Working Principle:
- Forward Blocking State: The thyristor does not conduct in the forward direction until triggered.
- Gate Triggering: Application of a sufficient voltage or current to the gate turns the thyristor on.
- Conduction Phase: Once triggered, the thyristor conducts until the current drops below a certain level.
- Latching: The thyristor remains conducting until the current through it is interrupted or drops below a holding current level.
Alternative Models:
- BT136: Higher current rating alternative to the BT134 series.
- BT169G: Lower power SCR suitable for control applications.
- MAC97A6: Compact and efficient alternative for light dimming circuits.
The BT134-600,127 serves as a reliable Silicon Controlled Rectifier for medium-power switching applications, providing controlled power management for various loads.
