The forward drop is specified at 880 mV maximum when each diode is carrying 15 A, so conduction losses are predictable in a 30 A total-output design. ## 120 V blocking and 15 A per leg — sizing the rectifier stage The 120 V reverse voltage rating sets the maximum DC bus voltage this Schottky can block. In a typical 48 V or 60 V output power supply, you get healthy derating margin. The 15 A per-diode average rating means the pair can handle a combined 30 A in a center-tapped or full-wave configuration, but the thermal limit in the I2PAK will be the real constraint — the junction is rated for 150°C maximum, so you need to size the heatsink for the sum of the forward losses at your operating current. At 15 A per diode the 880 mV Vf produces about 13.2 W per die, which is a lot of heat to pull through a through-hole tab. ## Schottky switching — no stored charge to manage This is a Schottky diode, so reverse recovery is negligible — the <500 ns speed classification is really a formality; a Schottky's majority-carrier action means it turns off with almost no stored charge. The 200 µA reverse leakage at 120 V is typical for a 120 V Schottky at temperature; expect it to rise significantly at the 150°C junction limit, so derate the blocking voltage if the heatsink runs hot. ## Active status — no LTB pressure If you are qualifying this for a new design, you can expect standard lead times and no forced redesign horizon from obsolescence.","metaTitle":"STPS30L120CR Schottky Rectifier","metaDescription":"STPS30L120CR dual Schottky rectifier: 120V Vr, 15A per diode, 880mV Vf at 15A, I2PAK through-hole.

If ST were to issue an EOL notice in the future, a pin-compatible Schottky in the same I2PAK package with matching 120 V / 15 A ratings would be the natural substitute. For now, there is no replacement needed."},{"question":"What does the 880 mV forward drop at 15 A mean for my thermal design?","answer":"At 15 A per diode, each die dissipates about 13.2 W. With two diodes in the package, the total conduction loss can reach 26.4 W if both legs are conducting simultaneously. The I2PAK tab must be bolted to a heatsink sized for that dissipation, and the 150°C junction limit sets the maximum case temperature you can allow."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/stmicroelectronics/STPS30L120CR","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/stmicroelectronics/STPS30L120CR when reusing this data.
