What the IR2301SPBF is and where it fits
The Infineon IR2301SPBF is a high-side or low-side gate driver in an 8-SOIC package, designed to drive IGBTs and N-Channel MOSFETs in half-bridge or independent-channel configurations. It handles bootstrap supply up to 600 V on the high side, making it a natural fit for motor drives, uninterruptible power supplies, and PFC stages where the DC bus sits at several hundred volts. The two channels are independent and non-inverting, so you can use them as a complementary half-bridge pair or as two separate low-side drivers — the datasheet shows both arrangements.
Package and mounting
Peak output current is 200 mA source, 350 mA sink. Typical rise time is 130 ns, fall time 50 ns. Supply range is 5 V to 20 V. Logic input thresholds are 0.8 V (VIL) and 2.9 V (VIH). High-side bootstrap rating is 600 V. Junction temperature range is -40°C to 150°C, which puts it in the industrial/motor-drive class. That 150°C junction ceiling is not a case temperature — derate the output current if the board runs hot inside an enclosed drive.
Package and mounting
The 8-SOIC (0.154", 3.90 mm width) is a standard footprint — no surprises under the hot-air station. The part ships in Tube form, which means it arrives in a stiff plastic carrier with the leads protected. If you are feeding a pick-and-place, you will need to transfer to tape or order a tape-and-reel variant — the IR2301SPBF is Tube only.
Lifecycle and sourcing
The IR2301SPBF is listed as Active with ROHS3 compliance. For dual-sourcing resilience, the closest functional peer in the same family is the IR21064STRPBF — same gate type (IGBT, N-Channel MOSFET), same non-inverting independent channels, same 150°C junction rating, and same 8-SOIC footprint. The IR21064 has a slightly slower rise time (150 ns vs 130 ns) and a 10 V minimum supply, so check the supply rail before swapping.
