18. Diode Replacement

Question.5

A circuit originally uses a single signal diode in an SOT-23 package on a signal line. The exact diode is unavailable, so it is replaced with 4878-BAV99TR-ND (Digi-Key part number), which has the same electrical specifications but contains two diodes in a single SOT-23 package.

What must be checked before using this replacement?

The BAV99 will not work because it has two diodes
Only one internal diode should be used and the pin connections must be correct
The BAV99 will draw more current because it has two diodes inside
Any dual diode can replace a single diode without changes
