STMICROELECTRONICS STTH212U Ultrafast Diode 1.2kV 2A DO-214AA

The STMICROELECTRONICS STTH212U is a high voltage ultrafast diode engineered for efficiency and reliability in demanding electronic applications. It features a low forward voltage drop and a high surge current capability, which contributes to reduced power losses, particularly in high-frequency switching operations. The diode utilises ST's advanced ultrafast high voltage planar technology, enabling soft switching characteristics that help minimise electromagnetic interference (EMI) disturbances.

This component is designed for high reliability, with an RMS voltage rating of 850V and a junction-to-lead thermal resistance of 25°C/W. Its robust construction ensures stable performance in power management circuits where durability and consistent operation are critical. The compact DO-214AA (SMB) case style makes it suitable for space-constrained PCB designs.
