Product Specification
| Repetitive Peak On-state Current (Itrm) | 1A | Description | DO-15 DIACs, SIDACs RoHS |
| Mfr. Part # | K1050G | Package | DO-15 |
| Model Number | K1050G |
The SIDAC is a silicon bilateral voltage triggered switch designed for high-voltage applications. It activates when the applied voltage exceeds its breakover voltage, transitioning through a negative resistance region to a low on-state voltage. Conduction is maintained until the current drops below the device's minimum holding current. Featuring glass-passivated junctions, these SIDACs offer ruggedness and reliability for demanding environments. They are suitable for AC circuits and provide triggering voltages ranging from 79V to 330V.

Careful selection of the correct device for the application’s operating parameters and environment will go a long way toward extending the operating life of the Thyristor. Overheating and surge currents are the main killers of SIDACs. Correct mounting, soldering, and forming of the leads also help protect against component damage.
