TOSHIBA Field Effect Transistor Silicon N Channel Junction Type
2SK371
For Low Noise Audio Amplifier Applications
• Suitable for use as first stage for equalizer and MC head amplifiers.
• High |Yfs|: |Yfs| = 40 mS (typ.) (VDS = 10 V, VGS = 0, IDSS = 5 mA)
• High breakdown voltage: VGDS = −40 V
• Super low noise: NF = 1.0dB (typ.)
(VDS = 10 V, ID = 0.5 mA, f = 1 kHz, RG = 100 Ω)
• High input impedance: IGSS = −1 nA (max) (VGS = −30 V)
• Small package

Note:
Using continuously under heavy loads (e.g. the application of
JEDEC
―
high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the
JEITA
―
reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the

absolute maximum ratings.
Weight: 0.13 g (typ.)
Please design the appropriate reliability upon reviewing the
Toshiba Semiconductor Reliability Handbook (“Handling Precautions”/“Derating Concept and Methods”) and
individual reliability data (i.e. reliability test report and estimated failure rate, etc).

Note 1: IDSS classification GR: 5.0~10.0 mA, BL: 8.0~16.0 mA, V: 14.0~30.0 mA
Note 2: Use this in the low voltage region (VDS < 15 V) for low noise applications.
