Note that the difference in collector current to emitter current during this time period goes through the transistor base. The transistor remains on and the magnitude of the collector current is ...

Transistors want current control, and your microcontroller GPIOs attempt to put out a given voltage. You need a voltage-to-current transformer, otherwise known as a resistor. (See Ohm’s law .) ...

NPN transistors are key components in electronics, used as switches or amplifiers with three legs: base, collector, and emitter. Thyristors are semiconductor switches with three legs: gate, anode ...

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 ...

I now get why they drove the transistor common-base. Yanking on the emitter reduces the Miller effect. It takes less gate drive to charge the gate of a LV FET with a Miller swing of maybe 10 V, ...

Strategy Analytics: Base Station Power Amplifier Transistor Market Expected to Exceed $1 Billion in 2014. LDMOS Remains the Dominant Transistor Technology February 03, 2011 11:11 ...

A new generation of high-voltage gallium arsenide power amplifier transistors is designed to substantially boost the efficiency of 3G cellular base stations, reducing energy costs while allowing ...

Infineon has introduced a family of high power ldmos transistors for use in broadband wireless network base stations. With power levels of up to 300W and video bandwidth exceeding 90MHz, the ...

The Allentown chipmaker unveiled 21 new transistors for use in cell phone base stations. Agere is targeting the makers of power amplifiers used in second- and third-generation cell phone base ...

Nexperia has announced a series of 500mA dual bipolar transistors that include base resistors within the 2 x 2 x 0.65mm package – there is a choice of SOT1118 (DFN2020-6) or AEC-Q101 automotive ...
