The transistor is a semiconductor device that can amplify signals and switch power. Most used types are bipolar (BJT, for Bipolar Junction Transistor), UJT (Unijunction transistor) and MOSFET (FET, for Field Effect Transistor)

This classification for hFE binning appears to be a number that is 10% of the mean bin value. If not specified on order then you get “open bin” which means any bin. Fortunately inexpensive DMM’s ha …

When transistor is off , then both LEDs will be on, BUT at reduced current since 2 R's are in series. To toggle LED's a complementary BJT switch is preferred, or a CMOS inverter using 5V max. …

simulate this circuit – Schematic created using CircuitLab Note that since transistor inverts output, you use (Vin-) for positive (+) feedback. LM393 open collector NPN has an equivalent ESR. …

1) \$Rce[\Omega] = Vce_{(sat)}/Ic\$ , always rated for \$Ic/Ib=10\$ (to 20 to 50 in special types) Thus \$Rb =10*Rc\$ is typical (not = Rc) for CMOS thus high and low often similar Z out for 1 or 0 …

As a Rule of thumb all Transistors are rated at Ic/Ib=10 even if the Vce(sat) is reasonably low at a ratio of 20 or special devices with a ratio of 50, but NEVER use hFE for a switch. …

Even an NPN would always be only with 1K to 10K to 15V. Maybe 33K is OK or no 10k pull-up needed if using logic levels. REF Summary: Change PNP to NPN Remove 10K for any logic level 1V to 5V ON. Inv …

traditionally it would be called a Common Source JFET driver to a Common Base (wide BW) NPN amplifier. The vertical configuration is also a cascode.. It is “open loop” and may be improved with negativ …

No. Vbc is never biased forward in linear more and is always less than Vbe when saturated and Vbc >|-1| for better linear mode, for lower THD. That means Vce>2V for better linearity.
