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. 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.
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. That 150°C junction ceiling is not a case temperature — derate the output current if the board runs hot inside an enclosed drive.
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.
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.
