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: Note 1: Mounted on FR4 board 2 (25.4 mm × 25.4 mm × 1.6 t, Cu pad: 645 mm ) Note 2: The pulse width limited by max channel temperature. Marking Equivalent Circuit 3 3 KDK 1 2 1 2 Handling Precaution When handling individual devices (which are not yet mounted on a circuit board), be sure that the environment is protected against electrostatic electricity. Operators should wear anti-static clothing, and containers and other objects that come into direct contact with devices should be made of anti-static materials. The Channel-to-Ambient thermal resistance Rth (ch-a) and the drain power dissipation PD vary according to the board material, board area, board thickness and pad area, and are also affected by the environment in which the product is used. When using this device, please take heat dissipation fully into account. 1 2007-11-01 SSM3K14T Electrical Characteristics (Ta = 25°C) Characteristic Symbol Gate leakage current Min Typ.
