Infineon ESD221U102ELE6327XTMA1: High-Performance TVS Diode for Superior ESD Protection

In the realm of modern electronics, safeguarding sensitive components from electrostatic discharge (ESD) and transient voltage events is paramount. The Infineon ESD221U102ELE6327XTMA1 stands out as a state-of-the-art TVS (Transient Voltage Suppression) diode specifically engineered to deliver robust ESD protection in a compact and efficient package. This device is designed to meet the stringent demands of today's high-speed data interfaces and portable electronics, where even minor voltage spikes can cause catastrophic failures.

One of the key strengths of the ESD221U102ELE6327XTMA1 is its exceptionally low clamping voltage. This characteristic ensures that during an ESD event, the voltage seen by the protected IC is minimized, thereby significantly reducing the risk of damage. With a working voltage of 2.2V, it is ideally suited for protecting low-voltage supply rails and high-speed data lines commonly found in applications such as USB 3.0/3.1, HDMI, and portable devices.

The diode features a bidirectional configuration, providing protection against both positive and negative transient voltage surges. This makes it an incredibly versatile solution for a wide array of circuit designs. Housed in an ultra-small SOT-523 (SC-79) package, it offers superior board space savings without compromising on performance, a critical factor for the increasingly miniaturized world of consumer electronics.

Furthermore, this component complies with the stringent IEC 61000-4-2 (Level 4) standard, offering protection up to ±8kV contact discharge and ±15kV air discharge. This guarantees reliability in the most challenging environments. Its low leakage current and minimal capacitance ensure that signal integrity remains uncompromised, making it perfect for high-speed data applications where maintaining signal fidelity is non-negotiable.

ICGOODFIND: The Infineon ESD221U102ELE6327XTMA1 is a premier choice for designers seeking reliable, high-performance ESD protection. Its combination of low clamping voltage, minimal footprint, and compliance with international standards makes it an indispensable component for ensuring the longevity and reliability of sensitive electronic circuits.
