Rating:

   • It can handle peak power ratings of up to 600 watts, which allows it to absorb significant energy from transient events without failing.

4. Clamping Voltage:

   • The clamping voltage is typically around 22 volts at a specified peak pulse current, ensuring that the voltage across the protected device remains within safe limits during a transient event.

5. Capacitance:

   • The SMAJ13CA-TR features low capacitance, which is beneficial for high-speed data lines, as it minimizes signal distortion and maintains signal integrity.

6. Package Type:

   • The diode is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) that allows for easy integration into various circuit designs. The compact size of the package makes it suitable for space-constrained applications.

7. Operating Temperature Range:

   • The device operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for use in harsh environments.

8. Applications:

   • The SMAJ13CA-TR is commonly used in automotive, telecommunications, consumer electronics, and industrial applications where protection against voltage transients is critical. It is ideal for safeguarding microcontrollers, communication lines, and other sensitive components.

9. Compliance and Standards:

   • The device complies with various industry standards, ensuring reliability and performance in critical applications.

Summary:

The SMAJ13CA-TR from STMicroelectronics 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, low clamping voltage, and compact packaging makes it an excellent choice for a wide range of applications requiring transient protection.
