General
The DF2B20M4SL is a bidirectional TVS diode with high VRWM(18.5V) designed to protect high speed line or differential signal line
from the damage caused by ESD and other transients voltage. This TVS diode can protect the latter part well by the low dynamic
resistance, improve the system reliability level by the high VESD performance. It is optimum for antennal application such as NFC
for the low capacitance performance. And the small package size (0.62 mm × 0.32 mm) is ideal for high-density mounting.
