TD350E

TD350E Description

The TD350E from STMicroelectronics is a high-performance single-channel IGBT gate driver designed for high-side switching applications. Packaged in a 14-pin SO (Small Outline) tube, this surface-mount IC operates within a 12V to 26V supply range, making it suitable for robust power management systems. With peak output currents of 1.5A (source) and 2.3A (sink), it ensures efficient switching of IGBTs and MOSFETs, while its fast rise/fall times (130ns typical, 75ns max) minimize switching losses. The device is ROHS3 compliant, REACH unaffected, and rated for MSL 3 (168 hours), ensuring reliability in industrial environments.
