WebSep 7, 2024 · A PNP transistor can be used in the same way as an NPN transistor. The difference is that in PNP, the load is always connected to the ground and the PNP will be … WebJan 16, 2024 · In a PNP transistor this is just configured the opposite way. The entire thing is enclosed in a resin to protect the internal materials. With an NPN transistor we have the main circuit and the control circuit. Both are connected to the positive of the battery. The main circuit is off until we press the switch.
WebAC128 PNP Germanium. NOS from 1970's. Choose your hFE range, higher number is higher gain. *Note, germanium is temperature sensistive, these were measured in a warehouse ~70 ° F. Tested with RG Keens method. Anything unstable was rejected. Leakage is below 300uA unless otherwise specified. These hFE ranges are meant to be ballpark ranges and ...
