Charles Hansen said:VP01 series is still listed in three variants. VP0104 is 40 volts, VP0106 is 60 volts and VP0109 is 90 volts.
VN13 is not listed, but VN0104 (40 volts) and VN0106 (60 volts) are still listed and these are the complements for the VP01 series.
The part numbers you gave are probably from the schematic, which may not be accurate. You should be able to read the correct part number from the actual transistor.
If you still get stuck, I may have an old Supertex data book at work and I can check tomorrow.
Charles Hansen said:OK, I found an old data book. The VN13A came in six variants -- three different voltages (40, 60, 100) and two different packages (TO-92 and TO-39). So the full order numbers were:
Where "x" represents the package. A "2" indicates a TO-39 and a "3" indicates a TO-92.
If you can figure out which voltage and package you need, then you will have the full part number. Then do a Google search and you can probably find a distributor with some stock (NOS).
peranders said:I have 10-20 of each or similar laying around but I'm not sure where.
Can you read the text? Do they have the same package?
BTW: I have also the original databook.
