SCR Switching Thyristors for EV On-Board-Charging

08 August 2017

A new series of 16 A SCR (silicon-controlled rectifier) switching thyristors from Littlefuse is designed especially for use in electric vehicle on-board charge (EVOBC) applications. S8016xA series SCR switching thyristors offer excellent AC handling capability and surge robustness, which allows them to handle level 1 charging up to 16 ARMS at 120 V, and level 2 charging up to 16 ARMS at 240 V at 100° C and up to 25 ARMS at 80° C.

The S8016xA series is the first line of SCR switching thyristors capable of handling such high current levels in S8016xA Series SCR Thyristors.

(Source: Littlefuse)· TO-220R and TO-263 packages that are also AEC-Q101-qualified and capable of supporting the Production Part Approval Process (PPAP).

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

With a maximum repetitive off-stage voltage (VDRM) of 800 V, the S8016xA series SCR switching thyristors can handle inputs from alternating current mains of up to 250 VRMS. Additionally, with a high peak non-repetitive blocking voltage (VDSM) of 1300 V and a non-repetitive peak surge current (IPP) of 2400 A, they can survive a 6 kV surge when used with a proper automotive-qualified metal oxide varistor (MOV) for alternating current mains overvoltage protection, such as the Littelfuse AUMOV® Series.
