Discussion Overview
The discussion revolves around finding alternatives to the 1N4148 diode that are smaller in size for use in compact circuit designs. Participants explore various options, including leaded and surface mount diodes, while considering cost and physical dimensions.
Discussion Character
- Exploratory
- Technical explanation
- Debate/contested
Main Points Raised
- One participant seeks a general-purpose diode smaller than the 1N4148, emphasizing the need for compact components in their circuit design.
- Some participants suggest that the 1N4148 is already one of the smallest leaded diodes available and question whether standing them on end would help reduce footprint.
- Another participant mentions that surface mount parts can be obtained cheaply, although they may require purchasing in bulk, and compares prices of 1N4148 and surface mount options.
- A participant introduces the BAW56 as a common anode diode array and inquires about common cathode alternatives.
- One participant suggests BAV-99s as traditional SMT substitutes for the 1N4148.
- Discussion includes references to standard packages like SOT-23 for diodes and notes that while smaller packages exist, they may be more challenging to solder.
Areas of Agreement / Disagreement
Participants generally agree that the 1N4148 is a small diode, but there is no consensus on whether suitable alternatives exist that meet the size requirement without incurring high costs. Multiple competing views on diode options and pricing are presented.
Contextual Notes
Participants express varying opinions on the cost-effectiveness of surface mount versus leaded diodes, and there are unresolved questions regarding the availability of common cathode diode arrays.
