Description
The TYN840 is a robust 800V, 40A Silicon Controlled Rectifier designed for high-voltage switching and power control applications. Its TO-220A package provides efficient thermal management and easy integration into heat sinks or power assemblies, making it suitable for compact or thermally challenging designs.
Main Technical Parameters
- Package type: TO-220A
- Off-state repetitive peak voltage/Reverse repetitive peak voltage (VDRM/VRRM): 800V
- Maximum on-state current (IT(RMS)): 40A
- Trigger current (IGT): ≤35mA
- Dv/dt strong anti-interference ability: ≥200V/μs
TYN840 Datasheet
Working Principle
SCR is a four-layer, three-terminal semiconductor device with three terminals: anode (A), cathode (K) and gate (G). When a positive voltage is applied to the anode relative to the cathode and a positive trigger current is applied to the gate, the SCR turns on. Once turned on, even if the gate trigger signal disappears, the SCR will remain in the on state until the main current drops below the holding current.
