The two-channel synchronous output drives the high-side and low-side switches with a typical 80 ns rise and 40 ns fall time, providing clean transition edges for the 125 mA source and 250 mA sink peak current capability. ## 600 V bootstrap — what the rail rating means The high-side bootstrap is rated to 600 V maximum. The 10 V to 20 V supply range on the low-side bias rail means the undervoltage lockout thresholds are fixed for standard MOSFET gate thresholds. No official successor part is recorded in the lifecycle data, meaning any substitute requires a board-level review of pinout, oscillator timing, and UVLO thresholds. Sourcing is through independent distribution against an RFQ.","metaTitle":"IR2151S Half-Bridge Gate Driver, 600V Bootstrap, 8-SOIC","metaDescription":"IR2151S half-bridge gate driver for IGBT/N-Ch MOSFET. 600V bootstrap, 125/250 mA peak output, 10-20V supply.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Gate Type":"IGBT, N-Channel MOSFET","Input Type":"RC Input Circuit","Channel Type":"Synchronous","Mounting Type":"Surface Mount","Package / Case":"8-SOIC (0.154\\\", 3.90mm Width)","Product Status":"Obsolete","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 20V","Number of Drivers":"2","Base Product Number":"IR2151","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"80ns, 40ns","Supplier Device Package":"8-SOIC","Logic Voltage - VIL, VIH":"-","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"125mA, 250mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR2151S/alternatives.json"},"ai":{"faq":[{"question":"Where can I buy IR2151S online?","answer":"The IR2151S is obsolete and sourced through independent distribution.

The 80 ns rise and 40 ns fall times are adequate for small- to medium-die IGBTs in half-bridge configurations up to a few tens of kHz switching frequency, limited by the RC oscillator timing."},{"question":"What is the difference between IR2151S and IR2153?","answer":"The IR2151S and IR2153 share the same half-bridge driver core and 8-SOIC package, but they are not pin-compatible without a layout change. The IR2153 uses a fixed deadtime and a different oscillator pin arrangement. Do not substitute without comparing the datasheet pinout and RC timing circuit."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IR2151S","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IR2151S when reusing this data.
