Frequently Asked Questions
What is the clamping voltage of VESD12C1-02VHG3-08 and how does it protect downstream ICs?
The VESD12C1-02VHG3-08 clamps transient overvoltages to a maximum of 22.7 V during an ESD event, while its 14.7 V nominal breakdown voltage ensures the diode activates promptly to divert surge current. This clamping behavior limits the voltage seen by connected ICs, preventing gate-oxide damage or latch-up in USB controllers and HDMI receivers operating at 12 V.
Why is the 26 pF diode capacitance of VESD12C1-02VHG3-08 critical for high-speed interface protection?
At 26 pF minimum capacitance, the VESD12C1-02VHG3-08 adds minimal loading to high-speed data lines such as USB 2.0 and HDMI, where excessive capacitance degrades signal rise times and introduces jitter. Lower capacitance is especially important on lines carrying data at hundreds of megabits per second, maintaining signal integrity while still providing robust ESD suppression.
How does the SOD-523 package of VESD12C1-02VHG3-08 benefit PCB layouts in portable devices?
The SOD-523 package measures approximately 1.6 mm x 0.8 mm, one of the smallest available footprints for TVS diodes. This compact size allows VESD12C1-02VHG3-08 to be placed directly adjacent to connector pads on smartphone and tablet PCBs, minimizing the stub length between the ESD device and the protected pin and improving transient suppression effectiveness at 12 V working voltage.
What is the factory lead time for VESD12C1-02VHG3-08 and how should supply chain teams manage it?
The VESD12C1-02VHG3-08 carries a factory lead time of 8 weeks. For high-volume consumer electronics programs assembling millions of units, procurement teams should maintain at least a 10-week safety stock buffer and place blanket orders in advance, especially given the compact SOD-523 diode's popularity across USB and HDMI ESD protection designs where demand can spike rapidly.
