1N34A Diode Explained / Description

If you see a glass body diode which is transparent in your RF electronic appliances such as radios and TVs etc. it is most likely a 1N34A diode. 1N34A is a famous germanium diode designed to be used in radio and RF circuits. Mostly is used in the detector circuits of these appliances to detect RF signal on the first stage and convert them in to a DC signal which is then preamplified and amplified by the circuitry.

The diode has many features such as its has high mechanical strength glass body due to which it can survive if it has to face a high physical force in any situation, it has lower leakage current, it can withstand on high voltage, it has lower leakage and small reverse current, extremely suitable for FM band region etc. So if you are using a germanium diode for signal detection purposes then 1N34A can be a good choice.


Where We Can Use It

The 1N34A has many uses. It can be used in wide variety of very low level signal detection purposes. Whether it is a radio, TV or any other similar appliance 1N34A can be a most important component of it.

Safe Operating Guidelines / Absolute Maximum Ratings

To get good and long term performance make sure to follow these safety guidelines when using 1N34A diodes.

  • Always check the pinout carefully to use in your circuit or design.
  • Do not drive it to its absolute maximum ratings and always stay atleast 20% below.
  • Do not drive load of more than 40mA.
  • Do not drive load of more than 50V
  • And always operate or store the diode at temperatures above -55 °C and below +75.
