It lists Vf as 1V at 5mA It’s never this black or white: It also indicates that most schottky diodes aren’t really good for crystal radios. Email Required, but never shown.

1N34 Datasheet

Please refer to image for the specification datasheet. The 1N34A conducts much smaller currents with a lower Vf. Thanks again for your replies. English Choose a language for shopping.

Please make sure that you are posting in the form of a question. Good quality, a little pricey relatively speaking but is more than made up by the fast Amazon delivery.

Used this product for crystal radio works great. It all comes back to building the receiver right with all parts as specified, then you can start experimenting with buzzers as earphones or using other diodes, etc. Try locating an actual crystal earpiece and give it a go. Interesting you mention temperature. A point dxtasheet germanium diode is much more sensitive and effective.


I’m looking forward to future experimentation with these in radio circuits. The familiar DO case requires no confusing mental adjustments. This ties back in to what I said about building the first one right with all the right parts.

Good lead solderability, but I first cleaned the leads as a matter of course.

1N34A – 1N34A Germanium Diode Datasheet

For anyone feeling shakled to the sky-high silicon band gap, this is the diode to go with! I heard no sound from it through a piezo buzzer pressed against my ear and figured it was maybe because of the diode, so I looked around for the datasheet for the 1N34A to read its characteristics.

Post as a guest Name. 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. Don’t see what you’re looking for? Since a crystal earphone draws very little current, Vf is also lower.

Used on my crystal radio with minimal success. By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service. They both use a piece of piezoelectric crystal to work. A buzzer is made to work specifically at a particular frequency.

Perhaps I am misunderstanding the datasheet?


Amazon Second Chance Pass it on, trade it in, give it a second life. Datashfet Reviews Most recent Top Reviews. According to that site, you will need a bias current for most schottky diodes to get good performance.

The 1N is made for lower frequencies and higher currents than datawheet signal diode. Image Unavailable Image not available for Color: With a lower If, Vf is also lower.

AmazonGlobal Ship Orders Dztasheet. 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. Another thing to keep in mind is that they don’t have fanstatic range. You need a low Vf because of the modulation scheme, not to avoid loading the tuning circuit.

I am pleased with the delivery time, the product packaging, and the product itself. Sold by Chanzon and Fulfilled by Amazon. Once you have a working receiver, you can try using the piezo buzzer and see what it does and how it changes things – but that is an experiment for AFTER dahasheet have a working receiver.
