Re: PN 1855-0064

 

I'm not sure if you were asking if these meet the spec but I wanted to clarify how your finding verify the earlier numbers (for myself as much as future readers).

I believe the spec of Idss@Vgs0 is 1mA "or greater". The Drain-Source current when fully on (Vgs=0) is a primary characteristic of a JFET. Being able to pass more current than specified is OK. So an IDss of 2.5 or 4.2mA exceeds the minimum specification.

Thank you both for chiming in.??

The unit is a 7562A, I apologize for the typo.

I pulled a couple from another board and measured one side of each package, presumption is the other is similar.

I was tweaking with the settings so some inconsistencies below.? ?The pinch off voltage range based on the two sets is between -1.6V and -2.2V.? IDSS 2.6 to 4.2mA at 10V VDS.
