SMBJ12CA

The SMBJ12CA from Ruilon 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 power supplies, telecommunications, and automotive electronics.

Physical Characteristics:

• Package Type: The SMBJ12CA is housed in a DO-214AA (SMB) package, which is a surface-mount device that provides a compact footprint while ensuring efficient heat dissipation.
• Dimensions: The typical dimensions of the SMB package are approximately 5.2 mm in length, 3.5 mm in width, and 1.5 mm in height, making it suitable for space-constrained applications.
• Material: The body of the diode is made from a durable plastic material that is resistant to moisture and environmental factors, ensuring longevity and reliability in various operating conditions.

Electrical Characteristics:

• Reverse Stand-Off Voltage (V_RWM): The SMBJ12CA has a reverse stand-off voltage of 12 volts, which means it can withstand this voltage level without conducting.
• Clamping Voltage (V_C): Under surge conditions, the clamping voltage is typically around 20.5 volts, providing a safe limit to protect downstream components from damage.
• Peak Power Dissipation: The device can handle peak power dissipation of up to 600 watts for a short duration, making it effective against high-energy transients.
• Operating Temperature Range: The SMBJ12CA operates effectively within a temperature range of -55°C to +150°C, allowing it to function in a variety of environments.

Performance Features:

• Low Leakage Current: The diode exhibits low leakage current, which is crucial for maintaining the efficiency of the circuit and preventing unnecessary power loss.
• Fast Response Time: The SMBJ12CA is designed to respond quickly to voltage spikes, ensuring that sensitive components are protected almost instantaneously.
• Bidirectional Protection: This device provides bidirectional protection, meaning it can clamp voltage spikes in both positive and negative directions, making it versatile for AC and DC applications.

Applications:

The SMBJ12CA is ideal for use in:

• Consumer Electronics: Protecting devices such as smartphones, tablets, and laptops from voltage surges.
• Automotive Systems: Safeguarding electronic control units (ECUs) and other sensitive components in vehicles.
• Telecommunications: Ensuring the reliability of communication equipment by protecting against lightning strikes and other transients.
• Industrial Equipment: Providing overvoltage protection in machinery and control systems.

In summary, the SMBJ12CA from Ruilon is a highly effective transient voltage suppressor that combines compact design, robust performance, and versatility, making it an essential component for protecting electronic circuits from damaging voltage spikes.
