## **Description** 

The TN3050H-12WY is an automotive grade SCR Thyristor designed for applications such as automotive on-board chargers, solid state AC relays and stationary battery chargers. 

This SCR Thyristor, rated for a 30 A RMS power switching, offers superior performance in peak voltage robustness up to 1400 V and surge current handling up to 300 A sine wave pulse. Its key features allow the design of functions such as a 42 A RMS AC switch (dual back-to-back SCRs) and a 38 A average AC-DC controlled rectifier bridge for inrush current limitation. 

Available in through-hole TO-247 package, this power package allows a thermal operation up to 30 A RMS with a higher case temperature of 126 °C.
