50 A rectifier for high temperatures: Rutronik introduces AEC-Q101-qualified SCR series SV6050xAx from Littelfuse

09/14/2023 Product News

Littelfuse has launched the SVxx50xAx series of AEC-Q101-qualified semiconductor-controlled rectifiers designed for automotive applications, specifically for electric and hybrid vehicles. The thyristor offers a peak off-state voltage of 600 V and a gate trigger-rated current range of 6 mA to a maximum of 15 mA. The SV6050xAx high-temperature SCR series is ideal for unidirectional switching applications such as phase angle controls, motor speed controls, solid-state relays and inrush current controls. A notch on one pin discreetly indicates that the housing – through-hole or SMD – is not isolated. Both variants are available at www.rutronik24.com.

For electric and hybrid vehicles, there are some legally fixed regulations to ensure, among other things, reliable occupant protection in the event of a vehicle accident. These include that the high-voltage (HV) mains installed in these vehicles must be discharged below a voltage of less than 60 V within a few seconds. Their original DC voltage of up to 500 V or more and the connected high-voltage battery, pose a considerable danger in the event of a short circuit. It is therefore necessary to disconnect the HV mains and isolate the high-voltage battery from the high-voltage mains.


  • Good thermal performance (Rth(JC) 0.7 °C / W).
  • Allows high-temperature operation at 50 A
  • Prevents false triggering due to fast electrical transients across terminals in the AC mains
  • High inrush current capability
  • Overvoltage resistance up to 550 A at 60 Hz half-wave
  • Maximum junction temperature: TJ = 150 °C
  • dv / dt noise immunity up to 1000 V / µs
  • di / dt capability up to 100 A / µs

Further features:

  • Clip-die-attach assembly
  • Halogen-free and RoHS compliant
  • AEC-Q101 qualified

Application examples:

  • Rectifiers and voltage regulators
  • AC solid-state switch
  • Inrush current limiting circuit
  • Overvoltage protection with clamping circuit (crowbar)
  • Phase regulators
