Compact bi-directional ESD diode for portable designs
As the DF2B7ASL features a snapback characteristic, it can provide low clamping voltages, which together with the low dynamic resistance of the diode ensures superior protective performance to safeguard semiconductors ICs against static electricity. With a package footprint under 1mm2, it is aimed at interfaces in smart phones, wearables and other battery powered equipment.
While featuring low dynamic resistance of just 0.2Ω and a low clamping voltage (VC) of 11V at 5V signal lines (VRWM ≤ 5.5V), the DF2B7ASL still offers an electrostatic discharge voltage rating of +/-30kV in accordance with IEC61000-4-2 (contact discharge).
Taking the need for small footprints into consideration, the diodes are supplied in a SOD-962 (SL2) package with a board mounting footprint of 0.32mm x 0.62mm.
