Transient Voltage Suppressor (TVS) diodes clamp voltage spikes from ESD, lightning, load switching, and inductive kickback — protecting sensitive ICs and communication lines in automotive ECUs, industrial I/O interfaces, telecom equipment, and consumer electronics. Our TVS inventory includes unidirectional and bidirectional single-channel and array devices from Littelfuse, Vishay, STMicroelectronics, ON Semiconductor, and Nexperia, covering breakdown voltages from 5V to 600V, power ratings from 400W to 30kW, and packages from SOD-323 and SMA to DO-201 and axial leaded.
High-power TVS devices for telecom and industrial line protection are frequently constrained, especially in DO-15 and SMBJ/SMCJ packages. Welllinkchips stocks commonly allocated TVS part numbers and can source obsolete or long lead-time variants needed for repair and legacy system maintenance.
