Cedric: I know you said "5KE36CA." Motorola, Fairchild, and some others make a zener transient suppressor 1.5KExxCA. The CA suffix makes it bidirectional. Actually, Motorola is no longer in the business. On Semiconductor (www.onsemi.com) sells t

Hi Robert, Try looking at www.marsport.demon.co.uk/smd/ This site contains a list of html files with all marking codes known at this moment. Your example of a transistor with marking code 8A can be a 3V3 zener diode or a npn general purpose transi

On average there are about 3 parts per board that get hand placed (x24 is 72 parts per panel). One of these parts is a big 1W resistor that cannot fit on our axial machine. We also have a Zener Diode that needs to be hand placed because its leads are

A couple of things i would try: 1. Does function 30 give you a nozzle height that is repeatable. The number should be around 200.....+/- 20 or so. 2. I would change the z-rod because the spring could be worn out and when the vacuum turns on....it ca

Chances are you are using this as a 2.5V voltage reference for the feedback on your regulator. One thing that isn't clear is exactly what failure you are seeing. Please specify the nature of the failure. Is your power bus out of spec? I really ca
