SMBJ5.0A

The SMBJ5.0A from Ruilon 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 telecommunications, automotive electronics, and consumer electronics.

Key Features:

1. Voltage Rating: The SMBJ5.0A is designed to clamp transient voltages at a breakdown voltage of approximately 5.0 volts, making it suitable for protecting circuits operating at low voltage levels.

2. Power Dissipation: This TVS diode can handle a peak power dissipation of up to 600 watts, allowing it to absorb significant energy from voltage spikes without failing.

3. Package Type: The device is housed in a surface-mount SMB package, which is compact and allows for easy integration into various circuit designs. The SMB package typically measures around 5.2 mm x 6.6 mm, making it suitable for space-constrained applications.

4. Response Time: The SMBJ5.0A features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to transient events and protect downstream components effectively.

5. Clamping Voltage: The clamping voltage is low, which minimizes the risk of damage to sensitive components during transient events. This characteristic is crucial for maintaining the integrity of the circuit.

6. Operating Temperature Range: The device operates effectively over a wide temperature range, typically from -55°C to +150°C, ensuring reliability in various environmental conditions.

7. Low Leakage Current: The SMBJ5.0A exhibits low leakage current under normal operating conditions, which helps to conserve power and reduce heat generation in the circuit.

8. Applications: Common applications for the SMBJ5.0A include ESD protection, surge protection in power supplies, and safeguarding data lines in communication devices.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 5.0V
• Breakdown Voltage (V_BR): Typically around 5.0V
• Clamping Voltage (V_C): Specified at a certain peak pulse current, ensuring that it remains within safe limits for connected components.
• Peak Pulse Power (P_PP): 600W for a 10/1000μs waveform.

Conclusion:

The SMBJ5.0A from Ruilon is an essential component for engineers looking to enhance the reliability and durability of their electronic designs.
