ESD protection diodes are similar to Zener diodes in that they’re designed to conduct at a certain voltage level. Common schematic symbols for these TVS diodes are shown in Figure 2 .

This differs from the circuit shown in Figure 1 by not only the value of the limiting R but also the 2.2kΩ protects from voltages above +Vs. This is an example of the intricacies that must be fully ...

For instance, if you’re designing a level shifting circuit, using an input on an IC that’s only protected by a Zener/FET ESD protection structure to ground will be preferable/advantageous ...

New generations of portable products are increasingly sensitive to damage from Electrostatic Discharge (ESD) voltage as newer integrated circuit (IC) technologies employ smaller geometries and lower ...

Take a look at ESD diodes, where and how to add them, where to ... can give a GPIO – throw in a low-value series resistor too, if you’re generous. If you’re doing, say, a RP2040 circuit, ...

(Schematic drawn by BSCH3V) ESD diodes are internal. The upper diode is forward-biased when V IN is greater than V CC plus the diode’s threshold voltage, ...

AVX Corporation , a leading manufacturer and supplier of passive components and interconnect solutions, has released a new series of bidirectional ESD suppression diodes that combine the latest in ...

The Impulse TSMC .13u ESD diode was made to provide ESD discharge paths when integrating third party IP in an integrated circuit design for total ESD protection. The Impulse ESD diode has been ...

The possible ESD discharge path starts at I/O pad A, goes through a pull-up diode, a power clamp, the B2B diode, the ground bus VSS B, a pull-down diode, and eventually ends at I/O pad B. Not only ...

Nexperia has introduced the industry’s first ESD diodes designed to protect 48 V automotive data communications networks against the destructive effects of electrostatic discharge (ESD) events. ESD ...

“Until now, automotive equipment manufacturers lacked suitable ESD protection solutions specifically designed for 48V data lines,” claimed Nexperia head of protection devices Alexander Benedix. “As a ...
