Description

The SCA40C80 SCR is highly capable of handling the shock loads caused by large currents and offers a high dV/dt rating, making it highly resistant to electromagnetic interference. It is particularly suitable for applications such as solid-state relays, motorcycles, power chargers, and power tools. It provides a rated insulation voltage of 2000 VRMS between all three terminals and an external heatsink. The TO-220A package complies with RoHS standards.

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

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.

Features and Advantages

1.TO-220A Package Advantages

  • Metal back plate design, easy to install heat sink
  • High mechanical strength, not easily damaged by installation or temperature changes

2.Performance Advantages
