It integrates a 600 V bootstrap supply for the high-side driver, making it a compact choice for motor drives, switch-mode power supplies, and ballast circuits where a single RC input sets the oscillator frequency. ## 125 mA source, 250 mA sink — gate drive muscle With a peak output current of 125 mA source and 250 mA sink, the IR2151 can charge and discharge the gate capacitance of medium-power IGBTs and MOSFETs fast enough for switching frequencies typical in half-bridge converters. The 80 ns rise and 40 ns fall times (typical) keep switching losses in check when the gate charge stays within the driver's current budget. ## 10 V to 20 V supply range The supply voltage range of 10 V to 20 V covers standard gate drive levels for both IGBTs (typically 15 V) and logic-level MOSFETs (10 V). The 600 V bootstrap rating on the high side means the driver can sit on a half-bridge rail up to 600 V DC, which covers 230 VAC and 400 VAC inverter stages with margin. ## Through-hole 8-PDIP — field-swappable Housed in an 8-pin PDIP (0.300\" wide), the IR2151 is a through-hole part that can be swapped in the field with basic tools — no hot-air station needed. ## Obsolete — sourced on the secondary market","metaTitle":"IR2151 Half-Bridge Driver, 600V Bootstrap, 125mA/250mA","metaDescription":"IR2151 half-bridge gate driver for IGBT/N-channel MOSFET, 600V bootstrap, 125mA/250mA peak output, 8-PDIP.","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":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","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-PDIP","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/IR2151/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for IR2151?","answer":"The IR2153 is a commonly discussed alternative in the same family, but it is not a pin-compatible drop-in — verify the pinout and oscillator timing before substituting."},{"question":"What is the IR2151 used for?","answer":"The IR2151 is a half-bridge gate driver used in motor drives, switch-mode power supplies, and electronic ballasts.
