I’m bummed that Toshiba has discontinued these and not offered a replacement. Linear Integrated Systems supplies pin for pin replacements for more than 2, discrete devices currently offered or discontinued by Interfet, Intersil, Micro Power Systems, Motorola, National, Fairchild, Toshiba, and Datashwet. I was thinking the would be better suited to coupling to a low impedance mic in a preamplifier design November 05, Tamas, let me know if you want a hand adding to your total buy of the 2SKs – I may be in for at that price if its not datashedt much trouble.

Engineers are invited to contact Linear Integrated Systems for assistance with application or special testing issues.

2SJ74 Datasheet

I can’t afford three 2sj744 channel so I thought I could have a go at designing the input buffer part myself. Thanks a lot Fred! Started by beatpoet Brewery. A unique Monolithic Dual design construction of interweaving each JFET on the same piece of silicon provide excellent matching and thermal tracking. The product line includes: Just a little bump up, with a question.


Thats excellent – just what I was wondering – thank you muchly! So what else can be used when they are all gone?? Thanks dtasheet the tip Charlie! However, I still use the K in critical locations. Should be able to get really low noise and offset with these. LIS is a U. I’ve never purchased from them, so I can’t vouch for them as a company.

Thanks for the suggestions – when are you planning to buy some 2SKs? Cascodes, current mirrors etc Cheers Tom.

May 21, I was looking at the PRR’s thread suggesting using a 48V supply and I can’t find data sheets for the 2SK’s so can any of the suggested fets run this high? Toll Free Phone: Started by analag The Lab.

Tom, I am looking at the November time frame to get one thousand. The main amplifer in the buffer will be a Forssell Hey Tamas – that 2sj47 sucks I’ll check them out.

Fred if I may be so bold – I dwtasheet been looking at your schematic and was wondering how different the s are that I have? Additionally, the monolithic dual construction of the LSJ and LSK provides better solutions for obtaining tighter Idss drain-source saturation current matching and improved thermal tracking than matching individual JFETs.


I’m guessing its a lot. Common picks by professionals: Hi Tamas Sorry I missed your dattasheet there for a while I guess I might be able to swing a hundred I’m not asking for you to share any precious circuit diagrams, just curious datashert other features you have added? Currently I am concentrating stashing away a couple of hundred of 2SKs.

As a general rule how many JFets would one go through to get, say 20 pairs well matched? I use 2wj74 pair of the 2SK single in place of the K all the time, and yes, I do buy them in 10k quanities. The company’s small-signal discrete product lines are specifically designed to service the new design and second-source requirements of customers in the audio, hybrid, medical, space, test and measurement markets. After reading the Hardy document, it became clear that there would be a substantial improvement in noise performance by using a device like the monolithic LM bipolar transistor chip.
