Where to use NTE159M

The NTE159M is a general purpose PNP transistor that is available in TO-18 Package. The transistor has its complementary NPN version called the NTE123A, the datasheet of both can be found below. Since these form a complementary pair they can used in designs where both a NPN and PNP transistor or same characteristics is required. Push-Pull circuits, Class B amplifiers, H-bridge circuits are few examples circuits in which a complementary transistor is required.

The NTE159M has a low collector saturation Voltage of 1V and a can switch at high frequencies making it suitable for amplifier designs. You can also check out the 2N2907 transistor if you are looking for an alternate package for this NTE159M transistor, the 2N2907 is available in standard TO-92 package as well.



  • General purpose switching
  • Class B amplifier designs
  • H-bridge circuits
  • Push-Pull configuration circuits
  • Medium-speed switching
  • High frequency amplifiers
