The DPAK (TO-252) surface-mount package with exposed tab allows the designer to manage junction temperature through PCB copper area or a heatsink. The 30 ns reverse recovery time places this diode in the fast-recovery class, not ultrafast. At 5 A forward current and 200 V blocking, the stored charge is low enough to keep turn-off losses manageable in a 50–100 kHz power stage. The 990 mV forward drop at 5 A is typical for a 200 V fast-recovery device; expect higher Vf at elevated junction temperature. The 50 µA reverse leakage at 200 V is a room-temperature maximum — leakage doubles roughly every 10°C above 25°C, so budget headroom in high-ambient designs. Buyers should verify date code and traceability requirements with their quality team before purchasing a surplus lot. The DPAK (TO-252) package has two leads plus a tab that is electrically common with the cathode. A heatsink or forced air may be needed if the combined dissipation exceeds the package's thermal impedance to ambient.","metaTitle":"STPR1020CB Fast Recovery Diode, 200V 5A Common Cathode, DPAK","metaDescription":"STPR1020CB fast recovery diode, 200V 5A per diode, 30ns trr, common cathode in DPAK.

A functionally equivalent fast-recovery diode with similar ratings (200 V, 5 A, common cathode, DPAK, trr ≤ 30 ns) would need to be selected and qualified by the design engineer.

The DPAK package's exposed tab can dissipate that with adequate PCB copper area, but a heatsink or forced airflow is recommended if the ambient temperature exceeds 85°C or if both diodes conduct simultaneously."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPR1020CB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPR1020CB when reusing this data.
