TK5P53D Datasheet, PDF (1/5 Pages) Toshiba Semiconductor – Switching Regulator Applicatieons

TK5P53D
Silicon N Channel MOS Type (π-MOSⅦ)
Switching Regulator Applications
• Low drain-source ON-resistance: R_{DS (ON)} = 1.2 Ω (typ.)
• High forward transfer admittance: ⎪Y_fs⎪ = 2.8 S (typ.)
• Low leakage current: I_DSS = 10 μA (max) (V_DS = 525 V)
• Enhancement-mode: V_th = 2.4 to 4.4 V (V_DS = 10 V, I_D = 1 mA)

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).
