SMAJ30CA

The SMAJ30CA from AnBon is a robust and reliable transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes and transients. This device is particularly useful in applications where overvoltage protection is critical, such as in automotive, telecommunications, and industrial equipment.

Physical Characteristics: The SMAJ30CA is housed in a DO-214AC (SMA) package, which is a surface-mount device (SMD) that is compact and easy to integrate into various circuit designs. The package typically features a cylindrical shape with flat sides, allowing for efficient heat dissipation. The diode is usually marked with the manufacturer's logo, part number, and polarity indicators, ensuring easy identification during assembly and maintenance.

Electrical Specifications:

• Reverse Stand-Off Voltage (V_RWM): The SMAJ30CA has a reverse stand-off voltage of 30V, making it suitable for protecting circuits operating at or below this voltage level.
• Clamping Voltage (V_C): Under specified surge conditions, the clamping voltage is typically around 45V, which indicates the maximum voltage the device will allow before it begins to conduct and divert excess energy away from sensitive components.
• Peak Power Dissipation: The device can handle peak power dissipation of up to 400W for a short duration, making it effective against high-energy transients.
• Operating Temperature Range: The SMAJ30CA is designed to operate within a wide temperature range, typically from -55°C to +150°C, ensuring reliability in various environmental conditions.

Performance Features: The SMAJ30CA is characterized by its fast response time, which is crucial for protecting against fast transients such as electrostatic discharge (ESD) and lightning strikes. Its low leakage current ensures minimal impact on the circuit's performance during normal operation. Additionally, the device is designed to meet various industry standards for reliability and safety, making it a trusted choice for engineers.

Applications: This TVS diode is commonly used in a variety of applications, including:

• Automotive electronics, where it protects sensitive components from voltage spikes due to load dumps or inductive kickback.
• Communication equipment, safeguarding against surges that can occur in data lines.
• Industrial control systems, providing protection for sensors and actuators from transient voltages.

In summary, the SMAJ30CA from AnBon is a versatile and efficient transient voltage suppressor that offers essential protection for electronic circuits, ensuring their longevity and reliability in demanding environments. Its combination of compact design, high power handling capability, and wide operating temperature range makes it an ideal choice for a variety of applications.
