The two types of standard transistors are PNP and NPN which differs in circuit symbols. The layers of semiconductor material used to make the transistor are denoted by the letters. To keep a straight ...

The ISL73096EH is a radiation hardened ultra high frequency NPN/PNP transistor array. It contains three NPN transistors and two PNP transistors on a common substrate. The device covers all of the ...

Matching a sensor interface with a programmable logic converter or controller hardware that can accept only one type of input—npn or pnp—can be difficult. The last-stage modification circuit described ...
