2SK117
Low Noise Audio Amplifier Applications
Unit: mm
• High |Yfs|: |Yfs| = 15 mS (typ.) (VDS = 10 V, VGS = 0)
• High breakdown voltage: VGDS = −50 V
• Low noise: NF = 1.0dB (typ.)
(VDS = 10 V, ID = 0.5 mA, f = 1 kHz, RG = 1 kΩ)
• High input impedance: IGSS = −1 nA (max) (VGS = −30 V)

Note:
Using continuously under heavy loads (e.g. the application of
high temperature/current/voltage and the significant change in
JEDEC
TO-92
temperature, etc.) may cause this product to decrease in the
JEITA
SC-43
reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the
TOSHIBA
2-5F1D
absolute maximum ratings.
Please design the appropriate reliability upon reviewing the
Weight: 0.21 g (typ.)
Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and
individual reliability data (i.e. reliability test report and estimated failure rate, etc).
