High Idss 2SK170GR?
I measured a bunch of 2SK170GR for Idss this afternoon and am a little puzzled. First, I am an electronics novice, so please forgive my ignorance.
My milliammeter has blown its fuse and I do not have a replacement in stock yet. So I decided to measure the voltage across a 100R resistor between the positive terminal of a 9V battery and the drain. I shorted the gate and source and connected them to the negative battery terminal.
My voltage readings across the resistor were in the 0.3 - 1.3V range, suggesting an IDss of 3 - 13 mA, with most clustering around 12-13 mA. This is pretty out of range for GR parts. Is there something wrong with my technique, my parts, or does Toshiba play a little fast and loose with their parts labeling?
(my first post)
Are you sure that the SK170GR are genuine Toshiba parts?
Genuine Toshiba parts are within specs, no doubt.
There are a lot of counterfeiting parts supplied these days.....
I have no certainty that these parts are genuine toshiba. I bought them from futurlec a few months ago. They look like any other 2sk170 I have used in the past, but who knows. It may be worth following up with futurlec Thanks for your response.
