SMBJ6.5CA

The SMBJ6.5CA is a transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc., 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 SMBJ6.5CA is designed to clamp transient voltages at a breakdown voltage of approximately 6.5 volts. This makes it suitable for protecting circuits that operate at low voltage levels.

2. Power Dissipation: The device 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 SMBJ6.5CA is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that provides a compact footprint. This makes it ideal for space-constrained applications.

4. Response Time: The TVS diode has 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 specified at a certain peak pulse current, which indicates the maximum voltage the device will allow during a transient event before it starts to conduct and divert the excess energy away from the protected circuit.

6. Operating Temperature Range: The SMBJ6.5CA operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Low Leakage Current: The device features low leakage current under normal operating conditions, which helps to minimize power loss and improve overall circuit efficiency.

8. Applications: Common applications for the SMBJ6.5CA include ESD protection, surge protection in power supplies, and safeguarding sensitive components in automotive and industrial electronics.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 6.5V
• Breakdown Voltage (V_BR): Typically around 7.2V
• Clamping Voltage (V_C): Specified at a given peak pulse current
• Peak Pulse Power (P_PP): 600W (for 8/20μs waveform)
• Capacitance: Low capacitance values, ensuring minimal impact on signal integrity in high-speed applications.

Conclusion:

The SMBJ6.5CA from Littelfuse Inc. is a robust and reliable solution for transient voltage suppression, providing essential protection for sensitive electronic components against voltage spikes. Its compact design, high power handling capability, and fast response time make it an excellent choice for a wide range of electronic applications.
