Its 27 ns reverse recovery time (trr) places it squarely in the fast-switching class — think power-factor-correction boost stages, output rectification in 100–200 kHz SMPS, and snubber clamping where recovery charge drives the loss. The 1.1 V forward drop at 10 A per diode is typical for a 200 V planar epitaxial structure; at 15 A average per diode the junction is rated to 175 °C maximum, so the TO-262 tab needs a proper heatsink when both diodes conduct continuously. ## Dual common-cathode: board layout and thermal planning The two diodes share a common cathode (pin 2 and tab), which simplifies the PCB layout for a centre-tapped secondary or a two-phase interleaved PFC — the anodes connect independently, the cathode is the tab. The 15 A average per diode is the per-junction rating; if both diodes carry current, the total average is 30 A, and the package thermal resistance (junction-to-case, not stated here) must be derated accordingly. The 10 µA reverse leakage at 200 V is a room-temperature figure; expect it to rise with junction temperature, so the blocking voltage margin matters in high-ambient designs. ST lists the STTH2002CR as Active.","metaTitle":"STTH2002CR 200 V 15 A Ultrafast Diode, 27 ns trr, TO-262","metaDescription":"STMicroelectronics STTH2002CR ultrafast recovery rectifier: 200 V, 15 A per diode, 27 ns trr, 1.1 Vf at 10 A, TO-262 I2PAK.
