Avtech AVR-EB4-B, Instructions Manual

The instrument and the DUT will not be damaged if the diode is installed with the
incorrect orientation (i.e., with the anode and cathode reversed). However, incorrect
waveforms will be generated.
The procedure for inserting most axial and TO-220 packages is straightforward. Simply
insert the DUT between one of the Anode pin sockets (in the blue area above) and one
of the Cathode sockets (in the red area above). Select the sockets with the most
appropriate hole size, and try to minimize all lead lengths, to minimize parasitic
inductance.
This jig will also accommodate a number of TO-3 configurations, outlined below. If the
case is connected to the anode, and the pin(s) are used for the cathode, the
arrangement shown below must be used:
If the case is connected to the cathode, and the pin(s) are used for the anode, the
arrangement shown below must be used:

This spring pin must
contact the underside
of the case. It provides
the anode connection.
The cathode pin of
interest must be inserted
into this socket. For dual-
diode devices, rotate the
TO-3 package so that the
desired diode cathode is
inserted here.
This socket and spring
pin provide mechanical
support only. They are
not electrically active.
For TO-3 packages
with Case = Anode
