Frequently Asked Questions
What are the maximum voltage and current ratings of BC807-40W-7 for switching circuit design?
BC807-40W-7 is rated at 45 V collector-emitter breakdown voltage (VCEO) and 500 mA maximum collector current (IC), with a minimum DC current gain (hFE) of 170. These ratings make it suitable for switching loads up to 500 mA from logic-level base drives in 3.3 V and 5 V microcontroller systems.
How does the BC807-40W-7 differ from BC807-25W-7 in gain classification for amplifier designs?
BC807-40W-7 belongs to the higher gain group with minimum hFE of 170 (typically 250–450 at 100 mA), while BC807-25W-7 has a lower minimum hFE of 100. For small-signal amplifier designs requiring predictable gain with less variation, the -40 suffix version provides tighter high-gain selection, beneficial in audio pre-amp stages operating at collector currents between 2 mA and 100 mA.
Which load types can BC807-40W-7 switch effectively from a 3.3 V microcontroller GPIO pin?
With hFE of 170 and IC up to 500 mA, BC807-40W-7 can switch relay coils (typically 50–100 mA), LED arrays (up to 500 mA), and small DC motors from a 3.3 V GPIO with as little as 3 mA base current. The 45 V VCEO provides headroom for inductive load flyback spikes in relay and solenoid switching applications.
