JFE2140: Possible datasheet typo error

Part Number: JFE2140
Other Parts Discussed in Thread: JFE150,

Could the "Input gate current" specification in the rev A datasheet a typo?

V_DS = 0 V,
V_GS = –30 V

T_A = 25°C

I_G = 0.2 pA typ / 60 pA max? <-- could the unit be nA instead of pA?

As far as I can see, rev. A has not yet been published. (The first revision is SLPS730 without a suffix.)

The JFE150 datasheet mentions the test condition "V_GS = −0.7 V" for this value. This gate voltage is near the best case (see figure 6-7), so pA is correct.

Hello,

+/- 60 pA is correct for room temperature, the JFETs and clamps connected to the gate both exhibit very low leakage.

Please let me know any more questions about the JFE2140!

Best Regards,
Mike
