SMAJ48CA

The SMAJ48CA 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 inductive load switching.

Key Features:

1. Voltage Rating: The SMAJ48CA has a breakdown voltage of approximately 48 volts, making it suitable for applications that require clamping of voltage levels around this threshold. It is designed to activate and conduct when the voltage exceeds this level, thereby protecting downstream components.

2. Power Dissipation: The device can handle a peak power dissipation of up to 600 watts, which allows it to absorb significant energy from transient events without failing. This high power rating is crucial for applications where large voltage spikes are expected.

3. Package Type: The SMAJ48CA is housed in a DO-214AA (SMA) package, which is a surface-mount device (SMD) configuration. This package is compact, making it suitable for space-constrained applications while providing good thermal performance.

4. Response Time: The response time of the SMAJ48CA is extremely fast, typically in the nanosecond range. This rapid response is essential for effectively clamping voltage spikes before they can damage sensitive components.

5. Temperature Range: The operating temperature range for the SMAJ48CA is typically from -55°C to +150°C, allowing it to function reliably in a wide variety of environmental conditions.

6. Capacitance: The device features low capacitance, which minimizes the impact on signal integrity in high-speed data applications. This characteristic is particularly important in communication and data processing circuits.

7. Applications: The SMAJ48CA is commonly used in various applications, including automotive electronics, telecommunications, consumer electronics, and industrial equipment. It is ideal for protecting circuits in power supplies, data lines, and other sensitive electronic components.

8. Compliance and Standards: The SMAJ48CA is designed to meet various industry standards for reliability and performance, making it a trusted choice for engineers and designers looking for robust transient protection solutions.

Summary:

In summary, the SMAJ48CA from Littelfuse Inc. is a high-performance transient voltage suppressor diode that offers excellent protection against voltage transients. With its high power dissipation capability, fast response time, and compact packaging, it is well-suited for a wide range of electronic applications where reliability and performance are critical.
