The ROHS3 compliance covers the EU RoHS exemption regime; no additional compliance paperwork is needed for European automotive builds. ## D²PAK footprint — what the pick-and-place needs to know The D²PAK (TO-263) package has a large exposed tab on the bottom that must be soldered to the PCB copper island for both electrical connection and thermal dissipation — the reflow profile should follow the solder paste manufacturer's recommendation for the pad size, typically 4.9 mm x 10.4 mm for the tab.","metaTitle":"STPS40170CGY-TR Schottky Diode, 170V 20A, AEC-Q101, D2PAK","metaDescription":"STMicroelectronics STPS40170CGY-TR automotive Schottky diode array. 170V Vr, 20A per diode, 920mV Vf, AEC-Q101 qualified.

STPS40170CGY-TR is the Tape & Reel (TR) variant for automated pick-and-place assembly, while the base STPS40170CGY without the -TR suffix typically ships in tube or bulk form. The electrical specifications and package are identical."},{"question":"What is the reverse recovery time of STPS40170CGY-TR?","answer":"The STPS40170CGY-TR is a Schottky diode, which by its majority-carrier nature has negligible reverse recovery charge — the listed speed is Fast Recovery =< 500 ns, > 200 mA, but in practice a Schottky's recovery is much faster than a PN diode, typically in the tens of nanoseconds range. The 500 ns figure is a classification boundary, not the actual recovery time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS40170CGY-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS40170CGY-TR when reusing this data.
