Overview
As electronic products continue to evolve towards lower power consumption, miniaturization, and higher integration, more and more electronic systems are adopting low-voltage power supply solutions.
3.3V and 5V power supply systems are common in electronic devices, while 2.5V is increasingly being used in power interfaces and I/O interfaces.
2.5V low-voltage systems are widely used in:
- Smartphones, tablets, digital cameras
- Game consoles, MP3 players, e-readers
- GPS navigators, Bluetooth headsets, smartwatches, smart bracelets
- Health monitoring devices (heart rate monitors, blood pressure monitors, medical endoscopes)
- Smart home appliances (microwave ovens, ovens, coffee makers, printers, monitors)
- Industrial sensors, charging stations, and IoT devices
These devices typically contain highly integrated MCUs, SoCs, sensors, and high-speed communication interfaces, placing higher demands on ESD (electrostatic discharge) protection.
I. Why are ESD protection">2.5V ESD protection devices becoming increasingly widely used?
1. Low-voltage chips are more sensitive to static electricity.
As semiconductor manufacturing processes continue to shrink, the internal structure of chips becomes increasingly precise, and the thickness of the gate oxide layer decreases, reducing the chip's ability to withstand transient high-voltage shocks.
Although electrostatic discharge (ESD) is extremely short-lived, it can instantaneously generate:
- Thousands of volts of voltage
- Tens of amperes of current
- A rapid rise time on the nanosecond scale
When static electricity enters electronic devices through external interfaces, it can cause:
- Internal IC breakdown
- Data corruption
- System restart
- Reduced product lifespan
Therefore, in 2.5V low-voltage circuits, ESD protection devices with low operating voltage and fast response capabilities need to be selected.
2. Leakage current impacts low-power design
Smart wearable devices, wireless devices, and portable products are typically battery-powered. Excessive leakage current in ESD devices can increase standby power consumption and reduce battery life.
Therefore, low leakage current is an important indicator for 2.5V applications.
