For this to happen, the gate pin of the TRIAC should receive a voltage greater than the threshold gate voltage and should also get a current that is greater than gate trigger current.

The whole process is outlined in Figure 6. By putting a resistor or a small capacitor or both in parallel between these two terminals, the capacitive current generated during the transient flows out of the device without activating it.

Snubber circuits are also used to prevent premature triggering, caused for example by voltage spikes in the mains supply. As in the case of a triggering in quadrant III, this lowers the potential of the n-layer and turns on the PNP transistor formed by the n-layer and the two p-layers next to it.

Other than controlling through switch the BT can also be controlled through a microcontroller or a microprocessor. This is because it is the only quadrant where gate current is injected directly into the base of one of the main device transistors.

However, the structure is different from SCRs. The lower p-layer works as the collector of this PNP transistor and has its voltage heightened: When switching on, the device starts to conduct current before the conduction finishes to spread across the entire junction.

This way the Load can not only be switched but also the output coltage can be controlled by using PWM signals for fast switching. Latching current is the minimum current that keeps the device internal structure latched in the absence of gate current.

Because each SCR will have an entire half-cycle of reverse polarity voltage applied to it, turn-off of the Traic is assured, no matter what the character of the load. Because in the TRIAC there are parasitic resistances, a high reverse current in the p-n triaf inside it can provoke a voltage drop between the gate region and the MT1 region which may make the TRIAC stay turned on.

This, in turn, causes the p, n and p layers over MT2 to behave like a PNP transistor, which turns on because its n-type base becomes forward-biased with respect to its emitter MT2.

In these situations it is normal to connect the bt1136 terminal to the positive rail of the microcontroller’s power supply, together with A1 of the triac, with A2 connected to the live. The mechanism is illustrated in Figure 3. In most applications, the gate current comes from MT2, so quadrants 1 and 3 are the only operating modes both gate and MT2 positive or negative against Tria. Its formal name is bidirectional triode thyristor or bilateral triode thyristor.

Add to Wish List. The reason is that during the commutation, the power dissipation is not uniformly distributed across the device. This in turn lowers the potential of the n-region, acting as the base of a pnp transistor which switches on turning the transistor on without directly lowering the base potential is called remote gate control. Therefore, the red arrow labeled with a “3” in Figure 6 shows the final conduction path of the current. English Choose a language for shopping.
