Product details

30 ns reverse recovery time — the switching edge that matters

The STTH1R02A is a 200 V, 1.5 A standard fast recovery diode from STMicroelectronics, built for applications where reverse recovery time drives switching loss. Its 30 ns trr keeps the turn-off energy low in continuous-current topologies like power-factor correction boost stages and flyback snubbers.

Forward drop and leakage — thermal budget inputs

Forward voltage is specified at 1 V max at 1.5 A, which sets the conduction loss floor for the 1.5 A average rectified current rating.

SMA footprint and reflow compatibility

The DO-214AC (SMA) package is a standard surface-mount outline compatible with reflow soldering profiles. Tape-and-reel and cut-tape options are available, supporting both prototype and production pick-and-place runs.
