SMBJ5.0CA

The SMBJ5.0CA is a transient voltage suppressor (TVS) diode manufactured by Bourns, Inc. It is designed to protect sensitive electronic components from voltage spikes and transients, such as those caused by electrostatic discharge (ESD) or lightning strikes.

Key Features:

1. Voltage Rating: The SMBJ5.0CA is rated for a breakdown voltage of approximately 5.0 volts, making it suitable for protecting circuits that operate at low voltage levels.

2. Power Dissipation: This component can handle a peak power dissipation of around 600 watts, which allows it to absorb significant energy from transient events without failing.

3. Package Type: The SMBJ5.0CA is housed in a surface-mount package, specifically the SMB (DO-214AA) package, which is compact and suitable for automated assembly processes. This package type is designed for efficient thermal management and provides a low profile for space-constrained applications.

4. Clamping Voltage: The clamping voltage is typically around 8.0 volts at a specified peak pulse current, ensuring that the voltage across the protected device remains within safe limits during transient events.

5. Response Time: The SMBJ5.0CA has a fast response time, which is crucial for protecting sensitive components from rapid voltage spikes.

6. Operating Temperature Range: The diode operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Applications: This TVS diode is commonly used in applications such as telecommunications, automotive electronics, consumer electronics, and industrial equipment, where protection from voltage transients is essential.

8. RoHS Compliance: The SMBJ5.0CA is compliant with RoHS (Restriction of Hazardous Substances) regulations, ensuring that it is free from certain hazardous materials, making it environmentally friendly.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 5.0 V
• Breakdown Voltage (V_BR): 5.6 V (min), 6.2 V (max)
