SMAJ18CA

The SMAJ18CA from AnBon is a robust and reliable transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes and transients. This component is particularly useful in applications where overvoltage protection is critical, such as in automotive, industrial, and consumer electronics.

Key Features:

1. Voltage Rating: The SMAJ18CA has a breakdown voltage of approximately 18 volts, making it suitable for clamping voltage spikes that exceed this threshold. It is designed to handle transient voltages effectively while ensuring that the normal operating voltage remains unaffected.

2. Power Dissipation: This TVS diode can handle a peak power dissipation of around 400 watts, which allows it to absorb significant energy from transient events without failing. This feature is crucial for protecting sensitive circuits from damage.

3. Package Type: The SMAJ18CA is housed in a surface-mount package, specifically the SMA (DO-214AC) package, which is compact and suitable for automated assembly processes. The small footprint makes it ideal for space-constrained applications.

4. Response Time: The diode exhibits a fast response time, typically in the nanosecond range, ensuring that it can react quickly to voltage spikes and provide immediate protection to downstream components.

5. Temperature Range: The operating temperature range for the SMAJ18CA is typically from -55°C to +150°C, allowing it to function reliably in a variety of environmental conditions, including extreme temperatures.

6. Low Leakage Current: The device features low leakage current characteristics, which helps in maintaining energy efficiency and reducing power loss during normal operation.

7. Applications: The SMAJ18CA is suitable for a wide range of applications, including but not limited to:

   • Automotive electronics (e.g., ECU, sensors)
   • Telecommunications equipment
   • Consumer electronics (e.g., smartphones, tablets)
   • Industrial control systems

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 18V
• Clamping Voltage (V_C): Typically around 28V at a specified peak pulse current.
• Peak Pulse Current (I_PP): Can handle up to 30A for a specified duration.

Conclusion:

The SMAJ18CA from AnBon is an essential component for engineers looking to safeguard their electronic designs against voltage transients. Its combination of high power handling, fast response time, and compact packaging makes it a versatile choice for a variety of applications, ensuring the longevity and reliability of sensitive electronic systems.
