TK14A55D
TOSHIBA Field Effect Transistor Silicon N Channel MOS Type (π-MOS)
TK14A55D
Switching Regulator Applications
Low drain-source ON-resistance: RDS (ON) = 0.31 Ω (typ.)
High forward transfer admittance: Yfs= 6.5 S (typ.)
Low leakage current: IDSS = 10 μA (max) (VDS = 550 V)
Enhancement mode: Vth = 2.0 to 4.0 V (VDS = 10 V, ID = 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).

Note 1: Ensure that the channel temperature does not exceed 150°C.
Note 2: VDD = 90 V, Tch = 25°C (initial), L = 4.6 mH, RG = 25 Ω, IAR = 14 A
Note 3: Repetitive rating: pulse width limited by maximum channel temperature
This transistor is an electrostatic-sensitive device. Handle with care.
