SMCJ30CA

The SMCJ30CA is a part of the SMCJ series of transient voltage suppressor (TVS) diodes manufactured by Littelfuse Inc. This component is designed to protect sensitive electronic equipment from voltage spikes and transients, which can occur due to lightning strikes, electrostatic discharge (ESD), or other electrical disturbances.

Key Features:

1. Voltage Rating: The SMCJ30CA has a breakdown voltage of approximately 30 volts, making it suitable for applications that require clamping of voltage spikes around this level. The device is designed to handle transient voltages effectively while ensuring that the normal operating voltage of the circuit remains unaffected.

2. Power Dissipation: The SMCJ30CA can handle a peak power dissipation of up to 600 watts for a short duration, which is crucial for absorbing high-energy transients without failing. This capability ensures that the device can protect downstream components from damage.

3. Package Type: The SMCJ30CA is housed in a DO-214AB (SMC) package, which is a surface-mount device (SMD) configuration. This package is designed for efficient thermal management and provides a compact footprint, making it suitable for various PCB layouts.

4. Clamping Voltage: The clamping voltage of the SMCJ30CA is specified to be around 40.5 volts at a peak pulse current of 10A, which indicates how much voltage the device will allow to pass through during a transient event before it starts to clamp and protect the circuit.

5. Response Time: The SMCJ30CA features a fast response time, which is essential for protecting sensitive components from fast-rising transients. This quick response helps to minimize the risk of damage to the connected devices.

6. Temperature Range: The operating temperature range for the SMCJ30CA is typically from -55°C to +150°C, allowing it to function reliably in a variety of environmental conditions.

7. Applications: This TVS diode is commonly used in automotive electronics, telecommunications, consumer electronics, and industrial applications where overvoltage protection is critical. It is particularly useful in circuits that interface with external connections, such as power lines or communication lines.

8. Compliance and Standards: The SMCJ30CA is designed to meet various industry standards for reliability and performance, making it a trusted choice for engineers looking to implement robust protection solutions in their designs.

Conclusion:

The SMCJ30CA from Littelfuse Inc. is a reliable and efficient transient voltage suppressor diode that provides essential protection for electronic circuits against voltage spikes. Its combination of high power handling, fast response time, and compact packaging makes it an ideal choice for a wide range of applications where overvoltage protection is necessary.
