I always thought there was only two pins on a 1Nxxxx part.... Anyhow, regular SOT-23 zeners only have 3 pins. Pins 1 and 3 typically. At least the ones I've seen in Digikey. Pin 1 anode, pin 3 cathode. True for other SOT-23 types of diodes too, like MMBD4148.

It shows pin 1 = cathode, pin 4 = anode.

Connect the 1k from the supply pos to pin 3. Connect pin 1 to PS GND. Connect your multimeter across pins 1 and 3. I'm right, you should have about 7.5V. The "5236" part of the reel number seems to me to be the 5236 of like 1N5236. Note: orient the device such that it is live bug (pins down and away from you), and the side with both pins towards you. Pin 1 is on the left towards you, pin 2 is on the right towards you, and pin 3 is all alone away from you.

The reel is marked with a Rohm part number RSZ5236B T116, the individual devices are marked 8L on the long axis and 51 across the short axis, anyone that can help ID what they are, I have 3,000 of the little suckers and will send you some. I guess if this fails it will be a good excuse to get a M3 transistor checker. 73 Doug W7RDP ______________________________________________________________ QRP-L mailing list Home: http://mailman.qth.net/mailman/listinfo/qrp-l Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[EMAIL PROTECTED] ______________________________________________________________ QRP-L mailing list Home: http://mailman.qth.net/mailman/listinfo/qrp-l Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[EMAIL PROTECTED] ______________________________________________________________ QRP-L mailing list Home: http://mailman.qth.net/mailman/listinfo/qrp-l Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[EMAIL PROTECTED] ______________________________________________________________ QRP-L mailing list Home: http://mailman.qth.net/mailman/listinfo/qrp-l Help: http://mailman.qth.net/mmfaq.htm Post: mailto:[EMAIL PROTECTED]
