They can also be used to protect the USB Type-C charging lines (VBUS = 5V to 20V) that will be widely used in the future.
The diodes are based on Toshiba’s proprietary Zener diode process. This has lowered dynamic resistance to 80% of existing parts, while high peak pulse current ratings are over 30 times greater. Each diode in the series has an ESD rating of 30kV.
There will be six diodes in the DF2SxxP2 series, offering power supply line voltage ratings of 5V, 12V and 20V.
Each voltage rating is available in either a compact, low-profile SOD-963 (CST2C) or a standard SOD-323 (USC) package.
Package dimensions are 1.6mm x 0.8mm x 0.48mm and 2.5mm x 1.25mm x 0.9mm respectively.
