SMAJ15CA

The SMAJ15CA from Leiditech is a robust and reliable transient voltage suppressor (TVS) diode designed to protect sensitive electronic components from voltage spikes and transients. This component is particularly useful in applications where overvoltage protection is critical, such as in automotive, telecommunications, and consumer electronics.

Key Features:

1. Voltage Rating: The SMAJ15CA is rated for a breakdown voltage of approximately 15 volts, making it suitable for clamping voltage spikes that exceed this threshold. This ensures that connected devices are safeguarded against potentially damaging surges.

2. Power Dissipation: The device 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 transients.

3. Package Type: The SMAJ15CA is housed in a DO-214AA (SMA) package, which is compact and designed for surface mount applications. This package type allows for easy integration into circuit boards while minimizing space requirements.

4. Response Time: The diode exhibits a fast response time, typically in the nanosecond range, ensuring that it can react quickly to voltage spikes and provide immediate protection to downstream components.

5. Temperature Range: The operating temperature range for the SMAJ15CA is typically from -55°C to +150°C, making it suitable for use in a variety of environments, including those with extreme temperatures.

6. Low Leakage Current: The device features low leakage current characteristics, which helps to maintain the efficiency of the circuit and reduces the risk of false triggering during normal operation.

7. Applications: Common applications for the SMAJ15CA include ESD protection for data lines, power supply protection, and safeguarding sensitive components in automotive electronics, industrial equipment, and consumer devices.

Electrical Characteristics:

• Reverse Stand-off Voltage (V_R): 15V
• Clamping Voltage (V_C): Typically around 24V at a specified peak pulse current.
• Peak Pulse Current (I_PP): Can handle up to 30A for a specified duration, ensuring robust protection against high-energy transients.

Conclusion:

The SMAJ15CA from Leiditech is an essential component for engineers and designers looking to enhance the reliability and longevity of their electronic devices. Its combination of high power handling, fast response time, and compact packaging makes it an ideal choice for a wide range of applications requiring transient voltage suppression.
