Ultra Low Capacitance DF2B5M4ASL and DF2B6M4ASL ESD Protection Diodes

Toshiba's ESD diodes feature minimal insertion loss in high-speed designs

Image of Toshiba's DF2B5M4ASL, L3F and DF2B6M4ASL, L3F ESD diodes Toshiba's ultra-low capacitance ESD protection diodes support high-speed communication standards such as Thunderbolt® 3, HDMI® 2.1, and USB 3.1. The DF2B5M4ASL supports a maximum operating peak reverse voltage of 3.6 V, while the DF2B6M4ASL supports a voltage of 5.5 V. Tablets, laptops and game consoles minimize the transfer time of video data or large files by using 10 Gbps or 48G bps high-speed communication standards. With increasing miniaturization of controller ICs used in these high-speed communication applications, ESD tolerance is decreasing, necessitating enhanced measures to deal with ESD and surges from connectors. No ESD protection can lead to serious failures such as communication errors and file corruption.

Parts connected to high-speed communication lines can greatly affect the signal; passive components on the printed circuit board, such as capacitors and resistors, can distort the signal waveform. The DF2B5M4ASL and DF2B6M4ASL reduce these effects with lower capacitance for high-speed communications. In addition, by optimizing the process, the product can achieve a capacitance of 0.15 pF (typ), which is about 25% lower than most current products. This contributes to the stability of circuits used for high-speed communication.

Low capacitance minimizes insertion loss. This performance has the highest ESD immunity in its class. This series of ESD protection diodes is available in an industry standard SL2 (SOD-962) package (commonly referred to as 0402). The advantageous features of the DF2B5M4ASL and DF2B6M4ASL protect high-speed data lines with high antistatic properties and low capacitance.
