SMAJ30CA

The SMAJ30CA is a specific type of transient voltage suppressor (TVS) diode manufactured by Yangjie Electronic Technology. This component is designed to protect sensitive electronic circuits from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching events in power circuits.

Key Features:

1. Voltage Rating: The SMAJ30CA has a breakdown voltage of approximately 30 volts, making it suitable for applications that require clamping of voltage spikes around this level. The device is designed to activate and conduct when the voltage exceeds this threshold, thereby diverting excess energy away from sensitive components.

2. Power Dissipation: This TVS diode can handle a peak power dissipation of around 400 watts for a short duration, which allows it to absorb significant energy from transient events without failing. This characteristic is crucial for protecting circuits in high-energy environments.

3. Package Type: The SMAJ30CA is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) configuration. This package is compact and designed for efficient thermal management, making it suitable for modern electronic designs where space is at a premium.

4. Response Time: The device features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to transient events. This rapid response is essential for minimizing the risk of damage to downstream components.

5. Clamping Voltage: The clamping voltage of the SMAJ30CA is specified to be low, which means that it will limit the voltage seen by the protected circuit to a safe level during a transient event. This is critical for ensuring the longevity and reliability of sensitive electronic components.

6. Temperature Range: The operating temperature range for the SMAJ30CA is typically from -55°C to +150°C, allowing it to function effectively in a variety of environmental conditions, from extreme cold to high heat.

7. Applications: The SMAJ30CA is commonly used in various applications, including automotive electronics, telecommunications, consumer electronics, and industrial equipment. It is particularly useful in circuits where overvoltage protection is necessary, such as power supply lines, data lines, and signal lines.

8. Compliance and Standards: The device is often compliant with various industry standards for safety and performance, making it a reliable choice for engineers looking to meet regulatory requirements in their designs.

Conclusion:

In summary, the SMAJ30CA from Yangjie Electronic Technology is a robust and efficient 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 ideal choice for a wide range of applications in modern electronic systems.
