Manufacturing companies, particularly those that mass-produce electronic circuits, work pretty much around bipolar junction transistors, like PNP and NPN. However, choosing between these two BJTs ...

Covering the operating voltage range from 20V through to 100V the Zetex bipolar transistors are able to drive MOSFET gates faster and more efficiently than CMOS IC alternatives and being immune to ...

Just like with NPN and PNP transistors, there are N-FETs and P-FETs. N-FETs are like NPN transistors – the gate pin needs to have higher voltage than the source pin for the FET to open.

The circuit monitoring the positive rail replaces npn with pnp devices. Best results are obtained using inexpensive dual transistors and 1% resistors for setting Iref and for Re1 and Re2.

BUFFALO, N.Y. — University at Buffalo researchers are reporting a new, two-dimensional transistor made of graphene and the compound molybdenum disulfide that could help usher in a new era of computing ...

This ensures an output stage that can directly drive a relay with a 22-V switching voltage from a 24-V power supply. The transistors used (a 2N3055 npn and 2N2955 pnp in TO-220 packages) are ...

Lauded as the first miniature bipolar NPN/PNP transistors available in SOT23FF packages, the ZXTN19020CFF and ZXTP19020CFF 20V devices measure 2.5 mm x 3 mm with an off-board height of 1 mm.
