84,045 productsAbout TVS Diodes
TVS (Transient Voltage Suppressor) Diodes are active circuit protection devices designed to safeguard sensitive integrated circuits from destructive overvoltage transients, electrostatic discharge (ESD) events, and lightning-induced surges. Operating by clamping voltage spikes to a safe level within picoseconds, TVS diodes divert heavy surge currents directly to ground, preventing die breakdown in processors and communication transceivers.
TVS diodes are critical components in automotive Ethernet, USB Type-C ports, HDMI interfaces, and industrial sensor lines. They are available in unidirectional and bidirectional configurations. Key selection specifications include reverse standoff voltage (VRWM), breakdown voltage (VBR), clamping voltage (VC at peak current), peak pulse power dissipation (PPK, e.g., 400W, 600W, 1500W), junction capacitance (critical for high-speed data lines to prevent signal distortion), and package footprints (SMD like SOD-323, SMA, SMB, SMC, and arrays).
