With the advent of the Internet of Things era, Gigabit Ethernet has developed into the mainstream network technology. While enjoying the convenience brought by fast network, we also need to protect it from electrostatic discharge. ULC33CP8 is specially designed by Lei Mao to protect Gigabit Ethernet interface from electrostatic discharge. This material can also completely replace UCLAMP3312T of SEMTECH, and at the same time, it has the advantages of fast delivery, better price and better electrical performance. The comparison is as follows:

Leiditech ULC33CP8 parameters:

IEC61000-4-2 (ESD) ±30kV (air), ±30kV (contact)

Package: DFN2010 (2.0*1.0mm)

VRWM: 3.3V

IPP：13A (8/20μs)

VC：7V

Ppp: 200W

Ultra-low capacitance: 0.4 PF

Suitable for: 10/100/1000 Ethernet, integrated magnet /RJ-45 connector, LAN/WAN equipment, security camera, industrial control, peripheral equipment, notebook/desktop computer.

Semtech UCLAMP3312T parameters:

IEC61000-4-2 (ESD) ±30kV (air), ±30kV (contact)

Package: SLP2010N8T (2.0*1.0mm)

VRWM: 3.3v

IPP：10A (8/20μs)

VC：5.6V

Ppp: 100W

Low capacitance: 1.3 PF

Suitable for: 10/100/1000 Ethernet, integrated magnet /RJ-45 connector, LAN/WAN equipment, security camera, industrial control, notebook/desktop computer.

To judge the advantages and disadvantages of ESD, see the following parameters:

1. Anti-static ability, both of which can reach the current highest anti-static level of+-30kV.

2. Looking at the anti-surge IPP capability of ESD, under the 8/20us test condition, the ULC33CP8 IPP of LEIDITECH is 13A, and that of Semtech is 10A. It can be seen that the chip of Leiditech in Shanghai Leimao has a higher anti-surge rating.

3. Look at the capacitance. LEIDITECH's ULC33CP8 is ultra-low capacitance, only 0.4pf, and Semtech is 1.3pf.

LEIDITECH, a brand of Leimao, is a professional supplier of lightning protection and anti-static components and solutions.
