SCE25C80 Description

SCE25C80 is a high-performance silicon controlled rectifier (SCR) device, an important member of the semiconductor switching element family. Silicon controlled rectifier, also known as thyristor, is a four-layer three-terminal semiconductor device with the characteristics of high efficiency, high reliability and long life.

Main Technical Parameters

  • Package type: TO-263
  • Off-state repetitive peak voltage/Reverse repetitive peak voltage (VDRM/VRRM): 800V
  • Maximum on-state current (IT(RMS)): 25A
  • Trigger current (IGT): ≤40mA
  • Dv/dt strong anti-interference ability: ≥200V/μs

Working Principle

When the trigger conditions are met, its PNPN structure will conduct to achieve the control of AC load. When the external trigger signal is applied to the gate, the thyristor enters the conduction state from the cut-off state, thereby driving the AC load. Since it is a bidirectional conduction device, it can conduct in both the positive and negative half cycles, which is suitable for AC control applications.

Typical Application

  • Lighting dimmers (such as incandescent lamps, halogen lamps)
  • Small household appliance control (such as rice cookers, electric heaters)
  • Motor speed regulation (fans, blenders)
  • Smart switches, timer switches
  • Low-power AC load switching in industrial control systems

Summary

SCE25C80 is a thyristor device with stable performance, compact package and strong on-state capability. It is particularly suitable for AC circuit control solutions that require high integration and large current carrying capacity. Its TO-263 package not only improves the heat dissipation efficiency, but also conforms to the manufacturing trend of miniaturization and automation of modern electronic equipment.
