STMicroelectronics STSID140-12, Gate Driver, 40 mA 8-Pin 3.47V, DFN

The STMicroelectronics integrated insulated gate driver is designed for reliable control of AC switches such as SCRs and Triacs in industrial applications. It provides functional insulation up to 1.25 kVRMS, ensuring safe operation when driving thyristors across a wide range of conditions. With its Compact design and low standby current, it is well suited for energy‑efficient and robust motor and power control systems.

• Output current capability of 40 mA for driving thyristors
• Operates from a single 3.3 V supply for direct MCU interfacing
• Maximum junction temperature supported up to 125 °C
• Input to output isolation tested at 2121 VPK for safety compliance
• High creepage distance of 3.92 mm meeting IEC 60335‑1 requirements for 250 VRMS applications
