Soms wanneer de spanning die over de emitter wordt … WebAn NPN output would go between ground and resistor. I'm saying this because I'm unsure about what you are saying in your comment. I think you need to be clear about what you do understand and don't understand. The same circuit suits either PNP or NPN. A dry contact can replace PNP or NPN but you need a power rail for a dry contact. \$\endgroup\$
Web26 sep. 2024 · To turn on the PNP, you pull down the 1K with the NPN, and draw 8mA to GND. With a PNP gain of x100, it can support 8 x100mA going to LEDS...and you only need 100mA...so it turns ON hard..which is good as a switch. … Web15 mei 2015 · The 2N3055 power transistor was NPN, at a time when PNP transistors of the same power were simply not available (115W I think, later pushed to 150W). That led to the "output triple" - a combination of 3 transistors that could replace either NPN or PNP output transistors, with the power handled in either case by the 2N3055.
