TK5A45DA
1. Applications
• Switching Voltage Regulators
2. Features
(1) Low drain-source on-resistance: RDS(ON) = 1.52 Ω (typ.)
(2) High forward transfer admittance: |Yfs| = 1.5 S (typ.)
(3) Low leakage current: IDSS = 10 µA (max) (VDS = 450 V)
(4) Enhancement mode: Vth = 2.4 to 4.4 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).
