Diodes - Rectifiers - Arrays
BYT261PIV-400 is a high-throughput DIAC (diode alternative circuit), which is a two-terminal switch used in AC and DC switching applications. It is usually used in circuits to provide a DC voltage drop, as well as an electrical insulation layer between two electrical components. It is also used as a frequency-expanding, by-shift double diode element. It is ideal for AC/DC rectification, power management and voltage regulation applications.
Application Field
The BYT261PIV-400 is used primarily for its low forward voltage drop, low forward conduction resistance and high peak current capabilities. BYT261PIV-400 DIACs are most commonly found in:
- Power supply regulators, such as buck-boost or flyback configurations.
- Motor speed controllers, in order to prevent motor stalling during acceleration.
- Electric power control systems.
- Circuit protection (thermal cut-outs, miniature breakers and overcurrent protection circuits).
Working Principle
The working principle of the BYT261PIV-400 DIAC is based on a two-terminal electronic switch consisting of two junctions, connected in series. When a voltage is applied to the anode, electrons from the cathode flow towards the anode until the junction\'s barrier potential is reached. Once this occurs, electrons from the cathode proliferate in the anode, and the diode is forward biased, allowing current to flow in the circuit.
In the reverse direction, a diode must be biased beyond its reverse breakdown voltage before it will turn on. In this state, the diode is in its "blocking" mode, where it presents an open-circuit to the reverse bias voltage. In normal operation, the BYT261PIV-400 DIAC is OFF, but when an external voltage applied to the cathode-anode junction is sufficiently high, current begins to flow freely through the diode. The voltage required to activate the diac is known as a holding voltage.
Once the diac is triggered, current will flow until the surge current limit is reached, at which point the diac will switch off and the current will cease. This on-off triggering mechanism can be used to create a variety of waveforms, such as sine waves and square waves, which can be used for a variety of control and regulation applications.
