Introduction

Transient Voltage Suppressor (TVS) diodes are a well-known type of semiconductor designed to protect semiconductor devices and other components against voltage overshoots. A TVS diode is basically an attempt to suppress voltage transients from damaging the device. It is a two-terminal device which short circuits or clamps any voltage surges above a specific threshold voltage and helps manufacturers to protect their devices from short transients.

MXUPT33E3 Application Field and Working Principle

The MXUPT33E3 is a 3.3V TVS diode designed to protect against voltage transients. It is widely used in consumer, automotive, industrial, medical and aviation applications. This TVS diode is ideal for automotive and consumer applications which require protection against ESD, EFT, EMI, lightening and other transients.The MXUPT33E3 is a fast response diode that is capable of handling voltage transients up to 33V peak spike with a maximum reverse leak current of 2.5A. It has low capacitance of 2.2pF and low capacitance variation. The MXUPT33E3 is designed with a diode clamp configuration and is reverse biased when voltage remains below its maximum rated clamping voltage. When the reverse voltage applied exceeds the rated clamping voltage, the diode will switch to the forward-bias in a few nanoseconds and the breakdown voltage will be clamped at the rating. The diode can still conduct current in forward-bias, so it will limit the pulse amplitude and provide extra protection for the devices. Once the pulse passes, the diode will switch back to reverse bias and return to its original state.

Conclusion

In conclusion, the MXUPT33E3 is a 3.3V transient voltage suppressor (TVS) diode used to protect sensitive circuit components from voltage transients. It is ideal for automotive and consumer applications requiring protection from ESD, EFT, EMI, and lightening. It has a fast response time and can handle up to 33V peak spikes with low capacitance and capacitance variation. It operates on a diode clamp configuration and its breakdown voltage is clamped at its rated clamping voltage and can quickly return to its original state once the pulse has passed.
