Infineon BCR142E6327: High-Performance ESD Protection Diode in SOT-23 Package

In the realm of modern electronics, safeguarding sensitive integrated circuits (ICs) from electrostatic discharge (ESD) is a critical design challenge. The Infineon BCR142E6327 stands out as a premier solution, offering robust protection in a compact SOT-23 package. This device is engineered to provide superior ESD immunity, making it an indispensable component for a wide range of applications, from consumer electronics to industrial systems.

The BCR142E6327 is specifically designed as a low-capacitance ESD protection diode, featuring a typical capacitance of just 2.5 pF. This minimal loading effect ensures that signal integrity is preserved, even in high-speed data lines such as USB 2.0, HDMI, or antenna connections. Its primary function is to clamp hazardous voltage transients caused by ESD events, diverting excess current away from vulnerable circuits and thereby preventing latch-up or permanent damage. With compliance to the stringent IEC 61000-4-2 standard, it can withstand ESD strikes up to ±30 kV (air discharge) and ±20 kV (contact discharge), offering reliable defense in the most demanding environments.

Housed in a SOT-23 surface-mount package, the BCR142E6327 combines high performance with exceptional space efficiency. This small form factor is ideal for densely populated PCBs where board real estate is at a premium. Additionally, its low leakage current (typically less than 50 nA) minimizes power loss, enhancing overall system efficiency. The device is also characterized by its fast response time, reacting to ESD pulses in nanoseconds to ensure immediate protection.

Typical applications include protecting ports, interfaces, and RF modules in mobile devices, computing peripherals, automotive electronics, and communication infrastructure. By integrating the BCR142E6327, designers can significantly improve product reliability and compliance with international ESD regulations.
