Unit: mm
• High breakdown voltage: V_GDS = −50 V
• High input impedance: I_GSS = −1 nA (max) (V_GS = −30 V)
• Low noise: NF = 0.5dB (typ.) (R_G = 100 kΩ, f = 120 Hz)
• Small package

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