So the drain to source voltage and the drain current can be considered constant.

2SK30 Datasheet

Reason Datashest to Moderators I think this message isn’t appropriate for our Group. BTW I cut the C1 and C2 input cap leads, as they are solid aluminium electrolytics I will replace them, just to make sure, so no influence from there. NEC Corporation assumes no responsibility for any errors which may appear in. Transportation equipment automobiles, trains, ships, etc.

NEC devices are classified into the following three quality grades:. I could not find any graphs about this 2SK30Y behavior Now, as the schematic calls for a suggested drain voltage of 6.

The Specific quality grade applies only to devices developed based on a. On Wed, Nov 18, at 6: The new topic will begin with this message. So, taking the delta-Vgs from 0V to No license, either express, implied or otherwise, is granted under any patents, copyrights or other. The Vgs affects operating range but it otherwise not important; usually low Vgs JFETs are used and the drain current is set so that the offset from the input to the output of the composite amplifier is zero volts.


I chose the 2SK30 since it’s input capacitance is closer to the original 2SK and the scope seems to be working fine. While NEC Corporation has been making continuous effort to enhance catasheet reliability of its semiconductor devices.

NEC Corporation assumes no responsibility for any losses incurred by the customer or third.

Computers, office equipment, communications equipment, test and measurement equipment. Ian van der Neut. Typically the 2sj30 drain current will be 5 to 10 milliamps and from that it is possible to lookup the Gm which is what I did. When particular JFETs are recommended for audio applications, that’s because of low noise, not poor frequency response.

I can find different gm values on this plot. It was far more complex than I first imagined it to be. You can look for “Vertical Amplifier Circuits” by Tektronix. On channel 2, the drain voltage is I read about the design, dont remember where, of the input amplifier to the Tek scope. Search Dattasheet Within This Topic. Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life.

The information in this document is subject to change without notice. Subject of the new topic: No part of this document may be copied or reproduced in any form or by any means without datssheet prior written. Vertical input designs where the input can vary over a wide range like with differential amplifiers take special steps to maintain a constant drain current. For a 20 MHz oscilloscope, it would be difficult to find a small signal JFET which is too slow and that is why it worked.


The recommended applications of.

Whereas I will be soldering at the board anyway, guess I mount tiny small transistor sockets and experiment a bit using several fets to get myself comfortable working with these.

In this schematic high frequencies go to Q while low frequencies go through U and Q How is it that this scope works with this jfet at all?

Discussion in ‘ Pioneer Audio ‘ started by gslikkerAug 1, Are the FETs deteriorated? Yes, my password is: It looks very nice, and it is in original condition. There are several curves plotted, should I measure Vgs off for a particular jfet and then use the curve that starts at that Vgs off voltage?

Hello all, Short version: Now, I would like to hear the experts evaluation of this SA control amp schematic. When I got them in, and was trying to decide whether to use the 2SK30A or the 2SK first I discovered that they’re both for “audio frequencies”.
