STMicroelectronics – First 1200 V automotive-grade SCR ensures ultra-reliable power conversion

Automotive-grade, 1200 V, 50 A SCR: TN5050H-12WY

AC/DC converter applications

The TN5050H-12WY is optimized for a wide range of AC/DC converter applications, including electric vehicles and other battery chargers, renewable energy inverters, solid-state relays and UPS. It offers superior surge-current handling (580 A), power dissipation capability (R_th=0.3 °C/W, T_j max=150 °C), and overvoltage robustness up to 1300 V, while uniquely enhancing reliability, quality, and supply of components with the AEC-Q101 certification. This new SCR enables designers to achieve the same level of efficiency as traditional diode bridges, but with lower cost and a smaller PCB footprint.

This 1200 V, 50 A automotive-grade thyristor makes AC/DC converters safe by limiting the inrush current and providing insulation against AC line overvoltages

Available in a TO-247, high power package, the TN5050H-12WY automotivegrade SCR is suitable for automotive / stationary battery
chargers, renewable energy generators, uninterruptible power supplies, solid state relays, welding equipment and motor drive applications.
The TN5050H-12WY offers superior performance in surge current handling (ITSM = 200 A at 10 ms), thermal cooling capabilities (Rth(j-c)
= 0.3 °C/W) and high surge voltage withstanding capability (VDSM/VRSM = 1300 V).
