It comes in a surface-mount SOT-223 package (PG-SOT223-4-21) and operates across a -55 to 150 °C junction temperature range. This is a small-signal high-voltage switch — think auxiliary supplies, bias rails, relay pre-drivers, and off-line start-up circuits where the load is under 120 mA and the bus voltage can hit 600 V. The SIPMOS series is Infineon's established high-voltage MOSFET family; the part is widely stocked through both franchised and independent channels.","metaTitle":"Infineon BSP125L6433 N-Channel MOSFET, 600 V, 120 mA","metaDescription":"Infineon BSP125L6433 SIPMOS N-channel power MOSFET, 600 V drain-source, 45 Ohm Rds(on) at 10 V, 120 mA continuous drain.
