onsemi 1-Element Bi-Directional TVS Diode 0.3 W, 2-Pin SOD-923 ESD9B3.3ST5G

The onsemi ESD9B3.3ST5G is a 1-element bi-directional transient voltage suppression (TVS) diode engineered to provide low capacitance electrostatic discharge (ESD) protection for delicate electronic components. It features a single diode configuration for efficient and reliable suppression of transient voltage spikes, making it ideal for protecting sensitive circuits in automotive, industrial, and consumer electronics applications.

This device is surface mounted in a compact 2-pin SOD-923 package with minimal height of 0.4 mm, length of 0.85 mm, and width of 0.65 mm, facilitating space-constrained PCB designs. The diode offers a minimum breakdown voltage of 5 volts and a maximum reverse stand-off voltage of 3.3 volts, providing effective bidirectional voltage surge protection. Its peak pulse power dissipation of 0.3 watts and peak pulse current capacity of 10.5 amperes ensure robust tolerance to transient voltage events.

The clamping voltage of 10.5 volts protects downstream circuitry by limiting voltage spikes, while the device maintains exceptionally low reverse leakage current at 100 nA, minimizing power losses during normal operation. It complies with the automotive standard AEC-Q101, indicating suitability for automotive-grade electronics requiring high reliability and stringent quality standards.

Operating reliably over a wide temperature range from -55°C to 150°C, the ESD9B3.3ST5G is well-suited for rigorous industrial, automotive, and commercial electronics environments. Its low capacitance design makes it particularly useful in high-speed data lines and RF circuits where signal integrity is critical. Typical applications include power supplies, data interfaces, communication equipment, and PCB level ESD protection.

Features of this diode include an effective low-capacitance ESD protection array and easy PCB mounting due to its surface mount package. This device supports protection against voltage transients caused by inductive load switching, lightning-induced surges, and electrostatic discharge.
