The MXUPT17E3 is a miniaturized Transient Voltage Suppressor (TVS) – diode that helps protect electrical circuits, equipment and data line applications by providing highly reliable and cost-effective protection from electrical transients. Manufactured and marketed by Littelfuse, Inc., this robust and compact unit helps in protecting sensitive microprocessors, data lines, and other components from transient overvoltage due to ESD, EFT, surge, and inductive loads. The MXUPT17E3 TVS – diode helps reduce downtime and sub-assembly costs by providing an effective, easy to install, surge protection solution.

The MXUPT17E3 features a 2.5 A peak pulse power capability (tp = 8/20 μs). Its low-capacitance, small form factor design technology helps provide superior circuit board area savings, contributing to improved protection performance. With an ultra-fast 2.0 ns response time, the MXUPT17E3 TVS – diode is ideal for protecting both power and data line circuits from overvoltage transients. It provides for greater design flexibility due to the wide clamping voltage range from 1.0 – 17 V, and its low clamping voltage reduces power consumption in power-sensitive applications. The MXUPT17E3 is also RoHS compliant.

The MXUPT17E3 helps protect sensitive equipment and data lines from electrical transients and is suitable for a wide range of applications including power supplies and protection of equipment such as microprocessors, data lines, and other sensitive devices.

The working principle of this TVS – diode mechanism is simple: electrical transients cause an increase in voltage. This causes the diodes to become forward-biased and conduct current, thereby limiting the voltage to a safe level. For power line protection, two to four diodes are connected in parallel in a bridge configuration. For data line protection, the diodes are connected in a series configuration. The TVS – diode then conducts current in one direction until the overvoltage condition is over, and then reverts to its off state.

The MXUPT17E3 is designed to protect against overvoltage transients up to an 8/20 μs pulse and comes in an ultra-small (E3PAK package). Its hermetically sealed package provides the highest level of mechanical reliability. The MXUPT17E3 also utilizes an advanced silicon-based technology, which helps to cut costs due to its compact size and low profile. The combination of low capacitance, high surge capability, and fast response makes the MXUPT17E3 an ideal choice for transient protection in a wide range of consumer and industrial applications.

In conclusion, the MXUPT17E3 TVS – diode is a high-performance device providing superior surge current capability and fast response. Its easy to use, hermetically sealed package, and low profile design ensures reliable protection from transient events in a wide variety of consumer and industrial applications.
