How do I know if which leg is the emitter or the collector? (Transistor . . . Off the cuff - for jellybean transistors I almost invariably use BC337 (NPN) and BC327 (PNP) - both CBE A transistor selector book woul;d be the easy way to check distributions as they have pinout tables which they assign a letter code to and then show the relevant code for each device
Finding the Base-Emitter Voltage in an NPN Transistor Start by solving for the base current, treating the BE junction as a diode in series with Rb The collector current doesn't really effect the base current Then use beta to get the collector current and calculate Vout If your calculated Vout is less than Vce (sat), then you must be in saturation mode, so you know Vout is Vce (sat), and Ic = (Vcc-Vce (sat)) Rc
How exactly does CPU set C BE lines on a PCI bus? This questions starts from a bit of misunderstanding: in actuality, the CPU doesn't directly talk on the PCI bus, a PCI bus bridge does that, on behalf of the CPU or peripheral to which it is connected
Radio transmitter using a crystal oscilliator I am on a mission to control my RC car using a Arduino The simplest way I thought of doing this is to add Arduino outputs into the transmitter Long story short I wanted to learn more about how th
BJT high frequency analysis - Electrical Engineering Stack Exchange From what I remember, the Cbe depends on the emitter current Higher current causes lower reac (1 gm); at 1mA, its 26 ohms at 2mA its 13 ohms 2mA is 4 volts 2Kohm (ignoring the emitter bypass cap) Thus your circuit has an incremental emitter-base small-signal resistance of about 13 ohms If the 2N2222 has 160MHz Ftau, the emitter-base needs 1nanosecond time-constant, or 1,000 picoSeconds
Same transistor type, swapped emitter and collectors? Normal? But there are two different pinouts for the P2N2222A (a CBE pinout) and the PN2222 (EBC pinout ) So at least given my BC547 ignorance it seems at least possible in concept that other devices may have varying pinouts as I already know one example where it happens
CBE Schematic and Wiring - Electrical Engineering Stack Exchange I'm in the process of installing a circuit breaker between a power supply and an HMI device, but have some uncertainty when it comes to illuminating the rocker switch The part number is TA35-C2F3F
