The PESD2CAN,215 by Nexperia is a specialized ESD protection diode for Controller Area Network (CAN) bus lines in automotive applications. Packaged in a compact SOT23 form, it is designed to safeguard sensitive electronic components against the damaging effects of ElectroStatic Discharge (ESD) and other transient voltage spikes. This diode features a maximum peak pulse power of 230W for transient events and a low clamping voltage of 41V at a peak pulse current of 5A, ensuring effective protection during surge events.
Key to its performance is the ultra-low leakage current of less than 1nA, minimizing power loss when the device is in standby. The diode's ability to withstand ESD events up to 30kV, coupled with compliance to stringent automotive quality standards (AEC-Q101), makes it an ideal choice for protecting the integrity of automotive CAN bus systems against electrical transients.
ESD Protection Diodes
Electrostatic Discharge (ESD) protection diodes are designed to protect sensitive electronic components from the sudden and immediate discharge of static electricity. ESD can cause immediate damage to electronic circuits or degrade them over time, leading to failure. These diodes are placed across data lines or other susceptible circuits to clamp voltage spikes caused by ESD, thus preventing damage.
When selecting ESD protection diodes, engineers should consider factors such as the working voltage of the circuit, clamping voltage, peak pulse current, and the specific ESD protection standards the component complies with. The package size and configuration are also important considerations, especially in compact designs or where multiple lines need protection. For applications with stringent quality requirements, such as automotive or industrial applications, selecting components that are qualified to relevant standards is critical.
In addition to protecting against ESD, these diodes can also safeguard against other transient voltage events, making them versatile components in ensuring the reliability and longevity of electronic systems. Understanding the specific needs of the application, including the environment and the nature of the data lines to be protected, is crucial in choosing the right ESD protection solution.
