Discussion Overview

The discussion revolves around identifying a diode with a low forward turn-on voltage that features through-hole termination. Participants explore various diode models and their applicability, particularly in the context of initial design on a breadboard.

Discussion Character

  • Exploratory, Technical explanation, Debate/contested

Main Points Raised

  • One participant inquires about specific diode models suitable for low forward turn-on voltage and through-hole termination, mentioning the BAT54 Schottky diode series as a known option but noting its surface mount limitation.
  • Another participant asks for clarification on the application and suggests the possibility of using an op-amp in an active circuit.
  • Links to product selection guides and datasheets are provided by a participant, indicating resources for finding suitable diodes.
  • A suggestion is made to use an adapter for surface mount components if a suitable through-hole substitute cannot be found.
  • Participants mention the BAT48 and BAT85 diodes as alternatives that meet the criteria of being through-hole and having similar characteristics to the BAT54.
  • Another participant notes that the 1N5711 diode has an IV curve nearly identical to that of the BAT48, suggesting it as a comparable option.

Areas of Agreement / Disagreement

Participants present multiple diode options and suggestions, but there is no consensus on a single best model. The discussion includes various viewpoints and alternatives without resolving which is the most suitable.

Contextual Notes

The discussion does not clarify the specific application for the diode, which may influence the choice of model. There are also no detailed comparisons of the electrical characteristics of the suggested diodes.

Who May Find This Useful

Individuals seeking low forward turn-on voltage diodes for breadboard applications, electronics hobbyists, and those designing circuits that require through-hole components.

Hi.

I'm wondering if anyone knows the model number of a diode, which has a low forward turn on voltage, and has through-hole termination.

I am aware of the BAT54 Schottky diode series. The turn on voltage is as low as ##0.2 V## for some models, but the problem is they are surface mount components. I intend to use a breadboard for an initial design, so I need through-hole specifically. I may consider surface-mount if I can get my hands on a PCB later on.

If you happen to know any good products, please let me know the model number.

Thank you.

What is the application? Can you fashion an active circuit using an op-amp?
 
If you need a specific part that you can't find a suitable through hole substitute then use the real deal on an adapter:

This is the brand I usually use but many others exist.

BAT48 (DO-35 package) and BAT 85 (DO-34 package) are both through hole and have very similar characteristics to the part you mention. Plus, they're widely available from all the usual distributors.
 
1N5711 has nearly identical IV curve to BAT48
