Infineon ESD5V3U2U-03LRHE6327: Ultra-Low Capacitance ESD Protection Diode

In the realm of modern electronics, protecting sensitive circuits from electrostatic discharge (ESD) is paramount. The Infineon ESD5V3U2U-03LRHE6327 stands out as a premier solution, specifically engineered to provide robust ESD protection while maintaining signal integrity in high-speed data lines. This ultra-low capacitance ESD protection diode is designed to meet the stringent demands of today’s advanced applications, from USB 3.0 and HDMI to high-frequency RF interfaces.

One of the most critical features of this diode is its ultra-low capacitance of just 0.3 pF typical. This minimal capacitance is essential for high-speed data lines, where any additional capacitive load can distort signals, leading to data corruption and reduced performance. By keeping capacitance exceptionally low, the ESD5V3U2U-03LRHE6327 ensures that signal integrity is preserved, even at data rates exceeding 5 Gbps.

The device offers outstanding ESD protection, compliant with the stringent IEC 61000-4-2 standard. It can withstand ESD strikes up to ±8 kV (contact discharge) and ±15 kV (air discharge), providing a reliable safeguard for sensitive ICs. The low clamping voltage of the diode quickly diverts ESD transients away from the protected circuit, minimizing the risk of damage.

Housed in a compact ultra-small SOD-323 (SC-76) package, this diode is ideal for space-constrained PCB designs. Its minimal footprint allows for high-density layouts without compromising protection performance. Additionally, the device exhibits low leakage current and excellent thermal stability, ensuring reliable operation across a wide temperature range.

The ESD5V3U2U-03LRHE6327 is particularly suited for applications such as smartphones, tablets, wearables, and IoT devices, where both performance and space are critical. It is also RoHS compliant and halogen-free, aligning with modern environmental standards.

ICGOO FIND: The Infineon ESD5V3U2U-03LRHE6327 is an exceptional choice for designers seeking to enhance ESD robustness in high-speed circuits without sacrificing signal quality. Its ultra-low capacitance, high ESD immunity, and miniature form factor make it a top-tier component for protecting next-generation electronics.
