It really shouldn't be that hard to find a PNP BJT that doesn't hiss like a snake...... I have searched my favorite vendors (Digikey, Mouser, Tayda) and they do not seem to think NF is worthy of their search tools. Nor does ONSemi, my goto for reliable data sheets and a broad spectrum of parts but lousy search tool; also TI. I can find NPNs with NF data, but no PNPs. Is it not possible to make a low noise PNP?
I am looking for a small signal device, VCEo about 45V, Ic about 150-200mA, Hfe in the 150+ neighborhood, power 500-750mW, and NF<2. Most datasheets do not even bother to tell me the NF. I presume this means it must be pretty high, as in >50 (I learned long ago, if you are not proud of it, don't print it). Am I mistaken?
I found mention on this site of a number of low noise devices. They are either obsolete or made of unobtainium. I am willing to pay a 10% premium for what is otherwise a 2N3906, 10,000% is not in my budget.
Sorry you had to read my rant; I just didn't want anyone to think I hadn't done my due diligence before posting my plea: What is your favorite small signal, low noise PNP that is not obsolete and readily available?
