Its key differentiator is the 600 V maximum bootstrap voltage on the high side, which sets the upper DC-link voltage limit for motor drives, UPS inverters, and switch-mode power supplies. The two independent channels — one high-side, one low-side — accept both inverting and non-inverting input logic, giving the controller flexibility on polarity. ## Gate drive current and switching speed Peak output current is rated 210 mA source and 360 mA sink. This asymmetry favours fast turn-off of the power switch — the higher sink current pulls the gate down quickly, reducing cross-conduction dead-time margin. The supply range of 10 V to 20 V covers standard gate drive rails for both MOSFETs (10-15 V) and IGBTs (15-20 V). Infineon no longer manufactures this exact ordering code in production volumes. No official successor is listed on the Infineon cross-reference for this exact PDIP variant, so any replacement must be validated against the board footprint and the 8-DIP socket. The 8-PDIP through-hole package (0.300-inch body width) is a legacy footprint; it suits socketed prototyping, low-volume production, or rework scenarios where a surface-mount package would complicate manual replacement. The Tube shipping medium is the factory packaging for this DIP variant.","metaTitle":"IR2103PBF Half-Bridge Gate Driver, 600V Bootstrap, Obsolete","metaDescription":"IR2103PBF half-bridge gate driver from Infineon. 600V bootstrap, 210/360 mA peak output, 8-PDIP.

The pinout differs — the IR2104PBF uses pin 3 for SD instead of the IR2103PBF's IN pin on that position. Footprint is the same 8-DIP package, so a board designed for one can accept the other with a firmware or logic change."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/IR2103PBF","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/IR2103PBF when reusing this data.
