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. Add all three to Cart Add all three to List.

They work like Germanium diodes datashedt supposed to– they allow current flow in one direction only and have a low forward voltage bias compared to silicon diodes.

The price was good too.

Amazon Second Chance Pass it on, trade it in, give it a second life. You need the crystal earphone to avoid loading the tuning circuit and to keep the Vf low enough for the diode to demodulate the signal. Showing of 10 reviews. My biggest problem when building one as a kid was that we lived so 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.

Used on my crystal radio with minimal success. Please try again later. East Dane Designer Men’s Fashion. Fast shipping and just what I needed for my project. I guess it didn’t help that I tested this radio outside in -5 degrees Celsius.

Thank you for your answer and the clarification about why I need a low Vf and crystal earpiece. Learn more about Amazon Prime. It is my understanding that Ge diodes were the choice for crystal sets because their low Vf does not load the tuned circuit.

Image Unavailable Image not available for Color: The 1N34A conducts much smaller currents with a lower Vf.

Something we hope you’ll especially enjoy: The familiar DO case requires no confusing mental adjustments. They were shipped quickly as well, which is always appreciated. Customers also shopped for. ComiXology Thousands of Digital Comics. AmazonGlobal Ship Orders Internationally. This is not a point contact diode.


I am pleased with the delivery time, the product packaging, and the product itself.

Alexa Actionable Analytics for the Web. Buy the selected items together This item: A buzzer is made to work specifically at a particular frequency. Whether and how well it works at other audio frequencies is anybody’s guess. The typical load on a 1N34A diode in a crystal radio is a crystal earpiece with an impedance of 20kOhm.

As you can see from this diagram from here, The 1N34A will conduct 0. I heard no sound from it through a piezo buzzer pressed against my ear and figured it was maybe because of the diode, so 1n334 looked around for the datasheet for the 1N34A to read its characteristics.
