The maximum forward voltage is 1.95 V at 15 A, which at 25°C is typical for a 600 V-class fast recovery die. Reverse leakage is 10 µA at 600 V, low enough to avoid thermal runaway in a hot boost stage. For a 1.5 kW PFC running from a 400 V DC rail, the 600 V margin leaves room for switching transients without avalanche stress. ## Common-cathode pair in TO-247 — layout and thermal The 1 Pair Common Cathode configuration means the cathodes are internally tied to the center tab of the TO-247-3 package, with the two anodes on pins 1 and 3. This saves a PCB footprint versus two discrete TO-220 diodes for center-tapped secondary rectification or interleaved boost stages. The through-hole TO-247-3 package handles the thermal dissipation through the tab — a heatsink with a flat mounting surface and thermal compound is assumed for continuous 15 A per leg. Mounting torque per the datasheet recommendation avoids die stress. ST lists the STTH30AC06CWL as an active product.","metaTitle":"STTH30AC06CWL fast recovery diode","metaDescription":"STMicroelectronics STTH30AC06CWL dual common-cathode fast recovery diode, 600 V, 15 A per leg, 55 ns trr, TO-247-3.

However, the STTH30AC06CWL's 55 ns trr at 600 V is faster than many 200 V-class ultrafast parts, so substitution requires checking the voltage rating and recovery time against the circuit's worst-case blocking voltage and switching frequency."},{"question":"What is the STTH30AC06CWL's listed speed?","answer":"The STTH30AC06CWL is classified as a Fast Recovery diode with trr = 55 ns at 15 A and 600 V. This puts it in the ultrafast recovery class, suitable for hard-switched PFC and output rectification up to about 100 kHz switching frequency."},{"question":"Is STTH30AC06CWL compatible with MUR3020?","answer":"The MUR3020 is a 200 V, 30 A common-cathode ultrafast diode in TO-247. The STTH30AC06CWL has a 600 V blocking voltage versus 200 V, so the ST part can replace the MUR3020 in a 200 V circuit with voltage margin, but the reverse is not true — a MUR3020 would fail in a 600 V application. Both share the same package and pinout, so they are mechanically interchangeable in a 200 V design, but the 55 ns trr of the ST part is comparable to the MUR3020's typical recovery time."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STTH30AC06CWL","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STTH30AC06CWL when reusing this data.
