It's a general-purpose power diode built for the high-voltage side of PFC stages, snubber circuits, and output rectification in switched-mode supplies where the reverse recovery characteristic determines the switching loss. ## 105 ns trr at 15 A — what that buys you on the switching side Reverse recovery time is 105 ns at 15 A forward current and 1200 V blocking voltage. That's the number that sets the cross-conduction window in a hard-switched topology — a slower recovery diode would overlap with the MOSFET turn-on and burn the efficiency curve. At 15 A continuous, the 2.1 V forward drop at rated current is the conduction loss floor; the thermal design has to sink that plus the switching loss from the recovery tail. ## Through-hole DOP3I — the insulated tab matters on a high-voltage rail That saves assembly time and improves thermal transfer. ## Active production, ROHS3, sourced on request It's ROHS3 compliant, so no exemption paperwork needed for the BOM.","metaTitle":"STTH1512PI Fast Recovery Diode, 1200V 15A DOP3I-2","metaDescription":"STTH1512PI 1200V 15A fast recovery diode, 105ns trr, through-hole DOP3I-2 insulated package.
