TOSHIBA Field Effect Transistor Silicon N-Channel MOS Type (π-MOSIV) 2SK3742 Switching Regulator Applications

• Low drain-source ON resistance: RDS (ON) = 2.2 Ω (typ.)
• High forward transfer admittance: |Yfs| = 3.5 S (typ.)
• Low leakage current: IDSS = 100 μA (VDS = 720 V)
• Enhancement model: Vth = 4.0~5.0 V (VDS = 10 V, ID = 1 mA) Absolute Maximum Ratings (Ta = 25°C) Characteristic Symbol Rating Unit Drain-source voltage VDSS 900 V Drain-gate voltage (RGS = 20 kΩ) V DGR 900 V Gate-source voltage VGSS ±30 V DC (Note 1) I D 5 Drain current Pulse (t = 1 ms) (Note 1) IDP 15 A Drain power dissipation (Tc = 25°C) PD 45 W Single pulse avalanche energy (Note 2) EAS 595 mJ Avalanche current IAR 5 A Repetitive avalanche energy (Note 3) E AR 4.5 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 R th (ch-c) 2.78 °C/W Thermal resistance, channel to ambient R th (ch-a) 62.5 °C/W Note 1: Ensure that the channel temperature does not exceed 150°C during use of the device. Note 2: V DD = 90 V, Tch = 25°C (initial), L = 43.6 mH, IAR = 5.0 A, RG = 25 Ω Note 3: Repetitive rating: pulse width limited by maximum channel temperature This transistor is an electrostatic-sensitive device.
