Infineon Technologies released a new TVS (transient voltage suppression) diode to protect Gigabit Ethernet interfaces from potential damage due to voltage surge or electrostatic discharge (ESD) events.
The new TVS3V3L4U diode features exceptionally low capacitance to meet the high signal integrity requirements of this application, while delivering the robustness and clamping voltage characteristics typical of Infineon’s broad portfolio of circuit protection devices.
The device features surge absorption capability of 20 A without signs of degradation, meeting requirements of IEC61000-4-5, and high ESD absorption capability of ±30 kV that exceeds IEC61000-4-2. It has very low clamping voltages of VCL <8 V for surge currents of 20 A (8/20 μs).
Dynamic resistance is low at RDYN= 0,15 Ω I/O-GND (according to surge standard IEC61000-4-5) and 0,09 Ω GND-I/O (ESD standard IEC61000-4-5) which enables extremely low clamping voltages of VCL <6 V for 16 A TLP current, equivalent to 8 kV ESD to IEC61000-4-2.
Capacitance is typically a low 2,9 pF I/O-GND and 1,5 pF I/O-I/O to meet the signal integrity requirements of Gigabit Ethernet. The diode is supplied in an industry-standard SC74 leaded array package, with one component replacing up to four devices. It is tailored for protection of signal lines operating up to a maximum voltage of 3,3 V.
