Switching thyristor series is robust for EV on-board charging

The S8016xA SCR switching thyristor' AC handling capability and surge robustness allow them to handle Level 1 charging up to 16ARMS at 120V, Level 2 charging up to 16ARMS at 240V at 100°C and up to 25ARMS at 80°C. They are claimed to be the first line of SCR switching thyristors capable of handling such high current levels in TO-220R and TO-263 packages that are also AEC-Q101-qualified and capable of supporting the Production Part Approval Process (PPAP) making them suitable for protecting a Level 1 AC on-board charger.

Typical applications are input rectification of AC line inputs for electric vehicle on-board and off-board chargers.

The compact TO-220R and TO-263 packages help minimise circuitry size. The maximum repetitive off-stage voltage (VDRM) (800V) can handle inputs from AC mains of up to 250V RMS. An RMS on-state current (IT(RMS)) up to 25A makes the thyristors suitable for use with Level 1 and Level 2 AC charging applications. The peak non-repetitive blocking voltage (VDSM) of 1300V and a non-repetitive peak surge current (IPP) of 2400A, enables the thyristors to survive a 6kV surge when used with an automotive-qualified metal oxide varistor (MOV) for AC mains over-voltage protection; the company cites its own AUMOV series.

The S8016xA series is available in TO-220R and TO 263 (D2-Pak) packaging. Samples are available on request from the manufacturer's authorised distributors worldwide.
