2SK2145 TOSHIBA Field Effect Transistor Silicon N Channel Junction Type 2SK2145 Audio Frequency Low Noise Amplifier Applications * Including two devices in SM5 (super mini type with 5 leads.) * High |Yfs|: |Yfs| = 15 mS (typ.) at VDS = 10 V, VGS = 0 * High breakdown voltage: VGDS = -50 V * Low noise: NF = 1.0dB (typ.) Unit: mm at VDS = 10 V, ID = 0.5 mA, f = 1 kHz, Rg = 1 k * High input impedance: IGSS = -1 nA (max) at VGS = -30 V Marking Pin Assignment (top view) Absolute Maximum Ratings (Ta = 25C) (Q1, Q2 common) Characteristics Gate-drain voltage Gate current Drain power dissipation Symbol Rating Unit VGDS -50 V IG 10 mA 300 mW PD (Note 1) Junction temperature Tj 125 C Storage temperature Tstg -55 to 125 C Note: JEDEC JEITA TOSHIBA 2-3L1C Weight: 0.016 g (typ.) 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).
