The tab is the cathode connection for both diodes in the common-cathode pair, so the PCB pad must handle both the thermal and electrical connection. No lab bench needed for the swap — a hot-air station with a D2PAK nozzle and a preheat plate gets it done on site, but the tab solder joint needs a good thermal soak to avoid a cold joint. ## Obsolete — sourcing reality and the replacement question This part is listed as obsolete.

A pin-compatible replacement would need to match the D2PAK footprint, 200 V reverse voltage, 8 A per diode, common-cathode configuration, and 30 ns or faster reverse recovery time — a parametric search across fast-recovery diodes in D2PAK is the practical path to find a cross."},{"question":"What is the reverse recovery time of the STPR1620CG-TR?","answer":"The reverse recovery time (trr) is 30 ns, which qualifies it as a fast-recovery diode (≤500 ns, >200 mA Io). This 30 ns trr is the key spec for switching applications — it determines the turn-off loss in a hard-switched converter and sets the upper bound on switching frequency before efficiency drops off."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPR1620CG-TR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPR1620CG-TR when reusing this data.
