Typical applications include load switching, driver stages for relays or LEDs, and signal amplification in consumer, industrial, and automotive auxiliary electronics where space on the board is tight. The BC 807-40W carries an obsolete lifecycle status. Infineon no longer manufactures this specific order code in volume, so the only available channel is the surplus and aftermarket market. The 45 V Vce breakdown and 500 mA collector current give this transistor enough headroom for 12 V and 24 V rail switching with a reasonable safety margin. The 250 mW power limit in the SOT-323 package means the junction temperature climbs quickly above 100 mA continuous — check the derating curve if the device is driving a load near 200 mW at elevated ambient. The 200 MHz transition frequency is adequate for audio-frequency amplifiers and low-speed switching up to a few megahertz; it is not a high-speed RF part. The 100 nA ICBO cutoff current is typical for a small-signal PNP and will not cause leakage issues in most low-power designs, but it matters in high-impedance bias networks where nanoamp-level leakage can shift operating points.","metaTitle":"BC 807-40W E6433 PNP Transistor, 45 V, 500 mA, SOT-323","metaDescription":"Infineon BC 807-40W E6433 PNP transistor, 45 V Vce, 500 mA Ic, 250 mW, 200 MHz ft, SOT-323.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"Obsolete","categoryPath":["Discrete Semiconductors"],"specifications":{"Mfr":"Infineon Technologies","Series":"-","Package":"Tape & Reel (TR)","Power - Max":"250 mW","Mounting Type":"Surface Mount","Package / Case":"SC-70, SOT-323","Product Status":"Obsolete","Transistor Type":"PNP","lifecycle_stage":"eol_hot","Base Product Number":"BC 807","Operating Temperature":"150°C(TJ)","Frequency - Transition":"200MHz","Supplier Device Package":"PG-SOT323","Vce Saturation (Max) @ Ib, Ic":"700mV @ 50mA, 500mA","Current - Collector (Ic) (Max)":"500 mA","Current - Collector Cutoff (Max)":"100nA (ICBO)","DC Current Gain (hFE) (Min) @ Ic, Vce":"250 @ 100mA, 1V","Voltage - Collector Emitter Breakdown (Max)":"45 V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":null,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dac6601666718a637184a14be301b183.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/BC%20807-40W%20E6433/alternatives.json"},"ai":{"faq":[{"question":"Is BC 807-40W E6433 obsolete?","answer":"Yes, the BC 807-40W E6433 is listed as obsolete.

Within the BC 807 family, a current-production variant with the same SOT-323 footprint and -40 gain group (e.g., BC 807-40W H6327) may be a direct drop-in, but verify the exact specifications against your BOM.
