For a typical 10 nC gate charge, the rise time is about 100 ns and fall time 50 ns — fast enough for switching frequencies in the tens of kHz without excessive cross-conduction losses. If your IGBT or MOSFET has a total gate charge above 100 nC, the driver will still switch it, but the transition times stretch and the dead-time margin narrows. ## Supply rail and logic thresholds The driver operates from a 10 V to 20 V bias supply. The 600 V high-side bootstrap rating means the floating high-side driver can reference a switching node that swings up to 600 V above the low-side ground, which covers the majority of three-phase motor-drive and UPS inverter rails. Sourcing is through independent distribution — stock is available on the spot market, and we quote each order against the BOM quantity. The 8-PDIP package is a through-hole form factor that suits rework and prototype builds as well as legacy production runs.","metaTitle":"IR2103 Half-Bridge Gate Driver, 600 V Bootstrap, 8-PDIP","metaDescription":"Infineon IR2103 half-bridge gate driver for IGBT/N-channel MOSFET. 600 V bootstrap, 210/360 mA peak output, -40 to 150 °C junction.","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":"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":"IR2103","Driven Configuration":"Half-Bridge","Operating Temperature":"-40°C ~ 150°C (TJ)","Rise / Fall Time (Typ)":"100ns, 50ns","Supplier Device Package":"8-PDIP","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":"$2.8100","priceTiers":null},"links":{"datasheetUrl":null,"sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR2103/alternatives.json"},"ai":{"faq":[{"question":"Is IR2103 obsolete?","answer":"Yes, the IR2103 is listed as Obsolete. It is no longer manufactured by Infineon. Sourcing is through independent distribution — we can supply it against an RFQ from available spot-market inventory."},{"question":"What is a replacement for IR2103?","answer":"No official replacement or successor is listed on the record for the IR2103. The IR2104 is a common cross-shop candidate — it shares the same half-bridge architecture and 600 V bootstrap rating but differs in input logic (the IR2104 uses shutdown logic rather than independent inverting/non-inverting inputs). Pin compatibility should be verified against the target PCB layout before substituting."},{"question":"What voltage does IR2103 work with?","answer":"The IR2103 operates from a 10 V to 20 V bias supply. The high-side bootstrap is rated for a maximum of 600 V."},{"question":"Can IR2103 be used for high-side gate drive?","answer":"Yes. The IR2103 is a half-bridge driver with a 600 V high-side bootstrap rating. The high-side output drives the gate of an N-channel MOSFET or IGBT referenced to the switching node, which is the standard topology for high-side gate drive in a half-bridge or full-bridge converter."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IR2103","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IR2103 when reusing this data.
