Automotive Bi-directional ESD Protection Diode in SOT-23 package

2025-04-11

Product News

The TESDA24VB28P2CX is Bidirectional ESD-rated clamping cell to protect power interfaces, control line, or low speed data line in an electronic system. The capacitance CJ must be less than 100 pF to maintain signal integrity at the maximum data rate of 20 kbit/s. To minimize the total impact of the diode on the system, CJ should be smaller than 30 pF.  It has been specifically designed to protect sensitive electronic components connected to power and control lines from over-voltage damage caused by Electrostatic Discharging (ESD) and Lightning.
