I change the circuit simulation and values

What is the input? What are you trying to build? Have you simulated something yet? \$h_{fe}\$ is small signal gain, and I don't see any small signal here. | |
| Oct 10, 2021 at 6:59 | comment | added | Citi | mkeith Yes, I need to figure out how to design my desire circuit using the smd's NPN 2N2222 and PNP MMBT2907A transistors to account for Beta values, and still get at least 100ma in the PNP IC current. | |
| Oct 10, 2021 at 6:33 | comment | added | user57037 | Beta, the gain of the transistor, varies quite a bit. There can be differences from unit to unit. Differences with temperature. Differences with collector current, etc. It is not good to assume that beta is a specific number. You have to design your circuit so it works over a range of Beta values. | |
| Oct 10, 2021 at 5:27 | comment | added | Citi | DKNguyen what I mean is that if a transistor max IC=600ma, if we allow more current than 600ma the transistor might stop working | |
| Oct 10, 2021 at 4:40 | comment | added | DKNguyen | ""we know that at 700ma the transistor will stop functioning," This is wrong. Start from the beginning. | |
