How the SM712-02HTG Works

TVS diodes work by shunting transient voltage spikes away from sensitive electronic components. When a transient overvoltage event occurs, the TVS diode conducts current, diverting the excess voltage away from the protected components. Once the transient overvoltage event has passed, the TVS diode returns to its normal state.

How to Use the SM712-02HTG

The SM712-02HTG is a bidirectional TVS diode, meaning that it can protect against transient overvoltage events from either polarity. To use the SM712-02HTG, simply connect it in parallel with the components that you want to protect. The SM712-02HTG is available in a SOT-23-3 package, making it easy to mount on printed circuit boards.

Conclusion

The SM712-02HTG is a versatile and reliable TVS diode that can be used to protect a wide range of electronic devices from transient overvoltage events. It is ideal for use in applications where high levels of protection are required, such as consumer electronics, industrial applications, and automotive systems.
