SMBJ26A

The SMBJ26A 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 SMBJ26A is rated for a breakdown voltage of approximately 26 volts, making it suitable for clamping voltage spikes that exceed this threshold. Its reverse standoff voltage is typically around 24.5 volts.

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

3. Package Type: The SMBJ26A is housed in a DO-214AA (SMB) package, which is a surface-mount device (SMD) that provides a compact footprint. This package is designed for efficient thermal management and can be easily integrated into various circuit designs.

4. Response Time: The SMBJ26A 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 specified at a certain peak pulse current, which indicates the maximum voltage the device will allow during a transient event. This is crucial for ensuring that sensitive components are not exposed to damaging voltages.

6. Operating Temperature Range: The SMBJ26A operates effectively over a wide temperature range, typically from -55°C to +150°C, making it suitable for various environmental conditions.

7. Applications: Common applications for the SMBJ26A include ESD protection, surge protection in power lines, and safeguarding sensitive circuits in automotive and industrial environments.

8. Compliance and Standards: The device is compliant with various industry standards, ensuring reliability and performance in critical applications.

Summary:

The SMBJ26A 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 high power handling, fast response time, and compact packaging makes it an ideal choice for a wide range of applications where overvoltage protection is necessary.
