TVS - Mixed Technology

Transient Voltage Suppressors (TVS) are specialized diodes used in electrical systems to protect against abnormal voltage transients, such as those caused by lightning strikes, power cross, electrostatic discharge (ESD) and induced electrical fields. Traditionally, TVSs have been made of either two diodes connected in series, or a single diode with a zener diode combination. However, with the advent of advanced technology, a new type of TVS was developed using a more complex construction of semi-conductors and capacitors. This type of TVS is referred to as mixed technology TVS, and the most commonly used example is the P1701UCLRP.

The P1701UCLRP, or commonly referred to as the Unidirectional TVS, is a unidirectional type of TVS that is designed to provide excellent transient protection for applications operating in a range of 6V to 48V. It is constructed using a combination of MOSFETs, diodes and capacitors, and is designed to offer a much higher level of protection than the traditional two-diode or single-diode zener diode combinations. The P1701UCLRP is typically used in applications where protection from transient voltage higher than 48V needs to be provided. The P1701UCLRP is often used in motor control circuits, medical equipment and laser systems.

The working principle of the P1701UCLRP can be broken down into two main parts. The first part consists of the MOSFETs and diodes, which are configured in a series of three stages. The first stage is designed to detect any voltage transients that may occur. When a transient is detected, the MOSFETs in the first stage will then act to switch off the affected circuit. The second stage will then detect the current flowing in the affected circuit, and the third stage will act to control the amount of current flow by switching the MOSFETs on or off.

The second part of the P1701UCLRP’s working principle involves the capacitor. This capacitor is designed to store the excess energy caused by the aforementioned transient. This excess energy is then slowly released over time, which keeps the current flow at a constant level. This ensures the protection of the affected circuit, as well as keeping the operating voltage of the system within the desired range.

In summary, the P1701UCLRP is a mixed technology television suppression device that offers superior protection from transient voltage higher than 48V. It is designed to detect any transients that may occur, and then regulate the flow of current by controlling the MOSFETs and the capacitor. The P1701UCLRP is most commonly used in motor control circuits, medical equipment and laser systems.
