16TTS12FP

Thyristors - SCR, usually denote silicon-controlled rectifier (SCR) or silicon-controlled switch (SCS), are a type of semi-conductor component or device commonly employed in switching and regulating electric current. A 16TTS12FP SCR is an important variant of these devices, and one that is used in a variety of varying applications. This article will look into these 16TTS12FP SCR applications and its working principle.

As a direct current device, 16TTS12FP SCR utilizes four layer semiconductor structure, comprising of one p-type and one n-type in the form of PNPN structure. It allows to control high power in proportion to its size. Due to its exceptional characteristics, the SCR device is used in a variety of electronic applications, such as motor control, heater control, switching regulator circuits and LED lighting.SCR devices, such as the 16TTS12FP, are widely used in the automotive industry and its accessories, as current regulators in certain electrical circuits and as starting and control units in air conditioners and also in power converters. Additionally, they are widely employed in switch-mode power supplies as switches, providing high power and voltage solutions that are designed to achieve fast response times and high efficiency.SCRs are also mainly used in non-isolated power supplies and direct current (DC) magnetic brake control in high speed applications and in the energy management system. Its ability to switch the current to AC loads without the use of additional circuit is an added advantage for the AC drives applications.

This 16TTS12FP SCR is mainly a four-layer PNPN diode structure with four junction terminals, a cathode (K) and three further elements labelled main terminal (MT), anode (A) and gate (G). The main terminal acts as a common point for both anode and cathode but in opposite directions. The three layers of the PNPN diode in its structure can be seen as two diodes cross-connected to form a switch type device.The working principle of 16TTS12FP SCR is based on two opposite modes: forward blocking state and reverse conducting state. In forward blocking state, the anode current will not surpass a certain value during the period the applied voltage on the anode and cathode is positive, whereas in reverse conducting state the anode current will remain in constant until the anode voltage drops below zero while the gate terminal remains open. When a small positive voltage is applied to the SCR\'s gate terminal, the SCR will be conditionally turned on and remain in a conductive state until the anode current drops below a certain value, despite the gate voltage, due to the reverse recovery current of the PNPN. When the current reaches a certain threshold, the SCR turns off, hence switching it from OFF to ON state. Thus, this is the main working principle of the 16TTS12FP SCR.

In conclusion, 16TTS12FP SCR have a range of applications and have proven to be very useful in controlling and regulating electrical current, offering automated processes to control voltage and current and is used in a wide range of applications. The SCR works by allowing the current to flow when a certain voltage is applied to its gate terminal and blocking it when the voltage is reversed. The SCR device is incredibly versatile and provides a unique and effective solution for a variety of electronic applications.
