Hello
Need some help from your electronic guys
Can I used two 1n4148 diods instead of one BV199 ?

Re: Substitute for Diode BAV199
In what circuit and in which position is this for?

Standby alert
“There are four lights!”
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer in Somerset later in the year
Not as many MTXs as Dave!

Re: Substitute for Diode BAV199
Looking at the data sheets, it seems to me that there are two significant differences between the BAV199 and a pair of 1N4148:
If, however, the BAV199 is used just because it is a convenient small package for two diodes, then probably OK. The voltage and power ratings of the 1N4148 should be adequate.
- The BAV199 diodes have a reverse leakage current of only 5nA, as opposed to 25nA for the 1N4148.
- The two diodes in a BAV199 will be very closely matched, and thermally coupled, so will have almost identical characteristics.

Bill and Mark, I will bring the schematics for the Memofest, then you can help me to understand it
Its quite simple, circuit.
