Description

With high ability to withstand the shock loading of large current, SCD12C80 of silicon controlled rectifiers,provides high dV/dt rate with strong resistance toelectromagnetic interference. It is especially recommended for use on solid state relay, motorcycle,power charger,T-tools etc. Package TO-252 is RoHS compliant.

Main Technical Parameters

  • Package type: TO-252
  • Off-state repetitive peak voltage/Reverse repetitive peak voltage (VDRM/VRRM): 800V
  • Maximum on-state current (IT(RMS)): 12A
  • Trigger current (IGT): ≤15mA
  • Dv/dt strong anti-interference ability: ≥200V/μs

Features and Advantages

  • High blocking voltage capability: 800V repetitive peak turn-off voltage, suitable for high voltage applications.
  • Strong surge current withstand capability: 140A surge current, suitable for motor starting and power surge protection.
  • Excellent thermal cycling performance: Fully plastic package, providing good thermal conductivity and electrical isolation, suitable for high-frequency thermal cycle industrial environment.
  • Low trigger current and voltage: Low gate trigger current and voltage, easy to integrate with low-power control circuits (such as microcontrollers).

Working Principle

Inside the SCD12C80 is a four-layer semiconductor structure (PNPN) with three pins:

  • A (Anode)
  • K (Cathode)
  • G (Gate)

It is essentially a controlled switch that will only conduct when certain conditions are met.

SCD12C80 adopts a unidirectional conduction structure. Its working principle is based on the on-off control of the PNPN structure. The device is turned on by an external gate trigger current and is used to control high current loads.

Typical Application

  • Crowbar protection
  • Inrush protection
  • Motor control
  • Voltage regulation
