It has the following three characteristics:

1, the diode of the instantaneous voltage suppressor is added to the signal and power line, which can prevent the microprocessor or single-chip computer from rushing due to instantaneous generation, such as static electricity. Fault caused by discharge effect, AC power surge, switching power supply noise.

2. Electrostatic discharge effect can release pulses above 10000V and 60A, lasting 10ms; And universal TTL

3. The diode of the transient voltage suppressor is placed between the signal line and the ground, which can avoid unnecessary noise shadows on the data and control bus.
