SMAJ8.0CA

The SMAJ8.0CA is a specific type of transient voltage suppressor (TVS) diode manufactured by Littelfuse Inc. This component is designed to protect sensitive electronic devices from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or switching surges.

Key Features and Specifications:

1. Type: The SMAJ8.0CA is a unidirectional TVS diode, meaning it is designed to conduct current in one direction and clamp voltage spikes to a safe level.

2. Peak Power Dissipation: It typically has a peak power dissipation rating of around 600 watts, which allows it to absorb significant energy from transient events without being damaged.

3. Reverse Stand-Off Voltage (V_RWM): The device has a reverse stand-off voltage of 8.0 volts, which is the maximum voltage that can be applied to the diode without it conducting. This makes it suitable for protecting circuits that operate at low voltage levels.

4. Clamping Voltage (V_C): When a transient event occurs, the clamping voltage is the maximum voltage that the diode will allow to pass through. For the SMAJ8.0CA, this is typically around 12.0 volts, ensuring that connected components are protected from excessive voltage.

5. Breakdown Voltage (V_BR): The breakdown voltage is the voltage at which the diode begins to conduct significantly. For the SMAJ8.0CA, this is usually specified in the range of 8.8 to 9.8 volts.

6. Capacitance: The diode has a low capacitance value, which is beneficial for high-speed applications as it minimizes signal distortion.

7. Package Type: The SMAJ8.0CA is housed in a DO-214AC (SMA) package, which is a surface-mount device (SMD) that is compact and suitable for automated assembly processes.

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

9. Applications: The SMAJ8.0CA is commonly used in consumer electronics, telecommunications, automotive electronics, and industrial equipment where overvoltage protection is critical.

10. Compliance and Standards: Littelfuse ensures that the SMAJ8.0CA meets various industry standards for reliability and performance, making it a trusted choice for engineers and designers.

Summary:

The SMAJ8.0CA from Littelfuse Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for low-voltage electronic circuits. Its combination of high power dissipation, low clamping voltage, and compact packaging makes it an ideal choice for a wide range of applications where voltage transients can pose a risk to sensitive components.
