Product details

30 ns reverse recovery time — what it buys the switching stage

The STTH3R02Q is an STMicroelectronics ultrafast rectifier rated for 200 V DC reverse voltage and 3 A average rectified current, housed in a DO-204AC (DO-15) axial-lead through-hole package. The 1 V forward voltage drop at 3 A is typical for a fast diode of this current class, and the 3 µA reverse leakage at 200 V is low enough to avoid significant off-state losses in most PFC and flyback designs.

STMicroelectronics lists the STTH3R02Q as obsolete. Date-code provenance matters here: the last-time-buy window has closed, so stock on the open market carries varying date codes, and we screen for authenticity before quoting.
