Application of K1400S1URP

DIAC (double-ended bidirectional trigger diode) is often used in the startup circuit of SCR because of its trigger characteristics, to help SCR transition from the blocking state to the on-state, to achieve accurate control of alternating current. DIAC is also used in lighting dimming systems, motor speed control, and solid-state relays as a key trigger element. SIDAC is used in power management and temperature control system because it is used as a switch directly. For example, when the power supply is started, SIDAC (silicon bidirectional trigger diode) can sense the rise in voltage and automatically turn on the circuit, avoiding the delay and unreliability of traditional mechanical switches. At the same time, SIDAC is also used in overvoltage protection circuit, when the voltage is abnormally increased, SIDAC will quickly turn on, bypass the excess energy, and protect the subsequent circuit from damage.

K1400S1URP Classification

Thyristors - DIACs, SIDACs

DIAC (Double-ended bidirectional trigger diode) is a non-polar semiconductor device that has the same characteristics at forward and reverse voltages. DIAC is mainly used to trigger SCR or other phase controlled devices, when the applied voltage reaches its threshold voltage, DIAC will be switched on and make the current increase rapidly, thus triggering the phase controlled device. SIDAC (Silicon bidirectional trigger Diode) is similar to DIAC, but with added temperature compensation and higher trigger voltage stability. SIDAC is also used for triggering thyristor isopexes, but is designed to maintain consistent triggering performance at different temperatures.

FAQ about Thyristors - DIACs, SIDACs

  • 1. How do DIACs differ from SIDACs?

    DIACs exhibit symmetrical voltage thresholds in both directions, while SIDACs often have higher breakover voltages and are suitable for applications requiring higher current capacities.

  • 2. What is the breakover voltage of a DIAC or SIDAC?

    The breakover voltage is the voltage at which the device becomes conductive. It varies depending on the specific device, typically ranging from 30V to 250V for SIDACs.

  • 3. How does temperature affect DIACs and SIDACs?

    Their operation is temperature-dependent, with most devices rated for operation between -40°C and 125°C. Higher temperatures can affect their triggering voltage.
