ONSEMI ESD9L50ST5G ESD Protection Diode

The ESD9L50ST5G is an ultra-low capacitance ESD protection diode designed for high-frequency applications. It effectively safeguards sensitive components during ESD and transient events, featuring a low capacitance of 0.5 pF, fast response time under 1 ns, and low leakage current. Suitable for USB 2.0 high-speed and antenna lines, it offers excellent clamping voltage, compact size (0.039” x 0.024”), and is RoHS compliant. Additional features include a stand-off voltage of 3.3 V, leading to its use in space-constrained, high-speed electronic designs.
