BTA12 Manufacturer

STMicroelectronics, headquartered in Plan-les-Ouates, Switzerland, near Geneva, is a multinational electronics and semiconductors firm. The company was created in 1987 by the merger of two government-owned semiconductor companies: "Thomson Semiconductors" in France and "SGS Microelettronica" in Italy. It is known as "ST" and is the most profitable semiconductor chip producer in Europe. While the corporate headquarters and EMEA regional offices of STMicroelectronics are in Geneva, the holding company, STMicroelectronics N.V., is based in the Netherlands.

Frequently Asked Questions

1.Can the BTA12600B and BTA12800B be replaced?
When the voltage does not exceed 600V, they can be replaced with each other. It is necessary to pay attention to the replacement of the triode. Instead of using all the parameters of the triode, only some of the parameters are used. Therefore, the first replacement principle is to look at the function. For example, the triode used for high-frequency small-signal amplification mainly depends on the frequency of use of the triode. Second, look at the magnification. If it is used for low-frequency and high-power amplification, it mainly depends on the power, Uce (withstand voltage), Ice (maximum current) of the transistor, and secondly, the frequency of the transistor. For example, audio amplifier circuits have no requirements for frequency; power amplifiers and power supply circuits must pay attention to parameters such as Pcm and Vcb0; high frequency/intermediate frequency amplifiers and oscillation circuits must pay attention to the number of frequencies.
2.Can BTA12-600B and BTA12-600C be used in common?
The main data of BTA12-600B and BTA12-600C are the same, but some indicators are different. The maximum trigger current of BTA12-600B is 50MA; BTA12-600C is 25MA; The dv/dt voltage rise rate tolerance is also different, B-400 volts/microsecond; C-200 volts/microsecond. If the voltage change rate is not large in your application, or if it is zero-crossing conduction, the two can be used in common. If you use the occasion where the instantaneous voltage rise rate is very high, consider increasing the resistance and capacitance absorption, which can also be used universally.
3.Can the triac BTA12-600B be turned off?
Not only triacs, general unidirectional SCRs and standard SCRs can only control its turn-on, and turn-off is when the current flowing through it is small to a certain value (maintenance current ), and this will turn off the control pole naturally when there is no additional signal, so the thyristor is a bit more troublesome in use. When you want to turn it off when it is used in DC, you have to give it It can only be completed after it creates a condition that is smaller than its maintenance current.
4. What type of devices does the BTA12 triac family consist of?
Glass passivated PNPN devices with good performance.
5. What type of current capacity does the BTA12 triac require?
High surge current capacity.
6. What are examples of a BTA12 triac?
Phase control and static switching on inductive or resistive loads.
