The 8 A per diode average current is derated by junction temperature — the maximum junction temperature is 175°C, so the actual continuous current in a 85°C ambient enclosure may be lower depending on PCB copper area and airflow. The common-cathode pair in a single DPAK saves board space compared to two discrete diodes, but the shared cathode tab means both diodes must see the same DC potential on their cathodes — typical for center-tap full-wave rectifiers.","metaTitle":"STPS16170CB Schottky diode, 170 V, 8 A, DPAK, obsolete","metaDescription":"STPS16170CB is a 170 V, 8 A dual Schottky rectifier in DPAK.

It is no longer manufactured by STMicroelectronics. For existing production, the part can be sourced through independent distribution on a quoted-to-order basis."},{"question":"What is the replacement for STPS16170CB?","answer":"No official pin-compatible replacement from STMicroelectronics is recorded. A parametric search for a 170 V, 8 A common-cathode Schottky in DPAK is advised to find a drop-in alternative from ST or other manufacturers."},{"question":"What is STPS16170CB's listed speed?","answer":"The STPS16170CB is a Schottky diode with fast recovery characteristics: ≤ 500 ns at > 200 mA (Io). This is typical for Schottky technology, which switches faster than a standard PN-junction rectifier."},{"question":"Can I use STPS16170CB for 12V system?","answer":"Yes, the 170 V reverse voltage rating is far above a 12 V system's requirements, so the part will function. However, for a 12 V rail, a lower-voltage Schottky (e.g., 40 V or 60 V) would offer lower forward voltage drop and better efficiency at the same current."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS16170CB","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS16170CB when reusing this data.
