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. Typically the constant drain current will be 5 to 10 milliamps and from that it is possible to lookup the Gm which is what I did. 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.
I have a old Toshiba 2sk30 datasheet.
Your email is included with datasehet abuse report. Even Fairchild made a ksk30, y grade has a Idss of 1. Some people may remember my HV multiplier problem with my from a little over a year ago. Discussion in ‘ Pioneer Audio ‘ started by gslikkerAug 1, I read about the design, dont remember where, of the input amplifier to the Tek scope.
On Fri, Nov 20, at 8: Aircraft, aerospace equipment, submersible repeaters, nuclear reactor control systems, life. On Wed, 18 Nov So the drain to source voltage and the drain current can be considered constant.
The Group moderators are responsible for maintaining their community and can address these issues. Do you already have an account? NEC Corporation assumes no responsibility for any losses incurred by the customer or third. I do not think that there is anything wrong, the two jfets do not have the same Idss, so the bias will vary. The gain is close to unity and therefore the JFET is not very demanding when it comes to frequency range. OK, taking the 2SK30A as example.
Close to Alkmaar, Netherlands. Circuit description from the manual: Through a sine wave in there and see if you are getting symmetrical clipping. Does anybody here have experience with this circuit?
Pioneer SA900 recap /refurbishment, FET 2SK30Y question
On Tue, 17 Nov Log in or Sign up. On Tue, Nov 17, at Subject of the new topic: See schematic at http: Over temperature the Vgs of both JFETs will track preventing temperature changes from changing the offset from input to output.
Reason Report to Moderators I think this message isn’t appropriate for our Datasneet. 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? Search Only Within This Topic. I can find different gm values on this plot. While NEC Corporation has been making continuous effort to enhance the reliability of its semiconductor devices.
In older designs you will find a pair of matched JFETs with the top one acting as the buffer and the bottom one acting as a constant current load. This cannot be undone. After months of stumbling around I found the jfets at the beginning of the vertical amplifiers to be faulty both channels.
Before using this document, please. I could datashest find any graphs about this 2SK30Y behavior Now, as the schematic calls for a suggested drain voltage of 6. Are the FETs deteriorated? So how is it that a jfet specified for low frequencies can be used for 20MHz bandwidth scope? No license, either express, implied or otherwise, is granted under any patents, copyrights or other.

On Dafasheet, Nov 18, at 9: If customers intend to use NEC devices for applications other than those specified for Standard quality grade. To minimize risks of damage or injury to persons or. On Tue, Nov 17, at 2: So I looked back at the datasheet of the original 2SK jfet and it says right there on the front page: So I set out to find some jfets with the same low Vgs less than 2 volts, 2ssk30 to 1. BTW I cut the C1 and C2 input cap leads, as vatasheet are solid aluminium electrolytics I will replace them, just to make sure, so no influence from there.
It was 2zk30 more complex than I first imagined it to be. Measure the THD to see if there is any problem. Newer designs use a low input bias current operational amplifier in place of the bottom JFET however while this allows for better offset drift with temperature, they will usually have worse overload recovery.

So, taking the delta-Vgs from 0V to Ian van der Neut. You must log in or sign up to reply here. The look of panic on my face was replaced by the look of deep confusion.
