Description: Schottky diodes are known for their low forward voltage drop and a very fast switching action. This 1A 40V Schottky diode is ideal for use with motor drivers such as the L298N.

  • It would be useful to mention in the product description that these are 1N5819 diodes, since the datasheet covers 3 different diodes. Since I’m primarily interested in Vf, and this one has the highest Vf of the 3.

  • Love it how the pic is all bent and worn :)

  • can I use it with a PWM of 80% duty cycle ? will it keep the PWM signal ? and the power flowing trough it will be only 20 mA and 5v is it ok ? Where can I find an exelent tutorial about diodes and there use ?

  • 1A isn’t a lot. I need a diode 1.3A , 25VDC, low Vf for use with a small solar panel. I found VSB15L45-M3/54, a 15A, 45VDC Schottky diode, axial mount (SMD is ruling the world increasingly ;-( ) by Vishay, but nobody stocks it, or will order less than 1000 of ‘em.
    Any suggestions?

    (I’d suggest Spark sell ‘em because they’ll cover LOTS of jobs and have a handy form for projects)

  • It helps me to remember the function of Schottky diodes by always calling them Schottky Flyback diodes. These are also known as inductive spike snubbers on the activation coil of relays.

  • At 100 units for $12, this is cheaper than Digikey. :)

  • is it the 1n4001?

    • You could probably use the 1n4001 if you are doing something in Eagle, because these two parts are really about the exact same size, but this is the 1N5819 Shottky Diode, it has less forward voltage drop and is capable of switching at a much faster rate than your standard run of the mill rectifier diodes.

  • what part on Sparkfun’s eagle library should i use?

  • The link to the datasheet doesn’t work. I’ve never understood why people use javascript to link to pages or files either.

    • It wasn’t supposed to be javascript, something weird happened. It’s fixed now.
