Description :

TK12A50D TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (π-MOSⅦ) TK12A50D Switching Regulator Applications • • • • Low drain-source ON-resistance: RDS (ON) = 0.45 Ω (typ.) High forward transfer admittance: |Yfs| = 6.0 S (typ.) Low leakage current: IDSS = 10 μA (VDS = 500 V) Enhancement mode: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 1 mA) Unit: mm Absolute Maximum Ratings (Ta = 25°C) Characteristics Drain-source voltage Gate-source voltage DC Drain current (Note 1) Symbol VDSS VGSS ID IDP PD EAS IAR EAR Tch Tstg Rating 500 ±30 12 48 45 364 12 4.5 150 -55 to 150 http://www.DataSheet4U.net/ Unit V V A W mJ A mJ °C °C 1: Gate 2: Drain 3: Source Pulse (t = 1 ms) (Note 1) Drain power dissipation (Tc = 25°C) Single pulse avalanche energy (Note 2) Avalanche current Repetitive avalanche energy (Note 3) Channel temperature Storage temperature range JEDEC JEITA TOSHIBA ― SC-67 2-10U1B Weight: 1.7 g (typ.) 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 2 Characteristics Thermal resistance, channel to case Thermal resistance, channel to ambient Symbol Rth (ch-c) Rth (ch-a) Max 2.78 62.5 Unit °C/W °C/W 1 Note 1: Ensure that the channel temperature does not exceed 150℃. Note 2: VDD = 90 V, Tch = 25°C(initial), L = 4.3 mH, RG = 25 Ω, IAR = 12 A Note 3: Repetitive rating: pulse width limited by maximum channel temperature This transistor is an electrostatic-sensitive device.
