SMBJ10CA

The SMBJ10CA 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 SMBJ10CA is rated for a breakdown voltage of approximately 10 volts, making it suitable for clamping voltage spikes that exceed this threshold. The device is designed to respond quickly to transient events, ensuring that connected components are shielded from potentially damaging overvoltage conditions.

2. Power Dissipation: The device can handle a peak power dissipation of up to 600 watts for a short duration, which allows it to absorb significant energy from transient events without failing. This capability is essential for protecting sensitive circuits from high-energy surges.

3. Package Type: The SMBJ10CA is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) configuration. This package is compact and designed for efficient thermal management, making it suitable for high-density circuit board layouts.

4. Clamping Voltage: The clamping voltage of the SMBJ10CA is specified to be low, ensuring that the voltage across the protected load remains within safe limits during transient events. This characteristic is crucial for safeguarding sensitive components like microcontrollers, FETs, and other semiconductor devices.

5. Response Time: The SMBJ10CA features a fast response time, typically in the nanosecond range, which allows it to react quickly to voltage spikes, thereby minimizing the risk of damage to downstream components.

6. Operating Temperature Range: The device is designed to operate over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions, including automotive and industrial applications.

7. Applications: Common applications for the SMBJ10CA include ESD protection, surge protection in power lines, and safeguarding data lines in communication equipment. It is also used in power supply circuits and automotive electronics to protect against load dump and other transient events.

8. Compliance and Standards: The SMBJ10CA meets various industry standards for reliability and performance, ensuring that it can be used in critical applications where compliance is necessary.

Conclusion:

The SMBJ10CA from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its combination of low clamping voltage, high power dissipation capability, and fast response time makes it an ideal choice for a wide range of applications in modern electronic systems.
