Hello readers welcome to new post. We will discuss Introduction to BTA12 TRIAC. It is snubbers logic level normally used triacs. It is a medium power consumer TRIAC created by ST Microelectronics. It has high energy dissipation operation and less holding current creating fines option for different applications such as LED dimmers and motor control circuits.
Here we will cover all basics of BTA12 TRIAC and some other related paramerts. So let get started.
Introduction to BTA12 TRIAC
- The BTA12 is a medium power user TRIAC has less value of holding current so used for motor control and lED dimmers.
- It comes with a larger value of surge energy that makes it suitable for inductor loads applications.
- It is done since the thermal mass of die absorbs the energy released from the pulses before the temperature increment.
- It is used for on and off functions in different applications like static relays induction motor starting circuits and phase regulators.
- This module is also used for speed control of motor operations and is mostly preferred for inductor loads.
BTA12 TRIAC Features
- Different features of this triac are discussed here
- It is medium power user current triac
- Its packaging is RoHS compatible
- It is less thermal resistance insulated material
- It gives the larger value of surge current.
- It is six hundred volts power and twelve ampers current value have
- It has less thermal resistance bonding
- Comes with TO220 packaging
- Twenty watts power dissipation it has
BTA12 TRIAC Pinout
- The main pinout of this triac are discussed here
- A1 is used to the current movement in and out
- A2 current goes in and out from it
- G is used for control of current flow between A1 and A2
BTA12 TRIAC Applications
- Applications of this triac are used here.
- Used in LED dimmer circuits
- Part of induction motor speed control circuits
- Used for inductor loads
BTA12-600B Equivalent
- BTA16600B, BTA12800B, BTA16600B,
- BTA24600B, BTA24800B, BTA16800B, BTA20600B, BTA20800B
Working of BTA12
- The BTA12 is a medium-power employed triac that has low holding current and is good for motor controllers and LED dimmer circuits.
- The BTA12 comes with high surge energy features that mean it can handle inductive loads without the use of a snubber.
Can BTA12600B be replaced with BTA12800B?
- If voltage does not cross 600 volts, they can be replaced with each other. It is needed to give features for replacing tried. Then, using all features of the triode, some factors are used.
- So the first replacement feature is to check the triode used for high-frequency small-signal amplification based on the frequency of the triode.
- The second is to check magnification; it is used for low-frequency and high-power circuits. It is also based on power, maximum current of the transistor, and frequency of the transistor.
- The audio amplifier circuit comes with no demand for frequency, power amplifiers, and power supply circuits needed for factors like Pcm and Vcb0;
Is it possible to use BTA12-600B and BTA12-600C commonly?
- The main features of A12-600B and BTA12-600C are similar with some differences. The maximum trigger current of BTA12 is 50 mA, and BTA12 600C is 25 mA.
- The dv/dt voltage increase rate is also not the same. If the voltage change rate is not large for the application, or if it is zero crossing conduction, the two are used for common.
- For applications where the instantaneous voltage rise rate is high, follow increasing resistance and capacitance absorption that are used universally.
Can the triac BTA12-600B be turned off?
- Not only does a triac unidirectional SCR and standard SCR only control turn-on and turn-off when current is passing through small for a certain value.
- It will turn off the control pole needed when it is used for DC.
What type of devices does the BTA12 triac have?
- Glass passivated PNPN devices used
What current capacity does the BTA12 triac require?
- High surge current capacity.
What are common examples of a BTA12 triac?
- Phase control and static switching
What is BTB12-600B?
- BTB12-600BWRG is a 3-pin non-insulated TRIAC. It is good for general-purpose AC switching circuits. It comes with moderate current, low thermal resistance, clip bonding, and high commutation features.
