SMAJ30A

The SMAJ30A is a specific type of transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc. It is designed to protect sensitive electronic components from voltage spikes and transients, which can occur due to various factors such as electrostatic discharge (ESD), lightning strikes, or inductive load switching.

Key Features:

1. Voltage Rating: The SMAJ30A has a breakdown voltage of approximately 30 volts, making it suitable for applications where the maximum operating voltage is around this level. It is designed to clamp voltage spikes effectively, ensuring that the voltage does not exceed safe levels for connected components.

2. Power Dissipation: This device can handle a peak power dissipation of up to 400 watts, which allows it to absorb significant energy from transient events without failing. This high power rating is crucial for applications that may experience severe voltage surges.

3. Package Type: The SMAJ30A is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) configuration. This package is compact, making it suitable for space-constrained applications while providing good thermal performance.

4. Response Time: The SMAJ30A features a fast response time, typically in the nanosecond range, which is essential for protecting sensitive electronics from rapid voltage transients.

5. Temperature Range: The operating temperature range for the SMAJ30A is typically from -55°C to +150°C, allowing it to function reliably in a wide variety of environmental conditions.

6. Applications: This TVS diode is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial equipment. It is particularly useful in protecting data lines, power lines, and other sensitive circuits from voltage spikes.

7. Compliance and Standards: The SMAJ30A meets various industry standards for safety and performance, making it a reliable choice for engineers and designers looking for robust transient protection solutions.

Summary:

In summary, the SMAJ30A from Littelfuse Inc. is a reliable and efficient 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, compact packaging, and fast response time makes it an ideal choice for a wide range of applications in modern electronic devices.
