PESD0402-140

The PESD0402-140 is a specialized component manufactured by Littelfuse Inc., designed primarily for ESD (Electrostatic Discharge) protection in electronic circuits. This device is particularly useful in safeguarding sensitive components from voltage spikes caused by electrostatic discharge, which can occur during handling or operation.

Key Features:

1. Package Type: The PESD0402-140 is housed in a compact 0402 (1.0 mm x 0.5 mm) surface-mount package, making it suitable for applications where space is at a premium. This small footprint allows for easy integration into densely populated circuit boards.

2. ESD Protection: The device is designed to protect against ESD events up to ±30 kV contact discharge and ±30 kV air discharge, adhering to the IEC 61000-4-2 standard. This high level of protection ensures that sensitive components, such as integrated circuits and data lines, are shielded from potentially damaging voltage spikes.

3. Low Capacitance: The PESD0402-140 features low capacitance (typically around 0.5 pF), which is crucial for high-speed data lines. This low capacitance helps maintain signal integrity, minimizing any impact on the performance of high-frequency signals.

4. Working Voltage: The device has a maximum working voltage of 5 V, making it suitable for various low-voltage applications, including USB, HDMI, and other communication interfaces.

5. Clamping Voltage: The clamping voltage is relatively low, ensuring that during an ESD event, the voltage does not exceed safe levels for the protected components. This characteristic is essential for preventing damage during transient events.

6. Applications: The PESD0402-140 is ideal for use in consumer electronics, telecommunications, automotive electronics, and industrial applications. It is commonly used in devices such as smartphones, tablets, laptops, and other portable electronics where ESD protection is critical.

7. RoHS Compliant: The component is compliant with RoHS (Restriction of Hazardous Substances) regulations, ensuring that it is free from harmful substances and environmentally friendly.

Summary:

In summary, the PESD0402-140 from Littelfuse Inc. is a highly effective ESD protection device that combines a compact size with robust performance characteristics. Its low capacitance, high ESD protection level, and suitability for various applications make it an excellent choice for engineers looking to enhance the reliability and durability of their electronic designs.
