Off-line flyback uses HV transistor in common-base configuration

OK, so I get a press release (pdf) from those wonderful folks at CamSemi, AKA Cambridge Semiconductor. It talks about their C2163 off-line switcher chip (pdf). The press release says: “…the BOM cost ...

Collector-Base-Emitter Pin Identifier of Transistors

The circuit has been designed for transistors to determine whether the pin is emitter, base or collector as well as the type if NPN or PNP polarity, and can also be used in testing diodes. 4011 – a ...

Beginner Concepts: MOSFETs

[Moser’s] introductory guide to MOSFETs serves as a quick introduction for those unfamiliar with the parts. They fill a similar role as a bipolar junction transistor like the 2N2222, making it ...
