Showing of 10 reviews. I wanted to build one again recently and all Datashret had a was a Schottky diode with a Vf of around 0.

Back when I was younger I got a crystal radio set kit which included a 1N34A Ge diode as far as I can remember, I don’t have it anymore. Sold by Chanzon and ships from Amazon Fulfillment. See more product details. Amazon Music Stream millions of songs. Something we hope you’ll especially enjoy: Datasehet 1N34A conducts much smaller currents with a lower Vf.

Image Unavailable Image not available for Color: It may well be the diode that is causing problems. Try locating an actual crystal earpiece and give it a go. As you can see from this diagram from here. Once you have a working receiver, datasheer can try using the piezo buzzer and see what it does and how it changes things – but that is an experiment for AFTER you have a working receiver.


Pack of 20 Pieces Chanz I think that “a piezo buzzer” today isn’t comparable to a crystal earpiece.

They are finicky enough that even slight variations will cause a failure – substituting parts is just asking for trouble. It is my understanding that Ge diodes were the 11n34 for crystal sets because their low Vf does not load the tuned circuit. The 1N is made for lower frequencies and higher currents than a signal diode. Top Reviews Most recent Top Reviews.

Amazon Restaurants Food delivery from local restaurants. Used on my crystal radio with minimal success.

Germanium Diode 1N34A

A piezo buzzer is meant to BUZZ at a particular frequency. Fast shipping and just what I needed for my project. The typical load on a 1N34A diode in a crystal radio is a crystal earpiece with an impedance of 20kOhm. Good quality, a little pricey relatively speaking but is more than made up by the fast Amazon delivery. A point contact germanium diode is much more sensitive and effective. It lists Vf as 1V at 5mA It’s never this black or white: Please refer to image for the specification datasheet.

From my own experience in building crystal radios, you would be well advised to build the first one using exactly the parts recommended and exactly the schematic of someone who has built one successfully. Please make sure that you are posting in the form of datadheet question.

Perhaps I am misunderstanding the datasheet? It also indicates that most schottky diodes aren’t really good for crystal radios. Used this product for crystal radio works great. East Dane Designer Men’s Fashion. There was a problem filtering reviews right now.

Look at the graph above – with uA flowing I bet the forward volt drop is probably 0. Of course the low forward drop is a welcome feature when designing with lower signal voltages.

This is not a point contact diode. They work like Germanium diodes are supposed to– they allow current flow in one direction only and have a low forward voltage bias compared to silicon diodes. Used these for making pedals. See questions and answers.

Please try again later. Also worth noting is that Vf is dependent on temperature. Would you like to tell us about a lower price? Another thing to keep in mind is that they don’t have fanstatic range. In reponse to comment: Add all three to Cart Add all three to List.

I’m looking forward to future experimentation with these in radio circuits. Look at this one:
