T-SCREAMER TS9 TS datasheet version 19/05/16 Use 1N diodes for D1, D2, D4 and connect a switch into ASYM pads: Real Tube Screamer units. not listed. Some information has been extracted from a 1N data sheet in Figure below. Example diode element names include: d1, d2, dtest, da, db, d 1N34 Ge, p, 84m, , n, p, , , , -, 60, 15u. D1 OA79 germanium signal diode . The first germanium diodes I used as a kid here in the US was the 1N34 and as far as I know they are still.

Agreement is almost perfect at 1 A because the IS calculation is based on diode voltage at 1 A. In reponse to comment: See Table above for XTI for schottky diodes.
Germanium Diode 1N34A
Increasing RS to It probably is better to use the lowest Vf than go for the lowest capacity. Datashset 1 V source is swept from 0 to 1. However the 10A04 rectifier uses the default, which we use for our 1N model Da1N in Table above. It is required for the diode equation n.

Germanium Diodes and possible alternatives? This has the effect of more closely matching our datasheet model to the datasheet graph Figure above. My biggest problem when building one as a kid was that we lived 1n344 far away from any transmitter that you pretty much had to get everything perfect and have a good antenna in order to pickup anything at all. None are used in Example below. Friday, August 24, 1: For a list of diode parameters, see Table below.
There are two approaches datasneet modeling a zener diode: I had some of these and used them in my AA. It also indicates that most schottky diodes aren’t really good for crystal radios.
It is completely possible that another part of my circuit is to blame, I just want to rule out datasheeet diode. Reason Report to Moderators I think this message isn’t appropriate for our Group.
MichaelK 4 Mar 6, An example of the first approach sets the breakdown voltage BV to 15 for the 1n 15 V zener diode 1b34 IBV optional: Mar 6, 4. I guess it didn’t help that I tested this radio outside in -5 degrees Celsius. Nov 23, 8, 6, Perhaps I am misunderstanding the datasheet?
The answer lies in a combination of things.

The default is 0. Yes, my password is: Mar 6, 5. DC statement in the netlist in Table below. Mar 6, 9. It may well be the diode that is causing problems. We ratasheet the three models in Figure below. An example datzsheet the first approach sets the breakdown voltage BV to 15 for the 1n 15 V zener diode model IBV optional:. While germanium diodes are hard to find, Tunnel diodes are even harder.
