Thyristors - SCRs (silicon-controlled rectifiers) are a form of power semiconductor device which can turn on large currents, while they require relatively small current or voltage to be initiated. They are used as an efficient power control device in various applications such as power supplies, industrial motor drives, heaters and lighting. The BT169H-LML is a type of SCR, which is used for controlling and managing AC power. This device is capable of controlling current to a maximum of 6000V and 400A. It also comes with a built-in over-temperature protection, and with a low trigger current consumption.

The BT169H-LML is made up of two main parts, the anode and the cathode. The anode is typically an N or P-type semiconducting material, while the cathode is formed by a thin layer of metals. When an initial charge is supplied, the electrons start to flow between the anode and the cathode, causing a voltage to be generated across them. This voltage controls the amount of current that flows. When the current reaches the maximum level, the device turns off and no further current can flow.

The BT169H-LML has two gate terminals, one for controlling the on-off state, and the other for controlling the current. The on-off gate terminal can be used to manually switch the device on or off. The current gate terminal allows for more accurate control of the current by adjusting the voltage applied to it. This can be used to achieve more precise and efficient power control.

In applications where the BT169H-LML is used, it is typically connected in series with an inductive load, such as an AC motor, transformer, or rectifier. During operation, the gate voltage is applied, and the current starts to flow, powering the load. The current through the device then continues to flow in the same direction, until the gate voltage is removed. This causes the device to switch off, and the current flow stops.

The BT169H-LML also has the capability to switch large currents in both directions, providing increased protection and safety. This allows it to be used in applications where the current must be quickly and efficiently controlled in either direction. This can be used, for example, in circuit protection, where large currents must be switched off rapidly to protect the circuit.

The BT169H-LML is a highly reliable and efficient SCR, which is capable of efficiently controlling large currents in both directions, in a variety of applications. This makes it an ideal choice for controlling AC power in industrial motor drives, heaters, power supplies, and lighting.
