TVS - Diodes provide surge protection for sensitive electronic components against surge transients such as ESD and lightning. The P4SMA130CA is a unidirectional 2-line TVS diode designed to protect in-line data line like those used in computer and automotive applications from damage caused by overvoltage conditions. It is designed to protect data lines up to +/-25V at data-rates up to 400Mbps and is enhanced to ensure fast response to high-energy surges such as ESD.

The working principle of the P4SMA130CA is based on the suppression of destructive surge transients. When a transient voltage is detected, the diode switches to the on-state quickly and diverts the current away from the protected line. This prevents the surge from damaging the sensitive devices connected to the lines. The diode then quickly returns to the off state as the transient dissipates, allowing the system to continue operating as normal.

The P4SMA130CA is ideal for in-line data protection applications in industrial, consumer and automotive electronics where it is desired to ensure data integrity and reliable communication. It can be used in a wide variety of products including computer systems and peripherals, office equipment, cell phones, digital audio, in-car entertainment systems, Bluetooth, USB and other portable electronics. It has an extended temperature range so that it can reliably operate in extreme temperatures and environments.

The P4SMA130CA has high surge capabilities, excellent clamping performance and fast response time. It is available in two package styles: the SMA package for SMT applications and the DO-214AC package for through-hole applications. The P4SMA130CA can withstand peak pulse currents up to 8A and is designed to divert transient voltages from 0V to 25V, providing excellent protection. The diode also offers a low on-state resistance (0.35 ohms typical) for minimal signal attenuation.

The P4SMA130CA is designed to meet or exceed Automotive Electronics Council AEC Q101-002 requirements and offers superior ESD protection. It is easy to use and cost-effective, making it ideal for a variety of applications. Furthermore, it is RoHS compliant and is available in standard and custom configurations to accommodate varied requirements.
