600 V, 15 A, 50 ns — the power-stage fit
The STTH15RQ06G2Y-TR is a 600 V, 15 A fast-recovery diode from STMicroelectronics. The 50 ns trr keeps turn-off energy low for hard-switched boost PFC or DC-DC converters. The D2PAK HV package cathode tab sits on the backside copper pad — board copper area under the tab sets RthJA.
AEC-Q101 and 175°C junction — the automotive gate
AEC-Q101 qualification is the gate for any automotive BOM line — this part carries it, so the PPAP submission is straightforward. The ECOPACK2 suffix means the part is lead-free and RoHS-compliant per ST's own green-packaging directive, so no exemption paperwork needed for the EU RoHS annex.
The lifecycle status is Active — no last-time-buy notice, no EOL window. That means the BOM line can be committed for the current production run without a shortage scramble.
