It provides ±16 kV IEC 61000-4-2 ESD immunity, ultra-low 0.29 pF typical load capacitance, <0.05 μA reverse leakage at 3.3 V, and clamps transients to ≤15 V at 2.5 A peak pulse current. It is used in USB 3.0, HDMI, and Thunderbolt signal lines.
For engineers reviewing the VBUS03B1-SD0-G4-08 datasheet, VBUS03B1-SD0-G4-08 pinout, VBUS03B1-SD0-G4-08 application, or VBUS03B1-SD0-G4-08 equivalent, key selection criteria include clamping voltage under 2.5 A, sub-0.4 pF capacitance at 3.3 V bias, CLP0603 footprint compatibility, and ±3.3 V working range for high-speed serial interface protection.
Technical Context
The VBUS03B1-SD0-G4-08 implements a silicon-based bidirectional TVS structure with symmetrical breakdown (VBR = 6.0–10 V) and low dynamic resistance (RDYN = 1.14 Ω). Its CLP0603-2L package features short internal leads and minimal parasitic inductance, enabling fast response to ESD transients with low overshoot.
It operates within ±3.3 V reverse stand-off range and delivers stable clamping performance across temperature (−55 °C to +150 °C), with verified 45 W peak pulse power handling per IEC 61000-4-5 (8/20 μs).
Key Specifications
