Reverse leakage is 15 µA at the 170 V blocking voltage. The junction temperature maxes out at 175°C. This part is typically used in high-frequency output rectification for switch-mode power supplies, freewheeling diodes in motor drives, and OR-ing diodes in redundant power systems where the Schottky's low forward drop and fast recovery (under 500 ns) reduce switching losses. STMicroelectronics lists the STPS16170CR as obsolete. If you are in the design phase, plan for a last-time-buy or a validated alternative; do not lock a new board into an obsolete diode. ## Package and mounting — through-hole I2PAK The STPS16170CR comes in a TO-262-3 long-lead package (I2PAK, TO-262AA). It is a through-hole mount, which simplifies manual assembly and rework compared to surface-mount power packages. The I2PAK tab is the common cathode — plan the heatsink attachment accordingly. The tube shipping medium is fine for low-volume production runs.","metaTitle":"STPS16170CR Schottky Diode, 170V 8A Common Cathode, TO-262","metaDescription":"STPS16170CR dual Schottky rectifier: 170V Vr, 8A per diode, 920mV Vf at 8A, TO-262 I2PAK.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"STMicroelectronics","Speed":"Fast Recovery =< 500ns, > 200mA (Io)","Series":"-","Package":"Tube","Technology":"Schottky","Mounting Type":"Through Hole","Package / Case":"TO-262-3 Long Leads, I²Pak, TO-262AA","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Base Product Number":"STPS16170","Diode Configuration":"1 Pair Common Cathode","Supplier Device Package":"I2PAK","Current - Reverse Leakage @ Vr":"15 µA @ 170 V","Voltage - DC Reverse (Vr) (Max)":"170 V","Operating Temperature - Junction":"175°C (Max)","Voltage - Forward (Vf) (Max) @ If":"920 mV @ 8 A","Current - Average Rectified (Io) (per Diode)":"8A"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$1.5700","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/ccbe4daf3ae15ae46a9df3670aaea456.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/STPS16170CR/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for STPS16170CR?","answer":"No official replacement part number is listed by STMicroelectronics. For a pin-compatible alternative, check the STPS16170CT — it shares the same 170 V / 8 A per diode ratings and common-cathode configuration, but comes in a TO-220AB package rather than the I2PAK.
