STMicroelectronics introduces Automotive-grade SCR Thyristors which provide control over inrush current for battery chargers and safely handle capacitor discharges.

ST's 1200 V, automotive-grade SCR Thyristors, TN4050HP-12WY (40 A) and TN6050HP-12WY (60 A), offer optimized power loss dissipation and are AEC-Q101 qualified for EV on-board chargers from 3.7 to 22 kW. The products feature 600 A surge current capability and 200 A/μs turn-on reliability as they also fit battery management systems. Rated at a junction temperature of 150°C, the TN6050HP-12WY SCR offers 1 kV/μs immunity, and a 1400 V surge, ideal for handling capacitor discharges.
