SMAJ15CA

The SMAJ15CA is a specific type of transient voltage suppressor (TVS) diode manufactured by Shanghai Prisemi Electronics. This component is designed to protect sensitive electronic circuits from voltage spikes and transients, which can occur due to various factors such as lightning strikes, electrostatic discharge (ESD), or inductive load switching.

Key Features:

1. Voltage Rating: The SMAJ15CA is rated for a breakdown voltage of approximately 15 volts. This means it will start conducting when the voltage exceeds this threshold, effectively clamping the voltage to protect downstream components.

2. Power Dissipation: The device typically has a power dissipation capability of around 400 watts, allowing it to absorb significant energy from transient events without failing.

3. Package Type: The SMAJ15CA is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) configuration. This package is compact, making it suitable for applications where space is limited.

4. Response Time: The diode has a fast response time, which is crucial for protecting sensitive electronics from rapid voltage spikes.

5. Temperature Range: The operating temperature range for the SMAJ15CA is typically from -55°C to +150°C, making it suitable for a wide variety of environments, including industrial and automotive applications.

6. Capacitance: The device features low capacitance, which is important for high-speed data lines, ensuring that it does not interfere with signal integrity.

7. Applications: The SMAJ15CA is commonly used in various applications, including telecommunications, automotive electronics, consumer electronics, and industrial equipment, where overvoltage protection is essential.

8. Compliance: The component often meets various industry standards for reliability and performance, making it a trusted choice for engineers and designers.

Summary:

In summary, the SMAJ15CA from Shanghai Prisemi Electronics is a robust transient voltage suppressor diode designed to protect electronic circuits from voltage transients. With its compact SMA package, high power dissipation capability, and fast response time, it is an ideal choice for a wide range of applications requiring reliable overvoltage protection.
