SMAJ30A

The SMAJ30A 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 surges.

Key Features:

1. Voltage Rating: The SMAJ30A has a breakdown voltage of approximately 30 volts, making it suitable for applications that require clamping at this voltage level. This allows it to effectively protect circuits operating at lower voltages.

2. Power Dissipation: The device is capable of handling a peak power dissipation of around 400 watts, which is crucial for absorbing high-energy transients without failing.

3. Package Type: The SMAJ30A is housed in a DO-214AC (SMA) package, which is a surface-mount design that allows for easy integration into various circuit boards. The compact size of the package helps save space in electronic designs.

4. Response Time: The diode exhibits a fast response time, which is essential for protecting sensitive components from rapid voltage spikes. This ensures that the clamping action occurs almost instantaneously.

5. Temperature Range: The operating temperature range for the SMAJ30A typically spans from -55°C to +150°C, making it suitable for use in a variety of environments, including industrial and automotive applications.

6. Low Leakage Current: The device features low leakage current characteristics, which helps in maintaining the efficiency of the circuit by minimizing power loss during normal operation.

7. Applications: The SMAJ30A is commonly used in various applications, including telecommunications, consumer electronics, automotive electronics, and industrial equipment. It is particularly useful in protecting data lines, power lines, and sensitive microcontroller inputs.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 30V
• Clamping Voltage (V_C): Typically around 45V at a specified peak pulse current.
• Peak Pulse Current (I_PP): The device can handle a peak pulse current of up to 30A for a short duration.

Conclusion:

The SMAJ30A from Yangjie Electronic Technology 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 capability, fast response time, and compact packaging makes it an ideal choice for a wide range of applications where circuit integrity is critical.
