TOSHIBA Field Effect Transistor Silicon P Channel Junction Type
2SJ108
2SJ108
Low Noise Audio Amplifier Applications
Recommended for first stages of EQ amplifiers and MC head
amplifiers.
High |Yfs|: |Yfs| = 22 mS (typ.)
(VDS = 10 V, VGS = 0, IDSS = 3 mA)
Low noise: En = 0.95 nV/Hz1/2 (typ.)
(VDS = 10 V, ID = 1 mA, f = 1 kHz)
High input impedance: IGSS = 1.0 nA (max) (VGS = 25 V)
Complementary to 2SK370

Note:
Using continuously under heavy loads (e.g. the application of
high temperature/current/voltage and the significant change in
temperature, etc.) may cause this product to decrease in the

reliability significantly even if the operating conditions (i.e.
operating temperature/current/voltage, etc.) are within the absolute maximum ratings.
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).
