SM6T100AHE3/52 Application Field and Working Principle

Transient Voltage Suppressor Diode (TVS) is a diodes devised for the protecting of electronic circuits from transients over-voltages, such as the voltage caused by load dumps, induced radiations and electrostatic discharge. TVS diodes are designed for surge protection with low leakage current and low capacitance. One example of such diode is the SM6T100AHE3/52.

SM6T100AHE3/52 is a low-leakage current (Ileakage : < 0.1uA), ultra-small and ultra-low capacitance (C : 0.12pF typ.) TVS Diode Device, designed using a PNP structure for ESD (Electrostatic Discharge) and EFT (Electric Fast Transients) protection of various systems.

The application field of SM6T100AHE3/52 is quite wide and it contains automotive systems, communications systems, medical systems and network equipment. SM6T100AHE3/52 is the preferred diode for applications that require robust over-voltage protection with high power dissipation, low-capacitance, and low-leakage current.It is an ideal solution for device performance and protecting from the destructions of over-voltage transients.

The working principle of TVS diode is based on the fact that when an over-voltage arises, a diode can be quickly switched from a high-resistance state (off) to a low-resistance state (on) to clamp the voltage across the device. The working principle of SM6T100AHE3/52 is same diodes. The diode is accurately designed to have an avalanche break down voltage VBR of 6 V and can withstand repetitive peak pulse currents up to 100 A (Ippm) with an 8/20uS Pulse Waveform. The reverse stand-off voltage (Vrwm) is 5.5V with a maximum clamping voltage for repetitive transient voltage (Vc max) of 11.7V.

In conclusion, SM6T100AHE3/52 is an example of TVS diode suitable for a large variety of applications. The diode can be used for the protection from transients over-voltages and it offers excellent protection capability with low leakage current and low capacitance. SM6T100AHE3/52 is the ideal choice for device performance and protection from the destructions of over-voltage transients.
