SMAJ5.0CA

The SMAJ5.0CA from Yjsemi is a robust and reliable transient voltage suppressor (TVS) diode 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 power supplies, telecommunications, and automotive electronics.

Key Features:

1. Voltage Rating: The SMAJ5.0CA is designed to clamp voltage spikes at a breakdown voltage of approximately 5.0 volts, making it suitable for low-voltage applications. Its low clamping voltage helps to ensure that connected devices are protected from damaging overvoltage conditions.

2. Power Dissipation: This TVS diode can handle a peak power dissipation of around 400 watts, allowing it to absorb significant energy from transient events without failing. This high power rating is essential for applications that may experience frequent or severe voltage spikes.

3. Package Type: The SMAJ5.0CA is housed in a DO-214AC (SMA) package, which is a surface-mount device (SMD) that provides a compact footprint. This makes it easy to integrate into various circuit designs while saving space on the PCB.

4. Response Time: The device features a fast response time, typically in the nanosecond range, ensuring that it can react quickly to transient events and protect sensitive components effectively.

5. Temperature Range: The SMAJ5.0CA operates over a wide temperature range, typically from -55°C to +150°C, making it suitable for use in harsh environments and ensuring reliability in various operating conditions.

6. Low Leakage Current: The diode exhibits low leakage current under normal operating conditions, which helps to minimize power loss and improve overall circuit efficiency.

7. Applications: Common applications for the SMAJ5.0CA include ESD protection, surge protection in power lines, and safeguarding sensitive ICs in consumer electronics, automotive systems, and industrial equipment.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 5.0V
• Clamping Voltage (V_C): Typically around 9.0V at a specified peak pulse current.
• Peak Pulse Current (I_PP): Can handle up to 30A for a specified duration.
• Capacitance: The device has a low capacitance value, which is beneficial for high-speed data lines, ensuring minimal signal distortion.

Conclusion:

The SMAJ5.0CA from Yjsemi is an essential component for engineers looking to enhance the reliability and durability of their electronic designs. Its combination of low clamping voltage, high power handling capability, and compact packaging makes it an ideal choice for a wide range of applications requiring effective overvoltage protection.
