It integrates a bootstrap diode rated for 600 V on the high side, allowing the high-side driver to float up to that rail voltage. The two output channels are independent, with separate inverting and non-inverting inputs for flexible dead-time control. ## 210 mA source, 360 mA sink — gate-drive muscle for mid-power stages Peak output current is rated 210 mA source and 360 mA sink. That sink-heavy ratio is intentional — it pulls the gate down faster than it charges it, which helps prevent shoot-through during the dead-time interval. The supply range is 10 V to 20 V, covering standard 12 V and 15 V gate-drive rails. ## Obsolete — plan for a replacement or source from surplus For new designs, look at the IR2104 or other pin-compatible half-bridge drivers in the same family — but confirm the input logic and dead-time matching against your BOM. ## 8-SOIC footprint — standard surface-mount layout The 8-pin SOIC is a common footprint for gate drivers, so a board layout designed for a similar part (e.g. IR2104, IR2110 in SOIC-8) should accept this device with no PCB changes.","metaTitle":"IR2103S Half-Bridge Gate Driver, 600 V Bootstrap, 8-SOIC","metaDescription":"Infineon IR2103S half-bridge gate driver for IGBT/N-channel MOSFET. 600 V bootstrap, 210/360 mA peak output, 8-SOIC.","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":"Inverting, Non-Inverting","Channel Type":"Independent","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":"IR2103","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"100ns, 50ns","Supplier Device Package":"8-SOIC","Logic Voltage - VIL, VIH":"0.8V, 3V","High Side Voltage - Max (Bootstrap)":"600 V","Current - Peak Output (Source, Sink)":"210mA, 360mA"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$2.0700","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR2103S/alternatives.json"},"ai":{"faq":[{"question":"What is the replacement for the IR2103S?","answer":"No official successor is listed.
