It integrates a bootstrap diode for the high-side floating supply, rated to 600 V. The 8-PDIP through-hole package suits prototype builds and low-volume production. ## 210 mA source, 360 mA sink — gate drive muscle Peak output current is 210 mA sourcing and 360 mA sinking. The asymmetric sink rating pulls the gate low faster than it charges, reducing cross-conduction in hard-switched half-bridges. ## NRND — last-time-buy planning required Infineon lists the IR2104PBF as Not Recommended for New Design (NRND). New designs should migrate to the current-production IR2104S or IR2104STRPBF (SOIC-8) or evaluate the pin-compatible IR2104-2 family if through-hole is mandatory. For existing BOM lines, the NRND status means a last-time-buy window is open — secure the forecasted lifetime volume or qualify an alternate before the final order cutoff. Operating supply spans 10 V to 20 V, matching the gate-drive voltage range for standard MOSFETs and IGBTs. The non-inverting input type means the HO and LO outputs follow the IN pin state directly; no deadtime generation is integrated, so the PWM source must insert deadtime in firmware or external logic. ## 150 °C junction — motor-drive and industrial ambient The 150 °C Tj ceiling allows the die to run hot when the ambient is elevated and self-heating from gate-drive losses adds to the temperature. The 8-PDIP package has a junction-to-ambient thermal resistance around 100 °C/W, so forced airflow or a heatsink is unnecessary at typical gate-drive duty cycles.","metaTitle":"IR2104PBF Half-Bridge Gate Driver, 600 V, 210/360 mA, NRND","metaDescription":"Infineon IR2104PBF half-bridge gate driver for IGBT/N-channel MOSFET. 600 V bootstrap, 210 mA source / 360 mA sink, 8-PDIP.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Power Management (PMIC / Gate Driver)"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tube","Gate Type":"IGBT, N-Channel MOSFET","Input Type":"Non-Inverting","Channel Type":"Synchronous","Mounting Type":"Through Hole","Package / Case":"8-DIP (0.300\\\", 7.62mm)","Product Status":"Not For New Designs","lifecycle_stage":"eol_hot","Voltage - Supply":"10V ~ 20V","Number of Drivers":"2","Base Product Number":"IR2104","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":"$3.1200","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/55cdba86a12abe951302711c1ca721e2.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/IR2104PBF/alternatives.json"},"ai":{"faq":[{"question":"What is the IR2104PBF gate type and what does it drive?","answer":"The IR2104PBF drives N-channel MOSFETs and IGBTs in a half-bridge configuration.
