The common-cathode configuration means the two anodes are separate pins (pins 1 and 3), the cathode is the centre pin and the metal tab. In a continuous 15 A per-diode load the total dissipation reaches 31.5 W; the TO-220 junction-to-case thermal resistance (not listed here) typically runs 1–2 °C/W, so a heatsink is mandatory above a few amps per die. The base product number is STTH3002; the CT suffix denotes the TO-220 package variant.","metaTitle":"STTH3002CT 200V 15A dual common-cathode fast-recovery diode","metaDescription":"STTH3002CT dual common-cathode fast-recovery diode, 200 V, 15 A per diode, 22 ns trr, TO-220-3.

This is the time from zero-crossing of the forward current to the reverse current decaying to 10 % of its peak value, measured under standard test conditions. It is fast enough for 100 kHz+ hard-switched converters."},{"question":"Can I use STTH3002CT as a replacement for STTH2002CT?","answer":"The STTH2002CT is a lower-current variant (20 A vs 30 A total, 10 A per diode vs 15 A per diode) in the same TO-220 package. The STTH3002CT has a higher current rating and the same 200 V reverse voltage and 22 ns trr. It can replace the STTH2002CT in the same footprint provided the higher current capability does not exceed the downstream circuit's surge rating or heatsink capacity."},{"question":"Is STTH3002CT RoHS compliant?","answer":"Yes, the STTH3002CT is ROHS3 compliant, meaning it meets the EU RoHS directive without any of the exempted substances above the threshold limits."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH3002CT","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH3002CT when reusing this data.
