1 / 6 page 2SK3947 2006-11-08 1 TOSHIBA Field Effect Transistor Silicon N-Channel MOS Type (π-MOSVI) 2SK3947 Switching Regulator Applications • Low drain-source ON-resistance: RDS (ON) = 1.1 Ω (typ.) • High forward transfer admittance: |Yfs| = 5.0S (typ.) • Low leakage current: IDSS = 100 μA (VDS = 600 V) • Enhancement mode: Vth = 2.0~4.0 V (VDS = 10 V, ID = 1 mA) Absolute Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unit Drain-source voltage VDSS 600 V Drain-gate voltage (RGS = 20 kΩ) VDGR 600 V Gate-source voltage VGSS ±30 V DC (Note 1) ID 6 Drain current Pulse (t = 1 ms) (Note 1) IDP 24 A Drain power dissipation (Tc = 25°C) PD 40 W Single-pulse avalanche energy (Note 2) EAS 345 mJ Avalanche current IAR 6 A Repetitive avalanche energy (Note 3) EAR 4 mJ Channel temperature Tch 150 °C Storage temperature range Tstg −55~150 °C 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). Thermal Characteristics Characteristic Symbol Max Unit Thermal resistance, channel to case Rth (ch-c) 3.125 °C/W Thermal resistance, channel to ambient Rth (ch-a) 62.5 °C/W Note 1: Ensure that the channel temperature does not exceed 150°C. Note 2: VDD = 90 V, Tch = 25°C (initial), L = 16.8 mH, IAR = 6 A, RG = 25 Ω Note 3: Repetitive rating: Pulse width limited by maximum channel temperature This transistor is an electrostatic-sensitive device. Handle with care. Unit: mm 1: Gate 2: Drain 3: Source JEDEC ― JEITA SC-67 TOSHIBA 2-10U1B Weight: 1.7 g (typ.) 1 3 2 |
