2SK170 (BL) Toshiba Matched Quad (4 ea)

Up for sale are quads of new original stock (NOS) genuine guaranteed authentic Toshiba N-channel 2SK170BL audio JFETS made in Japan.

The Idss (drain current for zero bias) and Yfs (transconductance @Idss) were recorded under constant ambient conditions by curve-tracing a large batch (single lot#) BL-grade 2SK170 JFETS. The Yfs vs. Idss distribution for this batch of transistors is shown in the last picture. Measured Idss is in the range 6.5-10.5 mA and Yfs is 32-38 mS.

The JFETs were sorted into individual bins of 4 (quads) with highly similar measured values for Idss (difference < 0.03 mA) and Yfs (difference < 1 mS).

The buyer may request a desired Idss range for the quad, but please enquire before purchase.

The four devices in each quad are individually labeled and will be provided with the measurement data (see EXAMPLE in photo). The JFETs are shipped in a sealed black anti-static bag inside a bubble-padded envelope.
