Its 45 ns reverse recovery time (trr) at 8 A forward current and 600 V blocking voltage places it squarely in the class of ultrafast diodes used for continuous-conduction-mode (CCM) power-factor-correction boost stages and high-frequency flyback output rectification. ## D²PAK tab — the thermal path is the copper pour For 8 A continuous conduction, the tab needs a minimum of 600 mm² of 2-oz copper on the top layer, stitched through to the inner planes with at least nine vias. The forward voltage drop at 8 A is 3.2 V max, so at full load the part dissipates about 26 W — that tab-to-ambient thermal resistance is the design constraint, not the silicon. The 30 µA reverse leakage at 600 V is typical for this voltage class and won't drive standby losses in an automotive 12 V system. ## AEC-Q101 — what the automotive stamp buys you This is the same die as the standard STTH8R06, but screened and with full lot traceability. For a production BOM going into an ECU or a DC-DC converter module, the AEC-Q101 grade is what the PPAP package requires — the non-automotive variant won't pass the customer's quality gate.","metaTitle":"STTH8R06GY-TR Automotive Fast Recovery Diode","metaDescription":"STMicroelectronics STTH8R06GY-TR is an AEC-Q101 qualified fast recovery diode rated 8A average, 600V reverse voltage, 45ns trr.
