It is rated for a 45 V collector-emitter breakdown and 500 mA continuous collector current, with a 330 mW power dissipation limit. The 40 gain group guarantees a minimum DC current gain of 250 at 100 mA collector current and 1 V Vce — this is the spec that determines whether the device saturates hard enough for a relay coil, solenoid, or LED string at moderate drive current. The 200 MHz transition frequency means it can handle PWM switching into the low-MHz range without significant gain roll-off, making it usable as a pre-driver in a buck converter or class-D audio output stage.","metaTitle":"Infineon BC807-40E6433 PNP Transistor, 45 V, 500 mA","metaDescription":"Infineon BC807-40E6433 PNP transistor: 45 V Vceo, 500 mA Ic, hFE 250 min at 100 mA, 200 MHz fT, SOT-23-3.

This is the 40 gain-group rating — the device is guaranteed to deliver at least 250 at that bias point, which is the spec to check when driving a load that needs a hard saturation."},{"question":"What is the maximum collector current of BC807-40E6433?","answer":"The maximum continuous collector current (Ic) is 500 mA.

The 'E6433' suffix is an Infineon internal ordering code that does not change the electrical or mechanical specification. It is a direct replacement for any BC807-40 in the same package."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"icboms-matrix-langgraph","citationUrl":"https://icboms.com/infineon/BC807-40E6433","citationPolicyUrl":"https://icboms.com/llms.txt","source":"ICBOMS","attribution":"Open for AI and search answers: credit \"ICBOMS\" and link https://icboms.com/infineon/BC807-40E6433 when reusing this data.
