The ESD9B5.0ST5G is a 2-pin, 5V bidirectional ESD protection diode from ON Semiconductor. It is designed to protect voltage sensitive components from electrostatic discharge (ESD). The ESD9B5.0ST5G has excellent clamping capability, low leakage, and fast response time, providing best-in-class protection for designs that are exposed to ESD.

The ESD9B5.0ST5G is housed in a small SOD-923 package, making it ideal for use in portable applications where board space is limited. It is also RoHS compliant and has a moisture sensitivity level of 1.

Features and Benefits

Bidirectional ESD protection for positive and negative pulses Excellent clamping capability (12.5V) Low leakage current (1uA) Fast response time (less than 1ns) Small SOD-923 package RoHS compliant Moisture sensitivity level of 1 Applications

Portable electronics (cell phones, MP3 players, digital cameras, etc.) Computer peripherals Telecommunications equipment Industrial control systems Automotive electronics Typical Circuit Diagram

Usage Notes

The ESD9B5.0ST5G should be connected in parallel with the circuit that is being protected. The input and output pins of the ESD9B5.0ST5G should be connected to the corresponding pins of the circuit being protected.

The ESD9B5.0ST5G is designed to protect against ESD events up to 8kV. However, it is important to note that the ESD protection capability of any device will degrade over time. Therefore, it is recommended to replace ESD protection devices periodically, especially in applications where they are exposed to frequent ESD events.

Conclusion

The ESD9B5.0ST5G is a high-performance ESD protection diode that is ideal for use in a wide range of applications. It offers excellent clamping capability, low leakage current, and fast response time in a small SOD-923 package.
