TDK’s new compact TVS diodes feature parameters matched to USB-C ports and other high-speed interfaces. The B74111U0033M060 and B74121U0033M060 devices offer capacitance values of 0.48 and 0.65pF at 1MHz, respectively, which means signal integrity is not compromised. The clamping voltages are 3.8 or 3.9V with an ITLP of 8A.
The devices are designed for ESD discharge voltages of up to 15kV. The diodes are manufactured in WLCSP 01005 and WLCSP 0201 packages with heights of 100 and 150µm respectively. This means the diodes can also be integrated into USB-C SIP modules.
The B74111U0055M060 and B74121U0055M060 types, with maximum DC voltages up to 5.5V, suit conventional USB2.0 data bus of USB-C (D+/D-). Clamping voltages are 3.9 and 4.0V with an ITLP of 8A. They are also designed for a high ESD discharge voltage up to 15kV.
