The 1N34A Germanium diode is an old standby in electronics. Widely used for detecting the rectifying efficiency or for switching on a radio, TV or stereo etc. Item no. 1N34A. Jan 26, 2014 · The schematics with diodes in series allows comparing voltage drop in both cases: Germanium vs Schottky + series resistor for a given range of current. Simulation is repeated for Schottky diode with different resistor values. Series resistor is entered as parameter Rx from 5 to 500 ohms. Mar 24, 2008 · If you can locate another source that supplies replacement parts for radio/TV repair they will likely have a 1N34 diode or a direct replacement. You could also use a small signal Schottky diode as a replacement, as their forward voltage characteristic is more in line with a 1N34. I also second the comments of the first answer. A point contact diode in a DO-7 type package employing N-form Germanium and gives an efficient and excellent linearity when used in TV image detection, FM detection, radio AM detection, etc. Symbol Description 1N34A Unit Conditions PIV Maximum Peak Reverse Voltage 65 V IR=1.0mA IFSM Peak Forward Surge Current 500 mA t=8.3ms, half sine VF Maximum Instantaneous Forward Voltage 1.0 V IF=5.0mA 30 VR=10V IR Maximum Reverse Leakage 500 µA VR=50V CJ Typical Junction Capacitance 0.8 pF Measured at 1MHz,Vr=0V I realize the difference between the two diodes (germanium vs. silicon), but have been using 1N4148s as replacements for years without any issues. Mar 18, 2012 · I agree with the 1n270. I would socket it and try others. I find that sometimes you can hear a difference and sometimes you can't. This could be a good opportunity to see for yourself.

Just looking at the specs, 1N34 is rated for 60 peak reverse volts while 1N60 is only rated for 40 prv.<P>1N60 has a very small shunt capacitance (1pf) while 1N34 is not specified.<P>So maybe a 1N60 would be preferred for a video detector...but a selected 1N34 could be as good.<BR>I have gotten the impression that almost any germanium diode gets tossed in envelopes marked 1N34 recently.<BR ... A point contact diode in a DO-7 type package employing N-form Germanium and gives an efficient and excellent linearity when used in TV image detection, FM detection, radio AM detection, etc. Aug 28, 2013 · The 1N34 data sheets are very sparse. None that I've seen have v-i curves, and they spec current of a few mA at ONE VOLT forward. Being a point contact device, capacitance is low and series resistance is high. I like the Skyworks SMS7621. 0.25 pF, around 300 mV at 1 mA, and way less series resistance than a 1N34. Mar 17, 2005 · Is the NTE109 a comparable replacement for the 1n34a? I am trying to build a simple RF probe and can't find a 1N34A localllay, but can get an NTE109, just wondering if the spaces are as good. 1N34A 1N34 Germanium Diode DO-7; 1N34A 1N34 Germanium Diode DO-7. 1 Review | Add Your Review. $0.28.

I realize the difference between the two diodes (germanium vs. silicon), but have been using 1N4148s as replacements for years without any issues. Diode 1N34A General Purpose Germanium. Image is representative only ... 1N34A Germanium Diode. Have a look at Circuit Specialists' lineup of germanium diodes, which allow electric current to pass in one direction while blocking current from traveling in the opposite direction, enabling you to convert alternating current to direct current and extract modulation from radio signals in radio receivers.

Germanium Diode Test A germanium diode is a vital component in the construction of crystal radios, and the quality of the diode will determine how well the radio operates. If you are new to building crystal radios, then the first thing to learn is how to distinguish between germanium and silicon types of diodes. (Pack of 20 Pieces) Chanzon 1N34A 1N34 Germanium Diode 50mA 65V DO-35 (DO-204AH) IN34A IN34 Axial for TV FM AM Radio Detection 4.4 out of 5 stars 37. $5.99. Can 1n60 substitute 1n34A as germanium clipping diode with similar results? That's the only GE diode they have around here. ... it is a matter of personal taste. 1n34 ... Diodes - cross referencing? This is a tough nut to crack, and when I left the question on the diyaudio tube forum, I did not get the answers I needed. Days of asking and searching left me with more questions that answers. 1N34A Datasheet, 1N34A Germanium Diode Datasheet, buy 1N34A Diode
