SMAJ15CA

The SMAJ15CA is a specific model of a transient voltage suppressor (TVS) diode manufactured by Bourns, 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. Voltage Rating: The SMAJ15CA has a breakdown voltage of approximately 15 volts, making it suitable for clamping voltage spikes that exceed this threshold. This helps to prevent damage to downstream components in a circuit.

2. Power Dissipation: The device is capable of handling a peak power dissipation of around 400 watts, which allows it to absorb significant energy during transient events without failing.

3. Package Type: The SMAJ15CA is housed in a DO-214AA (SMA) package, which is a surface-mountable, cylindrical component. This package design is compact, making it ideal for applications where space is limited.

4. Reverse Leakage Current: At a specified reverse voltage, the SMAJ15CA exhibits a low reverse leakage current, which is crucial for maintaining the efficiency of the circuit and preventing unnecessary power loss.

5. Temperature Range: The operating temperature range for the SMAJ15CA typically spans from -55°C to +150°C, allowing it to function reliably in a variety of environmental conditions.

6. Applications: This TVS diode is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial applications where protection against voltage transients is essential.

7. Compliance and Standards: The SMAJ15CA is often compliant with various industry standards, ensuring its reliability and performance in critical applications.

Performance Characteristics:

• Clamping Voltage: The clamping voltage is the maximum voltage that the diode will allow to pass through during a transient event. The SMAJ15CA is designed to clamp voltages effectively, protecting sensitive components from overvoltage conditions.

• Response Time: The response time of the SMAJ15CA is extremely fast, typically in the nanosecond range, which is essential for protecting circuits from rapid voltage spikes.

Conclusion:

The SMAJ15CA from Bourns, Inc. is a robust and reliable transient voltage suppressor diode that provides essential protection for electronic circuits against voltage transients. Its combination of high power handling capability, low leakage current, and wide operating temperature range makes it a versatile choice for a variety of applications in the electronics industry.
