TISP4240M3LM

Thyristors (also known as silicon-controlled rectifiers or semiconductor-controlled rectifiers) are a class of semiconductor devices with four alternating layers of semiconductor material. They have three terminals and are controlled by a gate, making them ideal for use in non-linear digital circuits, power control and digital circuit control. The TISP4240M3LM thyristor is a high power, low-inductance, positive temperature coefficient triac that is available in TO-220 packages.

The TISP4240M3LM is a passivated, surface mountable, three-terminal thyristor with three active junctions: a main junction which is formed between its anode and gate, a cathode junction, and a circuit junction between the anode and cathode. It is primarily intended for line-commutated applications, such as temperature control circuits, soft-start circuits, and some load switching circuits. Specifically, it is suited for the automatic proportional control of applications such as lighting and heating circuits. It is designed to operate from 0 to 600 VDC, while its sense voltage can go up to 240 VDC.

The TISP4240M3LM is designed so that it can be triggered cleanly and quickly, thanks to its special gate design. With its built-in trigger protection, its performance is well-suited for a variety of applications. When switching, it does not cause harmful EMI around it, meaning it is suitable for use in many industrial systems. It also offers reverse current blocking, and its power dissipation is very low, allowing it to be used in power-sensitive applications.

The TISP4240M3LM thyristor also has some impressive ratings. Its current range is from 0.2 A to 4 A, its power rating is 8 W, its thermal resistance range is from 25 Ω to 40 Ω, and its thermal impedance range is from 37°C/W to 65°C/W. It has a very high blocking voltage of up to 800 VDC, and its breakdown voltage is 600 VDC.

The TISP4240M3LM thyristor is used in a variety of applications, such as air-conditioning systems, computer fan controllers, temperature controllers, motor speed controllers, and inductive load circuits. It can even be used in dryers and washing machines, as well as in lighting and electric heating systems. Thanks to its low inductance, high-performance ratings, and price, it is a popular choice among manufacturers.

The working principle behind the TISP4240M3LM thyristor is fairly simple and straightforward. When an external voltage is applied to its gate terminal, the voltage across the main junction increases and allows current to flow through the thyristor. This current then flows through the device and creates a voltage across its cathode junction, making the thyristor turn “on”. Once the thyristor is turned “on”, it remains so until its voltage across its main junction is removed (which happens when its external voltage is taken away).

The TISP4240M3LM thyristor is a great choice for many applications due to its high performance ratings and cost-efficiency. Whether it’s used in air-conditioning systems, motor speed controllers, or temperature controllers, this thyristor can get the job done efficiently and reliably. Thanks to its low inductance, high blocking voltage, and high current rating, this device is definitely a go-to choice for many electronics manufacturers.
