SMAJ26A

The SMAJ26A 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 automotive, telecommunications, and consumer electronics.

Key Features:

1. Voltage Rating: The SMAJ26A has a breakdown voltage of approximately 26 volts, making it suitable for clamping voltage transients that exceed this threshold. Its reverse standoff voltage is typically around 23 volts, allowing it to operate safely under normal conditions.

2. Power Dissipation: The device can handle a peak power dissipation of up to 400 watts, which is crucial for absorbing high-energy transients without sustaining damage. This capability ensures that the connected circuitry remains protected during voltage spikes.

3. Package Type: The SMAJ26A is housed in a DO-214AA (SMA) 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. Response Time: The SMAJ26A features a fast response time, typically in the nanosecond range, allowing it to react quickly to transient events. This rapid response is essential for protecting sensitive components from damage due to voltage surges.

5. Clamping Voltage: The clamping voltage of the SMAJ26A is designed to be low, ensuring that the voltage seen by the protected components remains within safe limits during transient events. This characteristic is vital for preventing damage to integrated circuits and other sensitive devices.

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

7. Applications: The SMAJ26A is commonly used in applications such as power supply protection, data line protection, and automotive electronics, where it safeguards against electrostatic discharge (ESD) and other voltage transients.

8. Compliance and Standards: The SMAJ26A meets various industry standards for reliability and performance, ensuring that it can be used in critical applications where compliance is necessary.

Summary:

In summary, the SMAJ26A from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its combination of high power handling, fast response time, and compact packaging makes it an ideal choice for a wide range of applications requiring overvoltage protection.
