SCR Bridge Leg 1200 Volt 60 Amp Module ST STTN6050H-12M1Y for Heating Controllers and Power Supplies
Product Description
The STTN6050H-12M1Y is a 1200 V, 60 A full controlled SCR bridge leg integrated into an ACEPACK SMIT module. It is capable of controlling AC current up to 85 ARMS when connected to an AC line network. This device enables the design of single or three-phase AC DC rectifier bridges, phase recombination branches for totem pole PFCs up to 75 A(AVE) output current, AC phasing arms of line inverters, and back-to-back SCR based AC switches for heating controllers or UPS bypass relays. Its top cooling pad, positioned opposite the printed circuit board, facilitates automatic assembly of the PCB-module-heat sink stack, resulting in a low-profile and compact converter for on-board chargers, charging stations, motor drives, UPS, and AC-DC power supplies. Leveraging ST's high-temperature automotive ASD technology, it offers enhanced noise immunity of 1000 V/s at a 150 C junction temperature (Tj) and over-voltage robustness up to 1400 V (VDSM).
