    Forward Voltage of Schottky vs Temperature

    Hello, I've been looking for a Schottky diode which experiences an increase in forward voltage through the normal operating temperature range (-40C - 125C). I've only seen diodes in which the forward voltage decreases as temperature increases. If such a device existed, I could use it for a...

    LED reverse breakdown voltage

    Hello, I'm wondering if anyone has any experience with subjecting an LED to a reverse voltage that is higher than its Vrbd. The specific question would be this: How long before the LED would see catastrophic failure? Most LED datasheets that I've read specify a Vrbd of 5V. Hypothetically...

    Ceramic Capacitor Polarity

    Hello, I've got a little problem with a multi-layer ceramic capacitor that I'm trying to use. I'm using some as filter capacitors on a buck regulator circuit. The noise is filtered just fine, but it seems that too much current is conducting through them during their charge cycle (1st half of...
