RCLAMP0512TQTCT Description

Short technical summary and product information.

The RCLAMP0512TQTCT, part of Semtech's RClamp family, is a low capacitance RailClamp 2-line surge and ESD protection device. It integrates low capacitance steering diodes with a snap-back TVS to provide high surge capability while minimizing clamping voltage. Key specifications include a 5V reverse stand-off voltage, 8.5V maximum clamping voltage at 20A (8/20µs), and ultra-low typical dynamic resistance of 0.075Ω. The device offers 30kV ESD withstand per IEC 61000-4-2 (air and contact) and 4kV EFT immunity. Junction capacitance is a maximum of 3pF, making it suitable for high-speed data lines such as Ethernet and USB 2.0. The device is qualified to AEC-Q100 Grade 1, operating over -40°C to +125°C. It is housed in a compact SGP1006N3T surface mount package measuring 1.0x0.6x0.4mm with NiAu lead finish and UL 94V-0 flammability rating. Packaging is Tape and Reel. Applications include automotive electronics, industrial equipment, integrated magnetics/RJ-45 connectors, and 10/100/1000 Ethernet.
