By applying a reverse-bias voltage between gate and source, pinch-off of the channel should be apparent by an increased resistance reading on the meter.

Of course, if you know beforehand which terminals on the device are the gate, source, and drain, you may connect a jumper wire between gate and source to eliminate any stored charge and then proceed to datasgeet source-drain continuity with no problem. Quote of the day. Published under the terms and conditions of the Design Science License.


Testing a JFET with a multimeter might seem to be a relatively easy task, seeing as how it has only one PN junction to test: Remember from the datasheft section how a stored charge across the capacitance of the gate-channel PN junction could hold the JFET in a pinched-off state without any external voltage being applied across it?

PyVisa connects a computer to the measurement instruments and Since the JFET channel is a single, uninterrupted piece of semiconductor material, there is usually no difference between the source and drain terminals.

The conductivity of the foam will make a resistive connection between all terminals of the transistor when it is inserted.

A good strategy to follow when testing a JFET is to insert the pins of the transistor into eatasheet foam the material used to ship and store static-sensitive electronic components just prior to testing.

9ns20t resistance check from source to drain should yield the same value as a check from drain to source. This resistance should be relatively low a few hundred ohms dataasheet most when the gate-source PN junction voltage is zero. Testing continuity through the drain-source channel is another matter, though.
