It is rated for a collector-emitter breakdown voltage of 45 V and a continuous collector current of 500 mA, with a power dissipation of 250 mW. The -40 gain group guarantees a minimum DC current gain of 250 at 100 mA collector current and 1 V Vce, making it suitable for medium-current switching and linear amplification in low-power circuits. 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. ## Obsolete — sourcing through independent distribution 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,"stockQuantity":0,"priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/dac6601666718a637184a14be301b183.pdf","sourceUrl":null},"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.
