SMBJ33CA

The SMBJ33CA is a transient voltage suppressor (TVS) diode manufactured by Microdiode Electronics, 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 SMBJ33CA is designed to clamp voltage spikes at a breakdown voltage of approximately 33 volts. This makes it suitable for protecting circuits operating at lower voltage levels, ensuring that any transient voltage does not exceed the safe operating limits of the connected components.

2. Power Dissipation: The device can handle a peak power dissipation of up to 600 watts for a short duration, making it effective in absorbing high-energy transients without sustaining damage.

3. Package Type: The SMBJ33CA is housed in a surface-mount package, specifically the SMB (DO-214AA) package, which is compact and allows for easy integration into various circuit designs. The package is designed for efficient thermal management, ensuring that heat generated during operation is dissipated effectively.

4. Response Time: The SMBJ33CA features a fast response time, typically in the nanosecond range, allowing it to react quickly to voltage spikes and protect sensitive components before damage can occur.

5. Clamping Voltage: The clamping voltage of the SMBJ33CA is specified to be low, ensuring that the voltage seen by the protected circuit remains within safe limits during transient events.

6. Operating Temperature Range: The device is rated for a wide operating temperature range, typically from -55°C to +150°C, making it suitable for use in various environmental conditions.

7. Applications: Common applications for the SMBJ33CA include ESD protection, surge protection in power lines, and safeguarding sensitive components in automotive and industrial electronics.

8. Compliance and Standards: The SMBJ33CA is compliant with various industry standards for reliability and performance, ensuring that it meets the requirements for use in critical applications.

Summary:

In summary, the SMBJ33CA from Microdiode Electronics is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its combination of a suitable breakdown voltage, high power dissipation capability, and fast response time makes it an ideal choice for a wide range of applications where overvoltage protection is necessary.
